TROUBLESHOOTING USING GSC FAULT CODES - Continued
CORRECTIVE ACTION - Continued
STEP 8.
Set Battery Disconnect Switch to ON, Set DEAD CRANK SWITCH to NORMAL.
Turn ENGINE CONTROL switch to COOL DOWN/STOP. Disconnect the
following sensors one at a time, while observing the GSC (WP 0090, Figure 1).
a. Engine oil pressure sensor.
b. Turbo outlet pressure sensor.
c.
Fuel pressure sensor.
d. Injection actuation pressure sensor.
e. Atmospheric pressure sensor.
f.
Turbo inlet pressure sensor.
STEP 9.
On EMCP, turn ENGINE CONTROL switch to OFF/RESET, Battery Disconnect
Switch to OFF; and DEAD CRANK SWITCH to OFF.
STEP 10.
If the diagnostic code deactivated after a particular sensor was disconnected,
replace the sensor causing the fault. Reconnect sensors.
STEP 11.
Set Battery Disconnect Switch to ON, Set DEAD CRANK SWITCH to NORMAL.
Turn ENGINE CONTROL switch to COOL DOWN/STOP. Verify if problem still
exists.
a. If faults still exist and not all the sensors have been disconnected; go back to
STEP 8.
b. If all sensors have been disconnected and fault remains active, go to STEP
12.
STEP 12.
Turn the ENGINE CONTROL switch to OFF/RESET. Battery Disconnect Switch
is OFF; DEAD CRANK SWITCH is OFF.
STEP 13.
If STEP 7 was not performed earlier, Troubleshooting wiring harness per STEP
7, (a), (b), (d), and (e).
STEP 14.
Set Battery Disconnect Switch to ON, Set DEAD CRANK SWITCH to NORMAL.
Turn ENGINE CONTROL switch to COOL DOWN/STOP. Check for fault code.
If the fault code has not cleared, continue to STEP 15. If the fault code has
cleared, the problem has been resolved.
STEP 15.
If problem still exists, replace the ECM (WP 0084).
STEP 16.
Set Battery Disconnect Switch to ON, Set DEAD CRANK SWITCH to NORMAL.
Turn ENGINE CONTROL switch to COOL DOWN/STOP. Verify fault code has
cleared.
