IPDM E/R (INTELLIGENT POWER DISTRIBUTION MODULE ENGINE ROOM)


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 tail and parking 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.
