13 | Any of the following lights stay on: (ABS warning light, BRAKE system warning light, DSC indicator light and/or DSC OFF light)
[TROUBLESHOOTING HINTS] • Brake fluid amount is low • Parking brake does not release • No connection at DSC HU/CM HU/CM connector (when DSC HU/CM connector comes off, ABS warning light and BRAKE system warning light illuminate) • DSC HU/CM detected malfunction (input and output device malfunction) • DSC HU/CM detects low voltage in power supply • DSC HU/CM ground malfunction (when DSC HU/CM ground is not securely connected, ABS warning light and BRAKE system warning light illuminate but diagnostic trouble code does not display)

Diagnostic procedure

STEP | INSPECTION | ACTION
--- | --- | ---
1 | INSPECT BRAKE FLUID AMOUNT AND VERIFY THAT PARKING BRAKE RELEASES • Is brake fluid amount normal? • Is parking brake lever released? | Yes | Go to next step.
No | Add brake fluid or release parking brake lever.
2 | INSPECT FOR DTCS IN DSC HU/CM • Inspect the DTC for the DSC ON-BOARD DIAGNOSTIC SYSTEM. • Have DTCs been recorded in memory? | Yes | Perform inspection using appropriate DTC.
No | Go to next step.
3 | INSPECT TO SEE WHETHER MALFUNCTION IS IN CONTROL MODULE CONNECTOR, TERMINAL OR OTHER • Do ABS warning light and BRAKE system warning light go off after 4 s with ignition switch on? | Yes | Temporary poor connection in control module connector. Inspect DSC HU/CM connector, then go to Step 6. Inspect DSC HU/CM connector terminal, then go to Step 7.
No | Go to next step.
4 | INSPECT BATTERY • Is battery voltage normal? | Yes | Go to next step.
No | Inspect battery and charging system.
5 | INSPECT CHARGING SYSTEM • Is battery voltage normal with electrical load (A/C, headlight, etc.) on and engine idling? | Yes | Go to next step.
No | Inspect charging system (drive belt tension, generator, etc.).
6 | VERIFY THAT DSC HU/CM CONNECTOR IS CONNECTED • Is DSC HU/CM securely connected? | Yes | Go to next step.
No | Connect DSC HU/CM connector securely, then go to next step.
7 | VERIFY THAT DSC HU/CM CONNECTOR TERMINAL OR RELATED CONNECTOR TERMINALS ARE CONNECTED • Are DSC HU/CM connector terminal or instrument cluster connector terminal etc. related connector terminals securely connected? | Yes | Inspect and repair followings: • DSC HU/CM power supply and ground system wiring harness. • Instrument cluster
No | Connect DSC HU/CM connector terminal etc. related connector terminals securely.
