May 2012 Volume 14, No. 5New MTS 4100 NVHAnalyzer IdentifiesVibration SourcesAsk any group of auto technicians to name their most challenging diagnostic situations, and you can count on somebody mentioning vibration analysis. Over the years, a numberof diagnostic tools and procedures have been developed to helplocate and resolve vibrations. Technicians with the most notchesin their toolboxes can name quite a few — the reed tachometer,driveline inclinometer, multiple orders of vibration, strobe, ChassisEar, match-mounting, radial force variation, the EVA, and others.New diagnostic aids always have been developed to take advantageof the new technology that is available. At the present, designershave a lot to work with — powerful computers, data collection capability, precision accelerometers, high resolution graphic displays, and thevehicle’s own serial data. The new MTS 4100 NVH Analyzer and GMDealer Equipment can now offer this capability.What is the MTS 4100?The MTS 4100 is an NVH (noise, vibration, harshness) analyzer combining all of thetools required to diagnose the most challenging vehicle NVH conditions.ContentsTIP: For now, the MTS 4100is not mentioned in Service Information (SI) procedures, but itcan be used in place of the EVA(Electronic Vibration Analyzer) withgreater effectiveness.New MTS 4100 NVH Analyzer IdentifiesVibration Sources . . . . . . . . . . . . . . . . . . . . . . . . . . 1New Design Rear Axle Output Sealand Axle Shaft. . . . . . . . . . . . . . . . . . . . . . . . . . . . . 3Under Body Noise on Uneven Road Surface. . . . . . 3New 8-Pin Mass Air Flow, Humidity, BAROand Intake Air Temperature 1 and 2 Sensor . . . . . . 4Wheel Alignment Specifications Updated in 2012. . 4New Fuel Module Design . . . . . . . . . . . . . . . . . . . . 5Leak Diagnosis Using Leak Trace Powder . . . . . . . 5Multi-Axis Acceleration Sensor ModuleSets History DTC . . . . . . . . . . . . . . . . . . . . . . . . . . 5Radio Frequency Interference andVehicle Security. . . . . . . . . . . . . . . . . . . . . . . . . . . . 6Blower Motor Inoperative after BlowerControl Module Replacement. . . . . . . . . . . . . . . . . 6Intermittent Service Power SteeringMessage with DTC U0131 . . . . . . . . . . . . . . . . . . . 6Waiting to Initialize Message. . . . . . . . . . . . . . . . . . 7Service Replacement Engines withTemporary Emission Exemption Tag. . . . . . . . . . . . 7Potential History DTCs after Servicinga Vehicle . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 8Service Know-How . . . . . . . . . . . . . . . . . . . . . . . . . 8Car Issues – Fix It Right the First Time. . . . . . . . . . 9Truck Issues – Fix It Right the First Time . . . . . . . . 9The MTS 4100 allows techniciansto find the root cause of vibrations without having to experimentally replace part after part,and without the need for makingtime-consuming calculations. TheMTS 4100 can also perform systemdriveline balance without the needto remove a single part from thevehicle being tested.The MTS 4100 employs a 320x 240 LCD graphic display and22 function keys to monitor andcontrol its various functions. Itaccepts inputs from multiple accelerometers, a microphone,and vehicle serial data (using theJ-1962 connector). It can outputcontinued on page 2MTS 4100 NVH Analyzer KitCustomer Care and Aftersales
New MTS 4100 NVH Analyzer IdentifiesVibration Sources – continued from page 1data to a printer or a PC using an RS232 port. The MTS 4100 alsoworks with a strobe and a photo tachometer for rotational speed measurements and a remote trigger switch.Operation is simplified by multiple menus and automated data collection. The MTS 4100 specifically identifies the vehicle subsystem that is causing the excess noise or vibration and, in manycases, the actual component within that subsystem.What are the Advantages of the MTS 4100?When compared with the EVA, the MTS 4100 offers several important features and advantages. Direct connection to vehicle data communication – provides vehiclespeed, engine speed, driveshaft speed, and wheel speed at a givenroad speed to correlate different sources of vibration On-screen, step-by-step instructions Accurate isolation – accurately isolates the source of vibration ornoise related to tires, wheel assemblies, engine, drivetrain and engine accessoriesThe tool rank orders vehicle components byfrequency and energy level. Capability to tie vibration to each source – driveline, tire/wheel,engine, and engine accessories Suggests corrective actionand compares the vibration