Internal Control Module Software Incompatibility
A control module has detected that its own internal software version is inconsistent — for example a partial flash that left the module with mismatched calibration and program code. The module may go offline or operate in a fallback mode.
Affected components
- Control module
Common causes
- High likelihood: Incomplete or interrupted module flash
- Medium likelihood: Corrupted calibration block
- Low likelihood: Gateway module routing CAN messages incorrectly
Possible symptoms
- Multiple warning lights may illuminate
- Affected modules may go into limp mode or shut down
- Specific functions inoperative depending on module
- Diagnostic tools may show communication faults
Diagnostic notes
- The malfunction indicator lamp may illuminate
