Use of Circuit Testing Tools
NOTE: 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.
IMPORTANT: Do not use a test lamp in order to diagnose the control module system unless specifically instructed by the diagnostic procedures. Use the J 35616-A connector test adapter kit whenever the diagnostic procedure instructs the technician to probe any of the connectors.
