Retrieving Fault Codes

  1. Leave electrical connector attached to cruise control unit. Connect a 1.4-watt test light between terminals "D" and "F" of cruise control unit connector (backprobe connector). SeeFigure .
    NOTE: There is no wire in terminal "D" of cruise control unit connector. Push test light probe through connector cavity until probe contacts terminal on cruise control unit.
  2. Turn ignition on. Turn main switch to ON position. Ensure cruise indicator light comes on. If indicator light does not come on, repair it before continuing.
  3. Activate RESUME switch for at least 3 seconds. Test light will come on for 3 seconds, then go out for 2 seconds. After this, light will flash codes (if stored). See FAULT CODE DIRECTORY. If no fault codes are stored, light will not flash. To exit self-diagnostics, drive vehicle at a speed greater than 10 MPH or turn main switch to OFF position. Ensure light goes off.
