DTC P0601: INTERNAL CONTROLLER FAILURE
Monitored & Set Conditions
Internal controller operation is monitored when ignition is on. DTC will be stored in Powertrain Control Module (PCM) memory when an internal checksum for software failed and does not match the calculated value. Possible cause for DTC to set is a defective PCM.
Turn ignition on. Using scan tool, check for DTCs. If DTC P0601: INTERNAL CONTROLLER FAILURE does not exist, test is complete. If DTC P0601: INTERNAL CONTROLLER FAILURE exists, replace PCM. PCM is located on left side of engine compartment, near front of battery. Program the new PCM.
