1 | Any of the following lights do not illuminate when the ignition switch is turned to the ON position: (ABS warning light, BRAKE system warning light, DSC indicator light and/or TCS OFF light).
Possible cause | • Inspect each light in the instrument cluster for malfunction • Poor connection at DSC/RSC HU/CM connector

Diagnostic procedure

STEP | INSPECTION | ACTION
--- | --- | ---
1 | INSPECT FOR DTCS IN DSC/RSC HU/CM • Inspect the DTC for the ON-BOARD DIAGNOSTIC SYSTEM. • Have DTCs been stored in memory? | Yes | Perform the applicable DTC inspection. (SeeON-BOARD DIAGNOSIS [DSC/RSC].)
No | Go to the next step.
2 | INSPECT WHETHER MALFUNCTION IS IN INSTRUMENT CLUSTER SYSTEM OR OTHER SYSTEM • Do other warning and indicator lights illuminate when the ignition switch is turned to the ON position? | Yes | Go to the next step.
No | Inspect or repair the instrument cluster (power supply system, ground system).
3 | VERIFY THAT DSC/RSC HU/CM CONNECTOR IS CONNECTED • Is the DSC/RSC HU/CM securely connected? | Yes | Go to the next step.
No | Connect the DSC/RSC HU/CM connector securely, then go to the next step.
4 | VERIFY THAT DSC/RSC HU/CM CONNECTOR TERMINAL OR RELATED CONNECTOR TERMINALS ARE CONNECTED • Are DSC/RSC HU/CM connector terminal, instrument cluster connector terminal, or related connector terminals securely connected? | Yes | Go to the next step.
No | Securely connect the DSC/RSC HU/CM connector terminal and related connector terminals.
5 | INSPECT INSTRUMENT CLUSTER • Inspect the instrument cluster. (See ON-BOARD DIAGNOSIS [DSC/RSC].) • If the instrument cluster normal | Yes | Replace the DSC/RSC HU/CM. (See DSC/RSC HU/CM REMOVAL/INSTALLATION [L.H.D.].) (See DSC/RSC HU/CM REMOVAL/INSTALLATION [R.H.D.].)
No | Replace the instrument cluster. (See INSTRUMENT CLUSTER REMOVAL/INSTALLATION.)
