NO.9 ANY OF THE FOLLOWING LIGHTS REMAIN ON: (ABS WARNING LIGHT, BRAKE SYSTEM WARNING LIGHT, DSC INDICATOR LIGHT AND/OR DSC OFF LIGHT)

B3E040367650W13

9 | 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 is not released.

• No connection at DSC HU/CM connector

(When DSC HU/CM connector goes out, 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 circuit.

• DSC HU/CM ground malfunction

(When DSC HU/CM ground is not securely connected, ABS warning light and BRAKE system warning light illuminate but no DTC is 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 the parking brake lever.
2 | INSPECT FOR DTCs IN DSC HU/CM • Have DTCs been stored in memory? | Yes | Perform the applicable DTC inspection. (See DTC Table.)
No | Go to the next step.
3 | INSPECT IF MALFUNCTION IS IN CONTROL MODULE CONNECTOR, TERMINAL OR OTHER • Do ABS warning light and BRAKE system warning light go out after 4 s with the ignition switch turned to the ON position? | Yes | Temporary poor connection in control module connector. Inspect the DSC HU/CM connector, then go to Step 6. Inspect the 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 [ZJ, Z6].) (See GENERATOR INSPECTION [LF].)
5 | INSPECT CHARGING SYSTEM • Is the battery voltage normal with electrical load (such as A/C, headlight) on and engine idling? | Yes | Go to the next step.
No | Inspect the charging system (such as drive belt tension, generator). (See GENERATOR INSPECTION [ZJ, Z6].) (See GENERATOR INSPECTION [LF].)
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, related connector terminals securely connected? | Yes | Replace the DSC HU/CM. (See DSC HU/CM REMOVAL/INSTALLATION.)
No | Connect the DSC HU/CM connector terminal or related connector terminals securely.