frequencies with the frequenciesassociated with various rotating components within the vehicle(driveshaft, engine RPM or wheels/tires). After the MTS 4100has correlated the vibration data with the vehicle’s OBD II data,it provides recommendations regarding possible causes of thevibration. Operates quickly – enables one technician to balance a driveline inonly 15 minutes Multiple vibration channels – allows the vehicle to be divided intozones so the vibration can be isolated Better sensitivity – the accelerometers are more sensitive and candetect lower levels of vibrationThe noise diagnostics function is similar to the vibration diagnostics function but the MTS 4100 measures noise from one or twomicrophones instead of accelerometers that measure vibration. Can track multiple vibration sources Intelligent displays – includes rank-order of vibration sources and agraphic display that shows each source and its intensitySupport for either one-plane or two-plane driveshaft balancing isprovided by one or two accelerometers and a photo tachometerconnected to the MTS 4100. The accelerometers measure thevibrations at both ends of the driveshaft, while the photo tachometer measures the rotational speed of the driveshaft and providesa position reference. The MTS 4100 directs the technician througha step-by-step balancing procedure, and then provides a graphical indication of where to mount the balancing weight. A final stepverifies that the driveshaft has been adequately balanced. No technician calculation of vibration required Driveline balancing feature – for single or dual plane prop shafts Complements radial force variance machines – by identifying theproblem area with no additional technician time Storage and playback of road test events – so data can be reviewed off-line by technician and customerThe MTS 4100 also can control output to a strobe light, such as astandard timing light. The flashes of the strobe light, synchronizedwith the vibration, help isolate the source of the vibration. Thetechnician can select the frequency of the strobe output and havethe analyzer output a frequency that is related to the frequenciesof the rotating components of the vehicle. For example, a strobecan be generated that is half the frequency of the engine RPM(i.e., rotation rate of the camshaft). Available high resolution microphoneHow is the MTS 4100 Used?The MTS 4100 NVH Analyzer provides four main operatingmodes: Vibration diagnostics Noise diagnostics Driveshaft balancingHow is the MTS 4100 Obtained? Strobe light capabilityThe new Vetronix MTS 4100 NVH Analyzer is now availablefrom GM Dealer Equipment. For more information, visitwww.gmdesolutions.com.For vibration diagnostics, the MTS 4100 measures data froma single accelerometer or simultaneously from two accelerometers, and obtains OBD II data from the vehicle’s network. Itthen performs a frequency analysis on the accelerometer data,Thanks to David MacGillis2May 2012
New Design Rear Axle Output Seal and Axle ShaftDuring the 2012 model year, a seal change and an axle shaftchange were made on the rear axle output seals on AWD versions of the 2012 LaCrosse and SRX.The old style seal is black and the axle shaft that mates with itdoes not have a slinger. The black (first design) seal is GMP/N 20986535.The new style seal material is yellow and it mates with an axleshaft that has an integral slinger. The yellow (second design)seal is GM P/N 22845699.New style yellow sealTIP: Do not mix the different seals and axle shafts. Installingfirst design seals with the second design axle shafts OR installing second design seals with first design axles shafts will resultin a leak.Old style black sealIf a rear axle component is incorrectly ordered and it comeswith a seal that is incompatible with the vehicle’s axle shafts,it is not necessary to return the part. Simply get the axle sealthat matches the existing axle shafts and replace the seal(s)using the seal replacement procedure in the appropriate Service Information.Thanks to David MacGillisUnder Body Noise on Uneven Road Surface2008-2012 Malibumodels may experience a noise heardfrom under thefront of the body or suspension area.The pop, snap,creak or clunk noisemay be present onbraking, turning ordriving on an unevenroad surface.The noise may becaused by the frontcradle body mountbolt washers or cradle making contactwith the frame rail.The body bolt mount washers and rail flangeshould have 5 mm clearance.Inspect the washerto-cradle clearance and the cradle-to-frame rail flange clearance.

