Antilock Braking System (ABS)

Circuit Description

A DTC 35 relates to an open condition in the left rear wheel speed sensor or Circuit This DTC is a soft fault and sets when the vehicle is at zero mph. The BPMV checks for the proper resistance in the left rear wheel speed sensor circuit Any condition that creates excessive resistance or an open condition in the left rear speed sensor circuit can cause this DTC to set. Do not replace the BPMV for this DTC. A faulty BPMV will not cause this DTC to set.

Test Description

- Check BPMV 8-way connector pins D and E for looseness, corrosion, etc.
- Measure the resistance of BPMV 8-way connector pins D and E.
- Measure resistance at the left rear speed sensor connector.
- Check speed sensor output using the Tech 1.
- Check for intermittent opens in CKTs 884 and 885.

Diagnostic Aids

Do not replace the BPMV for this DTC. A faulty BPMV will not cause this DTC to set.

This DTC can only be set by a malfunction in the left rear wheel speed sensor and circuit.

This DTC can be caused by someone disconnecting one or more speed sensors to get the wiring out of the way while doing brake or suspension repairs and then forgetting to plug the connectors back together.

Do not pierce the electrical connectors, wires, seals, or insulation during testing. Doing so will break the seal and lead to corrosion and failure of the wiring and terminals.
