Power Door Lock Relay: Description and Operation
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 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.
