Headlamp Relay: Description and Operation
SYSTEM OPERATION
The headlamp 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 for more information.
The headlamp relay is located in the junction block, behind the fuse access panel on the left outboard end of the instrument panel, in the passenger
compartment.
The headlamp relay cannot be repaired and, if faulty or damaged, it must be replaced.
