    2. Using the scan tool, read the active DTCs.

      Does the scan tool display this DTC as active?

      Yes 

      • Go to step  2

      No 

  2. REMOTE START RELAY 
    1. Turn the ignition off.
      NOTE: Check the PDC fuses before continuing.
    2. Install a substitute relay in place of the original Remote Start Relay.
    3. Cycle the ignition switch from off to on, leaving the ignition on for a minimum of 90 seconds.
    4. Using the scan tool, read the active FCM DTCs.

      Does the scan tool display this DTC as active?
