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.
