P0606

2AZ-FXE ENGINE CONTROL: SFI SYSTEM: P0606: ECM / PCM Processor
P0606 - ECM / PCM Processor

MONITOR DESCRIPTION

The hybrid vehicle control ECU continuously monitors its main and sub CPUs. This self-check ensures that the hybrid vehicle control ECU is functioning properly. If outputs from the CPUs are different and deviate from the standards, the hybrid vehicle control ECU will illuminate the MIL and set the DTC immediately.
