TROUBLESHOOTING USING GSC FAULT CODES - Continued
CORRECTIVE ACTION
STEP 1.
Inspect wiring at ECM connector J2.
a. Repair or replace wiring, as required (WP 0090).
b. If wiring is not defective, replace ECM (WP 0084).
STEP 2.
Verify the problem is resolved.
SYMPTOM
9.
CID 42 E FMI 11
MALFUNCTION
Injection actuator pressure valve.
FMI 11 - Failure Mode is not Identifiable (Mechanical Failure).
CORRECTIVE ACTION
STEP 1.
On EMCP, turn ENGINE CONTROL switch to OFF/RESET. Battery Disconnect
Switch is OFF; DEAD CRANK SWITCH is OFF.
STEP 2.
Inspect connectors ENG-P2 and ENG-P3 on engine harness (FO-2, sheet 1).
STEP 3.
Conduct an appropriate pull test on the wires in the ENG-P2 and ENG-P3
connectors to ensure the wires are tight and secure.
STEP 4.
Check the wires on the engine harness for abrasion and pinch points (WP 0090).
Repair and/or replace the connectors and/or wiring (WP 0090), as necessary.
STEP 5.
Verify the problem is resolved.
STEP 6.
If not, disconnect engine harness connector ENG-P3 from injection actuation
pressure (IAP) control valve connector (WP 0090 Figure 1, sheet 1, and FO-2,
sheet 1).
STEP 7.
Measure resistance between pins of IAP control valve connector (WP 0090, Fig-
ure 2, sheet 2). Measurement should be between 6.5 and 10.5 ohms. Record
the value.
If the resistance is not between 6.5 and 10.5 ohms, replace IAP control valve
STEP 8.
Reconnect ENG-P3 to IAP control valve connector.
STEP 9.
Verify the problem is resolved.
STEP 10.
If not, disconnect P2 of engine harness (FO-2, Sheet 1) from ECM.
STEP 11.
Measure resistance between terminals ENG-P2-61 (IAPCV signal) and ENG-P2-
62 (IAPCV return). Resistance should be within two (2) ohms of the value
measured in TEST STEP 6. Repair and/or replace the connectors and/or wiring
STEP 12.
If not, disconnect engine harness connector ENG-P3 from IAP control valve
connector.
