Any of the following lights stay on: (ABS warning light, BRAKE system warning light, DSC indicator light and/or TCS OFF light)

[TROUBLESHOOTING HINTS]

• Brake fluid amount is low

• Parking brake does not release

• No connection at DSC unit connector

(when DSC unit connector comes off, ABS warning light and BRAKE system warning light illuminate)

• DSC unit detected malfunction (input and output device malfunction)

• DSC unit detects low voltage in power supply

• DSC unit ground malfunction

(when DSC unit ground is not securely connected, ABS warning light and BRAKE system warning light illuminate but diagnostic trouble code does not display)

• DSC unit does not operate (DSC unit malfunction)

• TCS OFF light circuit shorted in ground (when TCS OFF circuit is shorted in ground, TCS OFF light illuminated)

• ABS warning light circuit or BRAKE system warning light circuit open

(when the harness is open between DSC unit and each warning light, each warning light illuminates)

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
CHECK FOR DTCS IN DSC UNIT
• Check 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
CHECK 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 seconds with ignition switch on?
Yes
Temporary poor connection in control module connector.
Inspect DSC unit connector, then go to Step 6.
Inspect DSC unit 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 UNIT CONNECTOR IS CONNECTED
• Is DSC unit securely connected?
Yes
Go to next step.
No
Connect DSC unit connector securely, then go to next step.
7
VERIFY THAT DSC UNIT CONNECTOR TERMINAL OR RELATED CONNECTOR TERMINALS ARE CONNECTED
• Are DSC unit connector terminal or instrument cluster connector terminal etc. related connector terminals securely connected?
Yes
Go to next step.
No
Connect DSC unit connector terminal etc. related connector terminals securely.
8
INSPECT WIRING HARNESS BETWEEN INSTRUMENT CLUSTER AND DSC UNIT FOR CONTINUITY
• Is there continuity between each warning light terminal of instrument cluster and DSC unit connector terminal?
Yes
Go to next step.
No
Repair malfunctioning part.
9
INSPECT WIRING HARNESS BETWEEN INSTRUMENT CLUSTER AND DSC UNIT FOR SHORT IN GROUND
• Is there continuity between each indicator light terminal of DSC unit and ground?
Yes
Repair malfunctioning part.
No
Inspect power supply harness and ground harness of DSC unit.
If above wiring harness are okay, replace DSC unit.
If above wiring harness are malfunction, repair malfunctioning wiring harness.
