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.
