Internal Control Module KAM (Keep Alive Memory) Error
The PCM has detected an internal memory error.
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 engine control module (PCM) stores important data like sensor calibrations and settings. If it can't access or save this data properly, it triggers a fault code like P0613.
What the computer is actually seeing
The PCM monitors its own internal memory status. An error is logged when it detects a fault with writing to or reading from the Keep Alive Memory, often resulting in a check engine light and potential limp mode.
What a healthy reading looks like
The PCM expects data integrity for all stored settings, typically accessing its memory without fault when the ignition is on.
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. Inspect the battery voltage. It should be between 12.4V and 12.7V with the engine off.
- 22. Check the vehicle's wiring harness and connectors leading to the PCM for damage or corrosion.
- 33. Look for signs of water intrusion in the PCM area. Repair any external damage that could cause shorting.
- 44. Test the PCM using a capable scan tool for any additional codes that may indicate related failures.
- 55. If voltages and connections are good, consider testing power and ground circuits to the PCM. Ensure power supply voltage is 5V-12V depending on vehicle specifications.
- 66. If all previous steps are clear, replace the PCM and reprogram if necessary, ensuring to restore proper calibration settings.
Common causes
- Faulty PCM
- Corroded or damaged connectors
- Power supply issues to the PCM
- Wiring issues
- Recent vehicle electrical work or modifications
