DTC 68

Circuit Description

DTCs 67 and 68 relate to the pump motor and circuit in the BPMV. The motor and pumps are integral with the BPMV and cannot be serviced. The BPMV must be replaced if these tests show the motor or internal circuitry have failed. These DTCs can be caused by poor power and ground at the 2-way connector or motor harness on the BPMV.

TEST DESCRIPTION:

- Check the voltage and ground circuits at the BPMV 2-way connector.
- Check the motor harness and Connector for damage.
- Check CKT 150 for a good ground.
- Check if DTC returns after being cleared.

Diagnostic Aids

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.