New 8-Pin Mass Air Flow, Humidity, BARO andIntake Air Temperature 1 and 2 Sensor in Gasolineand Duramax Diesel EnginesBeginning with the 2012 model year,a new 8-pin Mass Air Flow (MAF), Humidity, Barometer (BARO) and Intake Air Temperature (IAT) 1 & 2sensor is being used on some gasolineengines.There are two suppliers of the 8-pinsensor, Bosch and Hitachi. The Hitachisensor is used on most of the applications at this time. The sensors are alsoknown as the Multifunction Intake Airsensor or mini-weather station sensor.The new sensor measures the intakeair’s humidity. A second air temperaturesensor is housed in the assembly to accurately measure the air temperatureat or very near the humidity sensor.The ECM uses the air temperatureto calculate the air humidity, which isdisplayed by the scan tool as Intake AirHumidity (%). The signal is transmitted on the circuit as duty cycle (%).The intake air temperature sensor 2 is transmitted to the ECM as a frequency(Hz), on the same circuit as the humidity signal. The scan tool displaysthe IAT sensor 2 in degrees ( C / F)and frequency (Hz).Harness and internal sensor differences do not permit interchangeabilitybetween the Hitachi and Bosch sensors. However, both have the following functions: MAF sensor IAT sensor 1 BARO sensor (Throttle Inlet Air Pressure – TIAP) Humidity sensor IAT sensor 2 (Humidity Air Temperature)The Hitachi sensor terminals are connected to the vehicle and the ECMas follows:The diesel engines use two of the sensor’sfunctions: Pin 1 – Signal, IAT 1 IAT sensor 1 (Humidity Air Temperature) Pin 2 – 5V Reference Pin 3 – Low Reference Pin 4 – Signal, BARO (TIAP) Pin 5 – Ignition, 12V Pin 6 – Signal, MAF Pin 7 – Ground, Chassis Pin 8 – Signal, Humidity (duty cycle –%) and IAT 1 (frequency – Hz)The Bosch sensor terminals are connected to the vehicle and the ECM asfollows: Pin 1 – Signal, Humidity (duty cycle –%) and IAT 1 (frequency – Hz) Pin 2 – 5V Reference Pin 3 – Signal, MAF Pin 4 – Ground, Chassis Pin 5 – Ignition, 12V Pin 6 – Signal, BARO (TIAP) Pin 7 – Low Reference Pin 8 – Signal, IAT 1The gasoline engines replace theMass Air Flow/Intake Air Temperature(MAF/IAT) 5-pin sensor with the 8-pinMultifunction Intake Air sensor.The 6.6L Duramax diesel engines(RPOs LML, LGH) will use the newHitachi 8-pin sensor for the first time inthe 2013 model year. For diesels, theMultifunction Intake Air sensor is usedwith the existing MAF/IAT 5-pin sensor.The new sensor is in the diesel’s airstream, ahead of the existing MAF/IAT, requiring a shift of some intake air sensor names: New IAT sensor (integrated with theHumidity sensor) is IAT 1 Old IAT sensor 1 (integrated with theMAF sensor) becomes IAT 2 Old IAT 2 (located before the inlet tothe Charge Air Cooler) becomes IAT 3The diesel engines use three of theeight pins of the Hitachi sensor: Pin 5 – Ignition voltage Pin 7 – GroundA. Current 5-pin sensorB. New 8-pin sensor Pin 8 – Signal, Humidity (duty cycle –%) and IAT 1 (frequency – Hz) Humidity sensorTIP: The diesels use different/new DTCsfor similar sensors used on gasoline engines.For a list of 2012 and 2013 DTCs forMultifunction Intake Air Sensors, go to GMTechLink on GlobalConnect.Thanks to W. Michael SchallmoWheelAlignmentSpecificationsUpdated in2012Recently in TechLink, (March 2012) theimportance of double-checking wheelalignment specifications was highlighted.The only recommended source of current,accurate wheel alignment specifications(both targets and tolerances) is the ServiceInformation. The specifications indicatedon the wheel alignment rack should alwaysbe verified with the appropriate ServiceInformation.In the first quarter of 2012, the following models had updated/changed wheel alignment specifications: 2007-2012 Acadia 2007-2012 Enclave 2009-2012 Traverse 2010-2012 Corvette 2010-2012 LaCrosse 2011-2012 RegalCheck the alignment specifications forthese models in the appropriate ServiceInformation against the alignment machine specifications before performing analignment. Be sure to take into accountall related option content on the vehicle,including tire and suspension RPOs. Theseupdated specifications most likely will notbe included in the latest specifications fromalignment machine manufacturers.Not using the correct specifications asshown in the Service Information may resultin a warranty claim being subject to review.Thanks to David MacGillis4May 2012
