Pinpoint Test B : U2002:47, U2002:96: Notes
WARNING: This page is about a different car, the 2018 Ford Edge. However, it is still accessible from the selected car via links, so may be relevant.
Refer to Vehicle Dynamic Systems for schematic and connector information.
Normal Operation and Fault Conditions
The parking brake switch has 3 positions; APPLY (pulled up), RELEASE (pushed down) and NEUTRAL. The ABS module sends voltage to the parking brake switch and this voltage returns along 1 of 3 circuits. An open, excessive resistance or a short in the parking brake switch circuits or the parking brake switch causes the ABS module to set a DTC.
DTC Fault Trigger Conditions
| DTC | Description | Fault Trigger Conditions |
|---|---|---|
| U2002:47 | Switch: Watchdog / Safety Failure | This DTC sets in continuous memory and on-demand if the test voltage sent to the parking brake switch from the ABS module does not return or returns along an incorrect path. |
| U2002:96 | Switch: Component Internal Failure | This DTC sets in continuous memory and on-demand if the parking brake switch is in the APPLY or RELEASE position for longer than 60 seconds while the vehicle is not moving. This DTC is also set if the voltage sent to the parking brake switch during an apply or release event does not return or returns along an incorrect path. |
