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.
