Function of Detecting Ignition Relay Malfunction
- When contact point of integrated ignition relay is stuck and cannot be turned OFF, IPDM E/R turns ON parking, license plate, side marker and tail lamps for 10 minutes to indicate ignition relay malfunction.
- When a state of ignition relay having built-in does not agree with a state of ignition switch signal input by a CAN communication from BCM, IPDM E/R lets tail lamp relay operate.
