Test I: DTC C1287 - Brake Booster Pedal Force Switch Circuit Failure

Pinpoint Test I: DTC C1287 - Brake Booster Pedal Force Switch Circuit Failure
Refer to Vehicle/Diagrams, Vehicle Dynamic Systems for schematic and connector information.

Normal Operation
The active brake booster has a normally open and a normally closed pedal force switch that operates according to driver brake applications.

In the normally open position, the brake booster pedal force switch connects circuit CCA29 (GN/BU) to circuit CCA25 (VT/GY). In the normally closed position, the switch connects circuit CCA29 (GN/BU) to circuit CCA26 (BU/GY).
^ DTC C1287 Brake Booster Pedal Force Switch Circuit Failure - If the ABS module detects an open, a short to voltage or a short to ground on the booster pedal force switch circuits, or if the switch input does not agree with other brake pedal inputs, DTC C1285 will be set.

This pinpoint test is intended to diagnose the following:
^ Wiring, terminals or connectors
^ Active brake booster
^ ABS module
