Normal Operation

WARNING: This page is about a different car, the 2010 Mercury Mariner and 2010 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.

The ABS module uses input from the brake pedal angle sensor to determine the amount of deceleration the driver is requesting. The brake pedal angle sensor utilizes 2 Hall-effect sensors that provide redundant signals indicating the position of the brake pedal. Brake pedal angle sensor 1 provides signal to the ABS module along circuit VCA43 (WH/GN). Brake pedal angle sensor 2 provides signal to the ABS module along circuit VCA30 (YE/VT). The ABS module provides a 5-volt reverence voltage used by both of the sensors along circuit LCA27 (BN/WH). The ABS module provides a signal return common to both sensors along circuit RCA27 (WH).

DTC FAULT TRIGGER CONDITIONS CHART

DTC Description Fault Trigger Conditions
  • C100A:62 - Brake Pedal Angle Sensor: Signal Compare Failure
 This DTC will set if 1 of the 2 sensors inside the brake pedal angle sensor is inconsistent with the other or if the ABS module is faulted internally. This DTC can set as a result of other DTCs indicating a brake pedal angle sensor circuit fault. If DTCs C100D:21, 22 or C100E:21, 22 are present along with this DTC, diagnose them first.
  • C100D:21 - Brake Pedal Angle Sensor Circuit 1: Signal Amplitude □ Minimum
 If the voltage on circuit VCA43 (WH/GN) is less than 300 millivolts, or if the ABS module is faulted internally, this DTC can set. This DTC can set as a result of a brake pedal sensor supply or signal return circuit fault. Diagnose DTC C100F:11 or 12 first if it is retrieved along with this DTC.
  • C100D:22 - Brake Pedal Angle Sensor Circuit 1: Signal Amplitude > Maximum
 If the voltage on circuit VCA43 (WH/GN) is greater than 4.72 volts, this DTC can set. This DTC can set as a result of a brake pedal angle sensor supply or signal return circuit fault, an internal brake pedal angle sensor fault or an internal ABS module fault. Diagnose DTC C100F:11 or 12 first if it is retrieved along with this DTC.
  • C100E:21 - Brake Pedal Angle Sensor Circuit 2: Signal Amplitude □ Minimum
 If the voltage on circuit VCA30 (YE/VT) is less than 300 millivolts, this DTC can set. This DTC can set as a result of a brake pedal angle sensor supply or signal return circuit fault, an internal brake pedal angle sensor fault or an internal ABS module fault. Diagnose DTC C100F:11 or 12 first if it is retrieved along with this DTC.
  • C100E:22 - Brake Pedal Angle Sensor Circuit 2: Signal Amplitude > Maximum
 If the voltage on circuit VCA30 (YE/VT) is greater than 4.72 volts, this DTC can set. This DTC can set as a result of a brake pedal angle sensor supply or signal return circuit fault, an internal brake pedal angle sensor fault or an internal ABS module fault. Diagnose DTC C100F:11 or 12 first if it is retrieved along with this DTC.
  • C100F:11 - Brake Pedal Angle Sensor Supply: Circuit Short To Ground
 If circuit LCA27 (BN/WH) is shorted to ground, this DTC will set. The ABS module supplies power to both of the sensors inside the brake pedal angle sensor along circuit LCA27 (BN/WH). If circuit LCA27 (BN/WH) is shorted, brake pedal angle sensor signal fault DTCs will set for both of the sensors. Correct this DTC before diagnosing DTCs C100D:21, 22 or C100E:21, 22.
  • C100F:12 - Brake Pedal Angle Sensor Supply: Circuit Short To Battery
 If circuit LCA27 (BN/WH) is shorted to voltage, this DTC will set. The ABS module supplies power to both of the sensors inside the brake pedal angle sensor along circuit LCA27 (BN/WH). If circuit LCA27 (BN/WH) is shorted, brake pedal angle sensor signal fault DTCs will set for both of the sensors. Correct this DTC before diagnosing DTCs C100D:21, 22 or C100E:21, 22.
