Checking wiring and sensors
Check the wiring between the pedal pressure sensor:
- terminal #1 and control module terminal #13 (terminal #A13)
- terminal #2 and control module terminal #29 (terminal #A29)
- terminal #5 and control module terminal #32 (terminal #A32).
Check for an open-circuit, a short-circuit to ground and a short-circuit to supply voltage. Continue with the following check if no fault is found.
Checking the pedal pressure sensor
- Ignition on
- Connect the breakout box to the wiring (not to the ABS control module).
Check the pedal pressure sensor. Measure the resistance between terminals #A13 and #A32 on the breakout box.
When the brake pedal is not depressed the resistance must be infinite.
When the brake pedal is depressed the resistance must be 0 Ω.
Also check the resistance between terminals #A29 and #A32 on the breakout box.
When the brake pedal is unaffected, the resistance must be 0 Ω.
When the brake pedal is depressed the resistance must be infinite.
Remedy as necessary.
