C0035 reports a fault in the feed that powers the right front active wheel speed sensor, the right-hand partner of C0032. The ABS/ESC module supplies the sensor with a regulated voltage; an open feed, a short to ground or to another voltage, or a supply outside its window leaves the sensor unable to send a speed signal. NHTSA's EPS safety report lists C0035 with this meaning in its table of J2012 wheel speed codes. Caution with older GM vehicles: GM numbers its four wheel speed sensor circuits C0035 to C0050 in its own scheme (bulletin 16-NA-248, PIE0456), so a GM C0035 is a sensor circuit fault rather than a supply fault. ABS, traction and stability control switch off and the ABS lamp lights; normal braking remains.

Likely causes

Open or shorted supply wire to the right front sensor
Corroded or loose sensor connector
Sensor shorted internally and pulling the supply down
Sensor supply output of the ABS module faulty

Symptoms

  • ABS warning lamp on
  • ABS, traction and stability control disabled
  • No speed signal from the right front wheel
