WARNING: This page is about a different car, the 2014 Mitsubishi Outlander. However, it is still accessible from the selected car via links, so may be relevant.

Use these steps to plan your diagnostic strategy. If you follow them carefully, you will check most of the possible causes of a cruise control system malfunction.

  1. Gather information from the customer.
  2. Verify that the condition described by the customer exists.
  3. Check the vehicle for any cruise control system DTC. (Refer to CRUISE CONTROL SYSTEM DIAGNOSIS  Diagnostic Function - How to Read Diagnostic Trouble Codes).
  4. If you can verify the condition but no cruise control system DTCs are stored, the malfunction may be intermittent. (Refer to HOW TO COPE WITH INTERMITTENT MALFUNCTIONS ).
  5. If you can verify the condition but there are no cruise control system DTCs, find the fault. (Refer to CHECK CHART FOR TROUBLE SYMPTOMS  Symptom Chart).
  6. If there is a cruise control system DTC, record the number of the code, then erase the code. (Refer to CRUISE CONTROL SYSTEM DIAGNOSIS  Diagnostic Function - How to Erase Diagnostic Trouble Codes).
  7. Re-create the cruise control system DTC stored conditions to see if the same cruise control system DTC will stored again. (Refer to CRUISE CONTROL SYSTEM DIAGNOSIS  Diagnostic Function - How to Read Diagnostic Trouble Codes).
    • If the same cruise control system DTC sets again, perform the diagnostic procedures for the set code. (Refer to CHECK CHART FOR TROUBLE SYMPTOMS  Diagnostic Trouble Code Chart).
