Pinpoint Test I : The Electronic Park Brake Fault Indicator Is Never Or Always On: Notes
WARNING: This page is about a different car, the 2018 Lincoln Navigator. However, it is still accessible from the selected car via links, so may be relevant.
The Electronic Park Brake Fault Indicator Is Never or Always On
Normal Operation and Fault Conditions
See Electronic Park Brake Fault Indicator and ABS/Brake/Stability-Traction Control System Indication. Refer to: Instrument Panel Cluster (IPC) - System Operation and Component Description .
NOTE:
The electric park brake indicator only illuminates or flashes when a parking brake system or ABS fault is detected. The indicator is off under all other conditions.
If the parking brake (yellow) indicator request is missing for less than 5 seconds, the IPC defaults the electronic park brake fault indicator to its last indication state (on or off), based upon the last message received.
If the parking brake (yellow) indicator request is missing for 5 seconds or longer, the IPC defaults the electronic park brake fault indicator on.
