Tech Tips


  • Use the table below to help determine the cause of problem symptoms. If multiple suspected areas are listed, the potential causes of the symptoms are listed in order of probability in the "Suspected Area" column of the table. Check each symptom by checking the suspected areas in the order they are listed. Replace parts as necessary.

  • Inspect the fuses and relays related to this system before inspecting the suspected areas below.

  • The Matrix Chart is divided into 3 chapters.

    Chapter 1:

    Refer to the table below when the cause of the trouble is considered to be electrical.

  • If the instruction "Proceed To Next Suspected Area Shown In Problem Symptoms Table" is given in the flowchart of a circuit, proceed to the next suspected area in the table to continue the check.

  • If the trouble still occurs even though there are no abnormalities in any of the other circuits, check the ECM and replace it if necessary.

  • *: When the circuit is defective, a DTC may be output.
