Wiper Activated Head Lamps

The wiper activated headlamps function allows the headlamps and park lamps to be activated by the windshield wipers. For this to occur, the ignition switch must be in the RUN position, the twilight sentinel must be enabled, and the windshield wiper switch must be activated for approximately 20 seconds. When the windshield wipers are activated for approximately 20 seconds, the instrument cluster receives a signal at the wiper on input via CKT 91 (GRY). In response to this input, the instrument cluster sends a request via the Class 2 serial data line to the PZM to activate the headlamps and park lamps.

The wiper activated headlamps feature can be disabled by either turning the windshield wiper switch off, the twilight sentinel off, or the ignition switch to the OFF position. If any one of these conditions occur, the wiper activated headlamps feature will be disabled. The wiper activated headlamps feature will override the Daytime Running Lamps (DRL), if active.
