Diagnostic Test

  1. CHECK FOR AN ACTIVE DIAGNOSTIC TROUBLE CODE (DTC) 
    NOTE:

    Before proceeding with this diagnostic procedure, verify the Left and Right Multifunction Switch and Clockspring harness connectors are properly seated and verify proper pin terminal tension. A loose connection at any of these connectors may cause this DTC to set.

    1. Turn the ignition on.
    2. With the scan tool, read DTCs.

      Does the scan tool display this DTC as active?

      Yes 

      • Go To  2

      No 

      • Test complete, the condition or conditions that originally set this DTC are not present at this time. Using the wiring diagrams as a guide, check all related splices and connectors for signs of water intrusion, corrosion, pushed out or bent terminals, and correct pin tension.
  2. CHECK THE VOLTAGE OF (D506) LIN BUS CIRCUIT AT THE RIGHT STEERING WHEEL SWITCH (SPEED CONTROL SWITCH)
