ABS Warning Light Circuit
CIRCUIT DESCRIPTION
If the ECU detects any trouble, it lights the ABS warning light while at the same time prohibiting ABS control.
At this time, the ECU records a DTC in memory.
Connect terminals Tc and E
1 of the DLC1 or DLC2 to make the ABS warning light blink and output the DTC.
WIRING DIAGRAM
INSPECTION PROCEDURE
Troubleshoot in accordance with the chart below for each trouble symptom
ABS warning light does not light upGo to step 1
ABS warning light remains onGo to step 2
1 Check ABS warning light.
See combination meter troubleshooting on page BE±2.
NG Repair bulb or combination meter assembly.
OK
Check for open circuit in harness and connector between GAUGE fuse, DLC2 and ABS ECU
(See page IN±31).

SRS Warning Light Circuit Malfunction (Does not light up, when
ignition switch is turned to ACC or ON.)
CIRCUIT DESCRIPTION
The SRS warning light is located on the combination meter.
When the SRS is normal, the SRS warning light lights up for approx. 6 seconds after the ignition switch is
turned from LOCK position to ACC or ON position, and then turns off automatically.
If there is a malfunction in the SRS, the SRS warning light lights up to inform the driver of the abnormality.
When terminals Tc and E1 of the DLC1 are connected, the DTC is displayed by blinking the SRS warning
light.
WIRING DIAGRAM
