Possible cause

NOTE:

• To correctly write the configuration data sent from the instrument cluster to the audio amplifier to the audio amplifier, 30 s or more need to have elapsed since the ignition was switched ON (engine off or on).

• Instrument cluster configuration is not completed.

• Module configuration procedure was not completed properly

• Correct data cannot be received from instrument cluster

• Instrument cluster malfunction

• Audio amplifier malfunction

Step

Inspection

Action

1

• Retrieve the instrument cluster DTCs using the M-MDS.

  (See DTC INSPECTION [INSTRUMENT CLUSTER].)

• Are any DTCs displayed?

Yes

Repair or replace the malfunctioning part according to the applicable DTC troubleshooting.

(See DTC TABLE [INSTRUMENT CLUSTER].)

No

Go to the next step.

2

• Clear the DTC for the audio amplifier using the M-MDS.

  (See CLEARING DTC [AUDIO AMPLIFIER].)

• Switch the ignition ON (engine off or on) and wait for 30 s or more.

• Perform a CMDTC self-test using the M-MDS.

  (See DTC INSPECTION [AUDIO AMPLIFIER].)

• Are there any modules other than the audio amplifier displaying the same DTC?

Yes

Using the M-MDS, perform the instrument cluster configuration (using As-Built data) again, then go to the next step.

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

No

Go to the next step.

3

• Clear the DTC for the audio amplifier using the M-MDS.

  (See CLEARING DTC [AUDIO AMPLIFIER].)

• Switch the ignition ON (engine off or on) and wait for 30 s or more.

• Perform a CMDTC self-test using the M-MDS.

  (See DTC INSPECTION [AUDIO AMPLIFIER].)

• Are there any modules other than the audio amplifier displaying the same DTC?

Yes

Replace the instrument cluster, then go to the next step.

(See INSTRUMENT CLUSTER REMOVAL/INSTALLATION.)

No

Go to the next step.

4

• Clear the DTC for the audio amplifier using the M-MDS.

  (See CLEARING DTC [AUDIO AMPLIFIER].)

• Switch the ignition ON (engine off or on) and wait for 30 s or more.

• Retrieve the audio amplifier DTCs using the M-MDS.

  (See DTC INSPECTION [AUDIO AMPLIFIER].)

• Is the same DTC displayed?

Yes

Replace the audio amplifier, then go to the next step.

(See AUDIO AMPLIFIER REMOVAL/INSTALLATION.)

No

Go to the next step.

5

• Are any other DTCs displayed?

Yes

Repair or replace the malfunctioning part according to the applicable DTC troubleshooting.

(See DTC TABLE [AUDIO AMPLIFIER].)

No

DTC troubleshooting completed.
