P0601 on Chrysler
Internal Control Module Memory Check Sum Error
P0601 on Chrysler vehicles indicates internal control module memory check sum error. Au7o has documented this code across 1 Chrysler model — most commonly on Prowler. The control module ran an internal self-check (checksum) on its memory and the calculated value did not match the stored value, indicating corrupted or failed internal memory. It is an internal module integrity fault. Typical repair costs on Chrysler range from $300 to $1,200, depending on the specific model and root cause.
Common Causes of P0601
- •Corrupted or failed internal PCM/ECM memory
- •Faulty/aborted software reflash or programming
- •Low or unstable battery/system voltage during operation
- •Corroded PCM ground or power connectors
- •Defective control module
P0601 on Chrysler by Model
Chrysler Prowler(1 issue)
- PCM Internal Checksum Failure (P0601) / Obsolete Engine Computer1997-2002
The engine PCM (Powertrain Control Module) suffers an internal memory-chip failure that sets code P0601 'Internal Control Module Check-Sum Error' and illuminates the Check Engine Light, which also causes the car to fail most state inspections. If ignored, the PCM progressively degrades and can fail completely, leaving the car stranded. Because the Prowler's PCM is a low-volume, long-out-of-production unit, replacement is a documented ownership headache.
