1

Any of the following lights do not illuminate with ignition switch on: (ABS warning light, BRAKE system warning light, DSC indicator light and/or TCS OFF light).

[TROUBLESHOOTING HINTS]

• Check each light in the instrument cluster for malfunction

• Poor connection at DSC unit connector

• ABS warning light circuit or BRAKE system warning light circuit shorted out

(when harness is shorted out between DSC unit and ABS warning light or BRAKE system warning light, each warning lights go off)

• DSC indicator light circuit and/or TCS OFF light circuit may be open

(when DSC indicator light circuit and/or TCS OFF light circuit is open, each circuit's warning lights go off)

Diagnostic procedure

STEP

INSPECTION

ACTION

1
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.
2
CHECK TO SEE WHETHER MALFUNCTION IS IN INSTRUMENT CLUSTER SYSTEM OR OTHER SYSTEM
• Do other warning and indicator lights illuminate when IG switch is turned ON?
Yes
Go to next step.
No
Inspect or repair instrument cluster (power supply system, ground system).
3
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.
4
VERIFY THAT DSC UNIT CONNECTOR TERMINAL OR RELATED CONNECTOR TERMINALS ARE CONNECTED
• Are DSC unit connector terminal, or instrument cluster connector terminal, or related connector terminals securely connected?
Yes
Go to next step.
No
Connect DSC unit connector terminal etc. related connector terminal securely.
5
CHECK TO SEE WHETHER MALUNCTION IS IN DSC INDICATOR LIGHT AND TCS OFF LIGHT OR ABS WARNING LIGHT AND BRAKE SYSTEM WARNING LIGHT
• If DSC indicator light and TCS OFF light do not illuminate, go to Step 6.
• If ABS warning light and BRAKE system warning light do not illuminate, go to Step 8.

6
CHECK TO SEE WHETHER MALFUNCTION IS IN DSC UNIT OR OTHER
• Disconnect DSC unit.
• Connect the DSC indicator light terminal and TCS OFF light terminal to body ground.
• Do both indicator lights illuminate with ignition switch on?
Yes
Replace DSC unit (open in DSC unit).
No
Go to next step.
7
INSPECT WIRING HARNESS BETWEEN INSTRUMENT CLUSTER AND DSC UNIT FOR CONTINUITY
• Is there continuity between each indicator light terminals of instrument cluster and DSC unit connector terminal?
Yes
Inspect or repair indicator light circuit in instrument cluster.
No
Repair malfunctioning part.
8
CHECK TO SEE WHETHER MALFUNCTION IS IN DSC UNIT OR OTHER
• Disconnect DSC unit and turn ignition switch on.
• Do ABS warning light and BRAKE system warning lights illuminate with ignition switch on?
(If above lights illuminate, both lights circuits are normal.)
Yes
Replace DSC unit (short in DSC unit).
No
Go to next step.
9
INSPECT WIRING HARNESS BETWEEN INSTRUMENT CLUSTER AND DSC UNIT FOR SHORT
• Is there continuity between each warning light terminal of DSC unit and ground?
Yes
Repair malfunctioning part.
No
Inspect or repair warning light circuit in instrument cluster.
