Diagnostic Procedure

Step

Inspection

Action

1

RECORD THE CAR CONFIGURATION DATA

•  Switch the ignition ON (engine off) and wait for 6 s or more.

•  Switch the ignition off.

•  Switch the ignition ON (engine off).

Go to the next step.

2

VERIFY THAT THE SAME DTC IS NOT PRESENT

•  Clear the DTCs from the memory.
(See CLEARING DTC [AUDIO AMPLIFIER].)

•  Perform the audio amplifier DTC inspection using the M-MDS.
(See DTC INSPECTION [AUDIO AMPLIFIER].)

•  Are the same DTCs present?

Yes

Repeat the inspection from Step 1.

If the malfunction recurs, go to the next step.

No

Go to Step 5.

3

INSPECT FOR INSTRUMENT CLUSTER MALFUNCTION

•  Switch the ignition off.

•  Perform the instrument cluster DTC inspection using the M-MDS.
(See DTC INSPECTION [INSTRUMENT CLUSTER].)

•  Are any DTCs present?

Yes

Go to applicable DTC inspection.

(See DTC TABLE [INSTRUMENT CLUSTER].)

After repairing the instrument cluster, perform the instrument cluster configuration.

(See INSTRUMENT CLUSTER CONFIGURATION (USING AS-BUILT DATA).)

Then go to the next step.

No

Go to the next step.

4

VERIFY THAT THE SAME DTC IS NOT PRESENT

•  Clear the DTCs from the memory.
(See CLEARING DTC [AUDIO AMPLIFIER].)

•  Perform the audio amplifier DTC inspection using the M-MDS.
(See DTC INSPECTION [AUDIO AMPLIFIER].)

•  Are the same DTCs present?

Yes

Repeat the inspection from Step 1.

•  If the malfunction does not recur, go to the next step.

•  If the malfunction recurs, replace the audio amplifier. (See AUDIO AMPLIFIER REMOVAL/INSTALLATION.)

Go to the next step.

No

Go to the next step.

5

VERIFY THAT NO OTHER DTCs ARE PRESENT

•  Verify other DTCs displayed.

•  Are any other DTCs output?

Yes

Perform the corresponding DTC inspection.

No

DTC troubleshooting completed.
