DESCRIPTION

DTC Detection Condition:

The MG ECU monitors internal operations and detects a malfunction.

MONITOR DESCRIPTION

Monitor Strategy:

Typical Enabling Conditions:

Typical Malfunction Thresholds:

Component Operating Range:

The MG ECU performs many diagnostic tests to verify proper operation of internal ECU systems. In one of those diagnostics, the MG ECU checks the result of the motor CPU self-test. If the MG ECU detects a "Fail" from the motor CPU self-test, it will conclude that there is an internal malfunction in the motor CPU. The HV control ECU will illuminate the MIL and set a DTC.
