Circuit/System Verification

NOTE: If the condition is intermittent or cannot be duplicated, disconnect the connectors and add Nyogel lubricant 760G. This procedure will correct the high resistance condition due to terminal fretting corrosion.
  1. Engine running, transmission in R.
  2. Verify a clear rear vision image is displayed on the P17 Info Display Module.
    • If a clear image is not displayed 

      Refer to Circuit/System Testing.

    • If a clear image is displayed 
  3. All OK.
