Control Module Internal Permanent Memory Failure
The control module has detected a memory failure.
Heads up: this code wasn't in our hand-written library yet, so DiagCoach AI built this page on the fly. Double-check critical specs against service info before condemning parts.
What it means (plain English)
The computer's memory is malfunctioning, which can affect how it processes data and controls systems in the vehicle.
What the computer is actually seeing
The control module recognizes an issue in its internal memory, causing it to be unable to store or retrieve data correctly.
What a healthy reading looks like
No specific voltage or pressure, but the module typically should have normal operational parameters when functioning properly.
Guided diagnostic — the DiagCoach way
Don't just throw parts at it. Walk through these in order — each step tells you whether to keep going or stop and fix what you found.
- 11. Check the battery voltage; it should be between 12.5V to 14.5V. If it's low, charge or replace the battery. Decision point: If battery voltage is low, resolve issue.
- 22. Inspect the wiring and connectors on the control module for corrosion or damage. Repair any issues found. Decision point: If repair brings system back to normal, clear codes and test drive.
- 33. Use a scan tool to check for software updates for the control module. If an update is available, follow the manufacturer's procedure to update it. Decision point: If updating resolves the issue, monitor for reoccurrence.
- 44. If the issue persists after repairs and updates, consider swapping the control module with a known good unit. If the new module clears the code, the original module is faulty.
Common causes
- Corrupted software in the control module
- Faulty control module hardware
- Electrical interference affecting the module
Typical repair cost
