Monitor Description

WARNING: This page is about a different variant/trim than selected.

The hybrid vehicle control ECU performs many diagnostic tests to verify proper operation of internal ECU systems. One of these tests checks for errors after a memory read/write diagnostic test. If the hybrid vehicle control ECU detects this malfunction inside the ECU, it will illuminate the MIL and set a DTC.
