Terminal Inspection
Disconnect the connector and measure the voltage on the wire harness side.
HINT:
Voltage can not be measured with the connector connected to the skid control ECU as the connector is water
resistance.

DIAGNOSIS SYSTEM
1.
CHECK WARNING LIGHT
(a)
Release the parking brake pedal.
(b)
When the ignition switch is turned ON, check that the ABS
warning light, VSC TRAC warning light, VSC OFF (TRAC
OFF) indicator light, BRAKE warning light and SLIP indi-
cator light come on for approx. 3 seconds.
HINT:
When the parking brake is applied or the level of the brake
fluid is low, the BRAKE warning light comes on.
If the indicator check result is not normal, proceed to trou-
bleshooting for the ABS warning light circuit, VSC TRAC
warning light circuit, VSC OFF (TRAC OFF) indicator light
circuit, BRAKE warning light circuit or SLIP indicator light
circuit.
Trouble Area

ABS warning light circuit
VSC TRAC warning light circuit
VSC OFF (TRAC OFF) indicator light circuit
BRAKE warning light circuit
SLIP indicator light circuit
The DTCs are simultaneously stored in the memory. The
DTCs can be read by connecting the SST between TC
and CG terminals of the DLC3 and observing the blinking
of the ABS and VSC warning lights, or by connecting a
hand–held tester.
This system has a sensor signal check function (TEST
MODE) (See page
The DTC can be read by connecting the SST between ter-
minals TS and CG of the DLC3 and observing the blinking
of the ABS and VSC TRAC warning lights, or by connect-
ing a hand–held tester.
