BHE040343000W13

2 | Any of the following lights remain 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 connector (When DSC HU/CM connector is disconnected, 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 displayed) • DSC HU/CM does not operate (DSC HU/CM malfunction)

Diagnostic procedure

STEP | INSPECTION | ACTION
--- | --- | ---
1 | INSPECT BRAKE FLUID AMOUNT AND VERIFY THAT PARKING BRAKE RELEASES • Is the brake fluid amount normal? • Is the parking brake lever released? | Yes | Go to the next step.
No | Add brake fluid or release parking brake lever.
2 | INSPECT DTCS IN DSC HU/CM • Inspect the DTC for the DSC ON-BOARD DIAGNOSTIC SYSTEM. • Have DTCs been stored in memory? | Yes | Perform inspection using appropriate DTC. (See DTC Table.)
No | Go to the next step.
3 | INSPECT WHETHER MALFUNCTION IS IN CONTROL MODULE CONNECTOR, TERMINAL OR OTHER • Do ABS warning light and BRAKE system warning light go off after 4 s when the ignition switch is turned to the ON position? | 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 the next step.
4 | INSPECT BATTERY • Is the battery voltage normal? | Yes | Go to the next step.
No | Inspect the battery and charging system. (See BATTERY INSPECTION.) (See GENERATOR INSPECTION.)
5 | INSPECT CHARGING SYSTEM • Is the battery voltage normal with electrical load (A/C, headlight, etc.) on and engine idling? | Yes | Go to the next step.
No | Inspect the charging system (drive belt tension, generator, etc.). (See GENERATOR INSPECTION.)
6 | VERIFY THAT DSC HU/CM CONNECTOR IS CONNECTED • Is the DSC HU/CM securely connected? | Yes | Go to the next step.
No | Connect the DSC HU/CM connector securely, then Go to the 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 | Replace the DSC HU/CM. (See DSC HU/CM REMOVAL/INSTALLATION.)
No | Securely connect the DSC HU/CM connector terminal and related connector terminals.
