Pinpoint Test X: The Daytime Running Lamps (DRL) Are Inoperative: MKZ
WARNING: This page is about a different car, the 2009 Mercury Milan, 2009 Lincoln MKZ, and 2009 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.
When the ignition switch is in the RUN position, the headlamps are not on (from the autolamp system or manual control from the headlamp switch) and the transmission is not in PARK (P), the SJB provides voltage to the front turn lamps (on solidly, not flashing).
This pinpoint test is intended to diagnose the following:
- Exterior lighting system input/output
- Ignition switch input
- Parking brake switch input (manual transaxle)
- Transmission gear input (automatic transaxle)
- SJB
