NO.1 NEITHER ABS WARNING LIGHT NOR BRAKE SYSTEM WARNING LIGHT ILLUMINATE WITH IGNITION SWITCH ON


1	Neither ABS warning light nor BRAKE system warning light illuminate with ignition switch on.
[TROUBLESHOOTING HINTS] • Instrument cluster or ABS HU/CM malfunction • Improper configuration


STEP	INSPECTION		ACTION
1	CONFIRM THE FOLLOWING PIDs USING WDS OR EQUIVALENT: • ABS_MSG • PCM_MSG • Is "not present" massage displayed on WDS or equivalent?	Yes	Replace ABS CM.
1		No	Inspect instrument cluster. If instrument cluster is normal, inspect CAN communication. If instrument cluster malfunction, then go to next step.
2	VERIFY WHETHER MALFUNCTION IS IN WARNING LIGHTS AND INDICATOR LIGHT'S COMMON POWER SUPPLY, OR IN OTHER WARNING LIGHTS AND INDICATOR LIGHTS • Do other warning and indicator lights illuminate when IG switch is turned ON?	Yes	Replace instrument cluster (open circuit in instrument cluster).
2		No	Go to next step.
3	INSPECT INSTRUMENT CLUSTER POWER SUPPLY FUSE • Is instrument cluster ignition power supply fuse normal?	Yes	Go to next step.
3		No	Inspect for a short to ground on circuit of blown fuse. Repair or replace as necessary. Install appropriate amperage fuse.
4	VERIFY WHETHER MALFUNCTION IS IN WIRING HARNESS (BETWEEN INSTRUMENT CLUSTER POWER SUPPLY AND INSTRUMENT CLUSTER FOR CONTINUITY) OR INSTRUMENT CLUSTER • Turn ignition switch ON. • Measure voltage at instrument cluster connector (24-pin) terminal 2V. • Is voltage approx. 12V?	Yes	Replace instrument cluster (open circuit in instrument cluster).
4		No	Inspect for open circuit between instrument cluster and ground. Repair or replace as necessary.

• When performing an asterisked (*) troubleshooting inspection, shake the wiring harness and connectors while doing the inspection to discover whether poor contact points are the cause of any intermittent malfunction. If there is a problem, inspect to make sure connectors, terminals and wiring harnesses are connected correctly and undamaged.
