Pinpoint Test Purpose

To verify the PSCM wiring harness and connectors are OK. This test checks the connectors and wiring from the PSCM 3-pin connector at the steering gear to the in-line connector in the engine compartment. If these circuits are working correctly, the test then directs to check the ABS module and wiring harness.