New Fuel ModuleDesignLeak Diagnosis UsingLeak Trace PowderACDelco recentlymade changesto several fuel modules to further enhancetheir performance. Thetiming of thechanges for eachpart numberhas varied, but implementationof the changesbegan last summer.Continued refinement of engineering, materials, and manufacturingprocesses has greatly reduced the occurrence of fluid leaks (engineoil, transmission fluid, coolant, power steering fluid, and brake fluid). Although rare, fluid leaks occasionally occur, so locating the source offluid leaks remains an important skill for technicians to master.There is some important information about leak diagnosis in the ServiceInformation. In addition, leak diagnosis was discussed in the April 2012Emerging Issues seminar.One of the methods mentioned requires the use of leak trace powder.Here are some highlights.Because the customer has probably driven the vehicle for awhile withthe leak, the fluid will be splattered about and the source of the fluid leakwill not be obvious. Attempt to identify the type of fluid from the color,smell and feel of the fluid.Then, thoroughly wipe thesuspected leak area witha shop towel.When replacinga fuel module,you may havenoticed some ofthese new designchanges:A. The pump changed from a Gerotor pump to a Generation 4 Turbine pump, which is quieter and more durable.B. The module plastic material changed to a more fuelresistant Acetyl plastic that provides an improved highalcohol fuel tolerance.C. Guide rods were reduced from 3 to 2, which retainsproper alignment while reducing pinching.D. Jet pump has been added to help maintain fuel in thereservoir.E. The float material is more fuel resistant for longer life.F. The external strainer has been moved inside the fuelmodule to help reduce the chance of puncture.G. Some float arms and pivot points have changed; however, the fuel level sensor output has not changed.While the appearance of the fuel modules has changed,the fit, form and function has not. In addition, the partnumbers did not change.To address any concerns regarding the productchanges, a special notice is included inside each box explaining that the module has undergone changes.Thanks to Dan CarterTIP: Do not use brakecleaner or other reactivesolvents. These solventscan damage rubber gaskets, seals and bushings.After cleaning the suspected leak area, sprayaerosol-type leak tracingpowder to cover the area.A leak can be traced through thepowder back to the source.Drive the vehicle for15–20 minutes undercity driving conditions until normal operating temperatures are reached.Do not drive at highway speeds because this will cause the leaking fluidto spread.Trace the leak path through the powder back to the source of the leakand make the necessary repairs.Additional Uses for Leak Trace PowderLeak trace powder also can be used to determine if proper contactis being made between seals on weatherstrips around doors, trunks,hatches, and sunroofs.Spray the powder on the frame where the seal should make contactand then gently close the panel. Open the panel and inspect the seal.The powder will transfer to the seal where contact is made. Gaps in the powder on the seal indicate a possible wind or water leak area.Thanks to Dave PeacyMulti-Axis Acceleration Sensor Module SetsHistory DTCWhen performing a DTC check using ascan tool on the 2013 Malibu, the MultiAxis Acceleration Sensor Module mayhave a DTC U0121 (Loss of Communication with the EBCM) set in history. Ifthe DTC is cleared, it may set again andimmediately go to history during the nextMay 2012ignition cycle. No messages or warninglamps will display.This is a characteristic of normal operation. Do not replace any parts or attemptto repair. At key-up, the Multi-Axis Acceleration Sensor Module is looking5for a response from the Electronic Brake Control Module (EBCM) right away. Because it does not receive the responseimmediately, it sets DTC U0121 momentarily and then goes to history.Thanks to Christopher Crumb

Potential History DTCs after Servicing a VehicleWhen servicing a vehicle, any control module that wakes up witha circuit disconnected may set a current DTC, which will go intohistory once the circuit is reconnected. This condition is related tohow the vehicle power mode works with different control moduleswith the key On vs. the key Off. These DTCs often are set inadvertently by waking a control module when opening a door andwill not clear until the proper self-test has been completed, whichdepends on operating conditions being met.If a technician were to leave the Intake Air Temperature/Mass AirFlow (IAT/MAF) sensor disconnected and open the driver’s doorwith the battery connected, ignition Off, and the ECM “asleep,”the Body Control Module (BCM) would wake up the ECM, causing the ECM to sense the open IAT sensor and set a current DTCP0113. After the IAT sensor is reconnected, the DTC status willclear as a current DTC, but it will still be in stored in history.This is just one example. There are others that may occur whenother sensors are disconnected and a control module wakes up.Here’s an example of how a history DTC could be set on 20102013 vehicles that require the GDS 2 scan tool for vehicle communication (2010-2012 LaCrosse; 2011-2012 Regal; 2012Verano; 2010-2012 SRX; 2010-2012 Camaro, Equinox; 2011-2012Cruze, Volt; 2012 Sonic; 2013 Malibu; and 2010-2012 Terrain).A history DTC P0113 (Intake Air Temperature Sensor Circuit HighVoltage) may be stored immediately after vehicle service if theEngine Control Module (ECM) wakes up (activates) while a 5-voltreference sensor is unplugged and the ignition is Off.10212.05D Emerging IssuesServiceKnow-HowIf this condition occurs during unrelated vehicle repairs, do notreplace any parts.
