POWERTRAIN CONTROL MODULE (PCM)
|
Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding. (Refer to 28 - DTC-Based Diagnostics/MODULE, Powertrain Control (PCM)
- Standard Procedure).
1.
DTC IS ACTIVE
| 1. |
Ignition on, engine not running.
|
| 2. |
With the scan tool, erase DTCs in the PCM.
|
| 3. |
Monitor the scan tool for at least two minutes.
|
| 4. |
Cycle the ignition key off and on several times, leaving the ignition on for at least 10 seconds at a time.
|
| 6. |
Perform several engine run cycles, turning the ignition off for at least 20 seconds between each engine run cycle.
|
| 7. |
With the scan tool, select View DTCs.

Yes
No
3.
POWERTRAIN CONTROL MODULE
| 1. |
Using the wiring diagram/schematic as a guide, inspect the Powertrain Control Module wiring and connectors.
|
| 2. |
Look for any chafed, pierced, pinched, or partially broken wires.
|
| 3. |
Look for broken, bent, pushed out or corroded terminals.
|
| 4. |
Monitor the scan tool data relative to this circuit and wiggle test the wiring and connectors.
|
| 5. |
Look for the data to change or for the DTC to reset during the wiggle test.
|
| 6. |
Check for proper PCM power supply from the ignition switch and the ASD relay. Check the PCM for proper ground supply.
