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 IPDM E/R 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.
NOTE: When the ignition switch is turned ON the tail lamp is OFF.
