DTC 36

Circuit Description

A DTC 36 relates to the BPMV losing the left rear wheel speed sensor signal for at least 5 seconds at speeds over 8 mph with the brake pedal released. If a DTC 35 is also stored, use that diagnostic chart. This DTC can be caused by a faulty sensor, tone wheel, or a circuit condition. Do not replace the BPMV for this DTC. A faulty BPMV will not cause this DTC to set.

Test Description

- Check for speed output from the left rear speed sensor using the Tech 1.
- 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.
- Check connections at the left rear speed sensor connector.
- Measure resistance at the left rear speed sensor connector.
- Check wiring harness for chafing.
- Check if intermittent condition requires replacing the left rear speed sensor or harness.

Diagnostic Aids

If a DTC 35 is also stored, refer to that diagnostic chart. If this DTC occurs on ice, check for brake drag or frozen brake components.

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.

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.
