BB1Test and Adjustment JobsEngine 104, 119, 120 LH-SFIEngine Test, AdjustmentNotes regarding on/off ratio check using on/off ratio testerThe operation of the on-off ratio control can be tested by checking theon-off ratio. In addition, any malfunctions that exist momentarily can berecognized. The tests distinguish between malfunctions that occur with theignition ON or with the engine at idle.The on-off ratio can be checked using the on-off ratio tester or engineanalyzer. An on-off ratio of 50% indicates that all input signals are OK, buton-off ratio control is not functioning. A varying on-off ratio indicates thatthe on-off ratio control is functioning correctly. On-off ratios from 10% to95% are each assigned a specific malfunction (see DTC memory, DMEngines, Volume 2, Section 2). After testing the on-off ratio, a diagnostictrouble code (DTC) readout using the impulse counter scan tool mustalways be performed.b Diagnostic Manual Engines 08/00Notes regarding diagnostic trouble code (DTC) readout using theImpulse counter scan toolaWhen diagnosing engine running complaints, or when the CHECK-ENGINElamp is illuminated, the DTC memory should be read out and the DTC’snoted before any repairs are attempted. This will ensure that the techniciancan differentiate between actual malfunctions and “simulated malfunctions,”since testing done on a running engine will cause malfunctions to be storedthat were caused by a simulation or a disconnected circuit.When testing is completed, the DTC memory of the LH-SFI controlmodule, base module, DI control module and the EA/CC/ISC controlmodule or CC/ISC control module must be cleared.B 1 LH-SFI21/10
