Driver unlock relay. Headlamp relay

Driver unlock relay

The driver unlock relay is a International Standards Organization (ISO) micro-relay. The terminal designations and functions are the same as a conventional ISO relay. However, the micro-relay terminal orientation (or footprint) is different, current capacity is lower, and the relay case dimensions are smaller than those of the conventional ISO relay.

The driver unlock relay is a electromechanical device that switches battery current to the left front door power lock motor when the Remote Keyless Entry (RKE) receiver within the high-line Central Timer Module (CTM) grounds the relay coil. See Driver Unlock Relay in the Diagnosis and Testing section of this group for more information.

The driver unlock relay is located in the relay and fuse block attached to the back of the junction block, under the left side of the instrument panel in the passenger compartment. The driver unlock relay cannot be repaired and, if faulty or damaged, it must be replaced.

Headlamp relay

The headlamp (or security) relay is a International Standards Organization (ISO) micro-relay. The terminal designations and functions are the same as a conventional ISO relay. However, the micro-relay terminal orientation (or footprint) is different, current capacity is lower, and the relay case dimensions are smaller than those of the conventional ISO relay.

The headlamp relay is a electromechanical device that switches battery current to the headlamps when the high-line Central Timer Module (CTM) grounds the relay coil. See Headlamp Relay in the Diagnosis and Testing section of this group for more information.

The headlamp relay is located in the Power Distribution Center (PDC), behind the battery on the left side of the engine compartment.

The headlamp relay cannot be repaired and, if faulty or damaged, it must be replaced.
