Good afternoon,
The 601 is troubling. It detects a possible PCM or TCM failure.
Description
This diagnostic applies to internal microprocessor integrity conditions within the power-train control module (PCM). This diagnostic also addresses if the PCM is not programmed.
DTC Descriptors
This diagnostic procedure supports the following DTCs:
- DTC P0601 Control Module Read Only Memory (ROM)
- DTC P0602 Control Module Not Programmed
- DTC P0603 Control Module Long Term Memory Reset
- DTC P0604 Control Module Random Access Memory (RAM)
- DTC P0606 Control Module Internal Performance
- DTC P0607 Control Module Performance
- DTC P060E Control Module Throttle Position (TP) System Performance
- DTC P062F Long Term Memory Performance
- DTC P2610 Ignition Off Timer Performance
I attached possible failures below that need to be checked.
Was there any issues prior to this repair?
