Circuit Testing Tools

Do not use a test lamp in order to diagnose the Powertrain electrical systems unless specifically instructed by the diagnostic procedures. Use the
Connector Test Adapter Kit, J 35616 whenever diagnostic procedures call for probing any connectors.

NOTICE: Since the VCM is located under the hood, its connectors are sealed and cannot be backprobed as in the previous model years. Do not
attempt to backprobe as a connector or seal damage could occur.
