P0604 - GM
Type: Powertrain Computer and Auxiliary Outputs - ISO/SAE Controlled
Description: Control Module Random Access Memory Fault Conditions
Cause: Key on for at least 5 seconds, system voltage over 10v, then the PCM detected that the internal data test (RAM) failed • Refer to code repair chart for instructions on how to replace a PCM and how to reprogram the replacement
This code is a fairly simple one. It basically means that the PCM/ECM (powertrain/engine control module) has detected an internal integrity fault in the PCM.
Hope this helps.
