Problem Symptoms Table: Notes

If a normal code is displayed during the DTC check but the trouble still occurs, check the circuits for each symptom in the order given in the matrix chart and perform the procedure given for troubleshooting. The matrix chart is divided into 3 chapters.

When troubleshooting, check CHAPTER 1: ELECTRICAL CIRCUIT  first. If instructed to proceed to CHAPTER 2: ON-VEHICLE REPAIR  or CHAPTER 3: OFF-VEHICLE REPAIR , proceed as instructed.

• If the instruction "Proceed to next circuit inspection shown on matrix chart" is given in the flow chart for each circuit, proceed to the circuit with the next highest number in the table to continue the check.
• If the trouble still occurs even though there are no abnormalities in any of the other circuits, then check and replace the ECM.
