TROUBLESHOOTING FAILURES WITHOUT FAULT CODES - Continued
MALFUNCTION
Engine Timing Incorrect.
CORRECTIVE ACTION
STEP 1.
Set Battery Disconnect Switch to ON. Set DEAD CRANK SWITCH to NORMAL.
Turn the ENGINE CONTROL switch to COOL DOWN/STOP.
STEP 2.
Verify engine speed during cranking using GSC readout of engine speed.
a.
If speed is not greater than 50 rpm during cranking, perform load test on
batteries. Check batteries and cables as required. Replace as required
b.
STEP 3.
Inspect and adjust engine timing sensors.
a.
Inspect sensors and adjust if good (WP 0013, SYMPTOM 3).
b.
If sensors are damaged, replace/adjust sensors (WP 0013, SYMPTOM
3).
STEP 4.
Perform Engine Timing Sensor Calibration (WP 0013, SYMPTOM 8). Replace
STEP 5.
Verify the problem has been resolved.
MALFUNCTION
Personality Module Mismatch.
CORRECTIVE ACTION
STEP 1.
On EMCP set ENGINE CONTROL switch to OFF/RESET. Set Battery
Disconnect Switch to OFF. Set DEAD CRANK SWITCH to OFF.
STEP 2.
Check for correct installation of ECM to EMCP harness connector ENG-P1 to
ECM J1 and of engine harness connector ENG-P1 to ECM J2 (cables plugged in
to ECM) (FO-2, sheet 1 and sheet 2) and (WP 0088), Figure 2, sheet 3). Plug
connectors in securely.
STEP 3.
Check engine harness timing sensor connectors ENG-P401 and ENG-P402 and
unit injector connector ENG-P300/J300. Plug connectors in securely.
STEP 4.
Verify that CID 253 FMI 02 personality module mismatch is not displayed on the
GSC. If the ECM has a problem with the internal personality module, the engine
will crank, but will not start. Replace ECM (WP 0082).
STEP 5.
Verify the problem has been resolved.
