Diagnostic Procedure

Step

Inspection

Action
1
VERIFY INSTRUMENT CLUSTER DTCs
•  Retrieve the instrument cluster DTCs using the M-MDS.
•  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
VERIFY ALL SYSTEM DTCs
•  Clear the DTC for the audio amplifier using the M-MDS.
•  Switch the ignition ON (engine off or on) and wait for 30 s or more.
•  Perform a CMDTC self-test using the M-MDS.
•  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
VERIFY ALL SYSTEM DTCs AGAIN
•  Clear the DTC for the audio amplifier using the M-MDS.
•  Switch the ignition ON (engine off or on) and wait for 30 s or more.
•  Perform a CMDTC self-test using the M-MDS.
•  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
RESET CONFIGURATION DATA FROM INSTRUMENT CLUSTER TO AUDIO AMPLIFIER
•  Clear the DTC for the audio amplifier using the M-MDS.
•  Switch the ignition ON (engine off or on) and wait for 30 s or more.
•  Retrieve the audio amplifier DTCs using the M-MDS.
•  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
VERIFY IF OTHER DTCs DISPLAYED
