Wiper Activated Headlamps

The wiper activated headlamp function allows the headlamps and the 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. The windshield wiper switch must be activated for approximately 20 seconds. The instrument cluster receives a signal at the wiper ON input through CKT 91 (GRY) when the windshield wipers are activated for approximately 20 seconds. 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 the park lamps.

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