Function of Detecting Ignition Relay Malfunction

Function of Detecting Ignition Relay Malfunction
- When the integrated ignition relay is stuck in a "closed contact" position and cannot be turned OFF, IPDM E/R turns ON tail and parking lamps for 10 minutes to indicate IPDM E/R malfunction.




- When the state of the integrated ignition relay does not agree with the state of the ignition switch signal received via CAN communication, the IPDM E/R activates the tail lamp relay.

NOTE: When the ignition switch is turned ON, the tail lamps are OFF.
