DTC P0606 ECM / PCM ProcessorMONITOR DESCRIPTION
DTC Detection Condition:
Monitor Strategy:
Monitor Strategy:
Typical Malfunction Thresholds:
The ECM continuously monitors its own internal circuits. This self-checking ensures that the ECM is functioning properly.
The 2 CPUs, main and sub, inside the ECM perform continuous mutual monitoring. If the outputs from the 2 CPUs differ or deviate from the standard levels, the ECM determines that the internal circuits are malfunctioning. The ECM then illuminates the MIL and set the DTCs.
