(g) Check that the skid control buzzer sounds for 3 seconds.
HINT:
Press and hold the TRC OFF switch until the skid control buzzer sounds.
When it starts sounding, turn off the switch.
When the skid control buzzer starts sounding, turn off the TRC OFF switch.
If the skid control buzzer sounds, the sensor calibration is in normal completion.
If the skid control buzzer does not sound, perform the sensor calibration again.
If the skid control buzzer still will not sound, there is malfunction in the steering angle sensor, so check
the DTC.

Fail safe function:
When a failure occurs in the ABS & BA & TRC & VSC systems, the ABS warning light, the VSC warning light
and the TRC OFF indicator light come on and the ABS & BA & TRC & VSC operations are prohibited. In
addition to this, when the failure that disables the EBD operation occurs, the brake warning light comes on
as well and the EBD operation is prohibited.

INSPECTION PROCEDURE
1 INSPECT DLC3 TERMINAL VOLTAGE(Ts TERMINAL)
(a) Turn the ignition switch ON.
(b) Measure the voltage between terminals Ts and CG of the
DLC3.
OK:
Voltage: 10 to 14 V
OK Go to step 3

2 CHECK HARNESS AND CONNECTOR(DLC3 −BODY GROUND)
(a) Check for an open or short circuit in harness and connector between terminal Ts of the DLC3 and the
skid control ECU (See page 01− 32).
NG REPAIR OR REPLACE HARNESS ORCONNECTOR
OK
3 CHECK AND REPAIR HARNESS AND CONNECTOR(SKID CONTROL ECU −DLC3)
