DTC 36

DTC 36 Missing Vehicle Speed Sensor Signal






Circuit Description

A DTC 36 relates to the BPMV losing the VSS buffer 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 set by a faulty VSS, VSS buffer or circuit conditions in CKTs 696, 821, and 822. Do not replace the BPMV for this DTC. A faulty BPMV will not cause this DTC to set.

Test Description

- Measure the resistance of the VSS.
- Measure the resistance of CKT 822.
- Check the voltage applied to the BPMV through CKT 696.
- Check the connections in the VSS and VSS buffer circuits.

Diagnostic Aids

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

If the voltage readings are low or varying, the battery, charging system or intermittent connections could be the cause. Check these areas before replacing any components.

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.
