Diagnostic Aids

Check for the following conditions if a history or intermittent DTC is indicated.

A poor connection at the SSPS control module. Inspect the harness connectors for backed out terminals, improper mating, improperly formed or damaged terminals, and poor terminal to wire connections.
A damaged wiring harness. Inspect the wiring harness for damages. If the wiring harness appears to be in good condition, observe the display on the DMM while moving the connectors and wiring harnesses related to the actuator. A change in the DMM display during the test will indicate the location of the fault.
