The Controller Diagnostic receives data from several self-diagnosing devices onboard the powertrain control module. Conditions which are detected include supply voltage out of limits, acceptable temperature exceeded, low-power counter clock failure, and general device fault.
Checking PCM under detecting condition, if internal error is detected, PCM sets P0606. And MIL(Malfunction Indication Lamp) turns on.
Item | Detecting Condition | Possible cause |
DTC Strategy | ● Check PCM internal error | ● Faulty PCM |
Enable Conditions | ● 7V< Battery voltage< 20V | |
Threshold value | ● PCM internal error (A/D unit error) | |
Diagnosis Time | ● Continuous | |
MIL On Condition | ● 1 driving cycle |
