Circuit/System Verification

  1. Inspect all available vehicle keys that they are correct vehicle keys.
    • If not a correct vehicle key, replace the key.
  2. While viewing the scan tool BCM Key Part Number, turn ON the ignition with each of the available vehicle keys. The parameter should display a Key Part Number for all available keys.
    • If any key results in the parameter not reading a Key Part Number, replace the appropriate key.
