RELAY CONTROL SYSTEM

*: With daytime running light system

IPDM E/R activates the internal control circuit to perform the relay ON‐OFF control according to the input signals from various sensors and the request signals received from control units via CAN communication.

■ CAUTION ■

IPDM E/R integrated relays cannot be removed.

NOTE：

BCM controls the starter relay.
