WHEN MONITORED
Ignition on.
SET CONDITION
Internal PCM failure. Customer may experience an extended cranking condition with limited driving and a rough idle. One trip fault and the code will set within 5 seconds. ETC light is flashing.
POSSIBLE CAUSES
- Powertrain control module needs to be reprogrammed
Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding.
Diagnostic Test
1. REPROGRAM THE POWERTRAIN CONTROL MODULE
Check for any related TSBs.
Verify the PCM is at the latest calibration (flash level).
NOTE:
- Inspect the Intake Manifold components for vacuum leaks, repair as necessary
- An intermittent loss of power to the PCM without performing an ETC Relearn procedure may cause this DTC to set.
- Diagnose any other DTCs that may have set with the P2108.
Flash the Powertrain Control Module if any updates are available.
Start the engine.
Allow the engine to reach normal operating temperature.
Operate the accelerator pedal. (do not exceed 3500 rpm)
Test drive the vehicle for 10 miles on a flat road surface.
Q: Does this DTC reset by itself?
YES: Replace and reprogram the Powertrain Control Module. Perform the POWERTRAIN VERIFICATION TEST. Powertrain Verification Test
NO: Test Complete.
