(c) Read and record any DTCs from the tire pressure
warning light on the combination meter. Refer to the
illustration for examples of a normal system code
and DTCs 13 and 33.
HINT:
• If the tire pressure warning light does not blink to
indicate any DTCs or the normal system code,
inspect the tire pressure warning light circuit or
13 (TC) and 4 (CG) terminal circuits.
• If 2 or more malfunctions are indicated at the
same time, the lowest numbered DTC is
displayed first.
(d) Refer to the Diagnostic Trouble Code Chart for DTC
information (see page TW-22).
(e) After completing the check, turn the ignition switch
OFF and remove SST from the DLC3.
3. CLEAR DTC (USING INTELLIGENT TESTER)
HINT:
After repairing the malfunctions, clear the DTCs.
(a) Connect the intelligent tester (with CAN VIM) to the
DLC3.
(b) Turn the ignition switch ON.
(c) Erase the DTCs following the prompts on the tester
screen.
HINT:
Refer to the intelligent tester operator's manual for
further details.

DATA LIST / ACTIVE TEST
1. READ DATA LIST
HINT:
Using the intelligent tester's DATA LIST allows switch,
actuator and other item values to be read without
removing any parts. Reading the Data List early in
troubleshooting is one way to save time.
(a) Connect the intelligent tester (with CAN VIM) to the
DLC3.
(b) Turn the ignition switch ON.
(c) Read the DATA LIST according to the display on the
tester.

BRAKE CONTROL – VEHICLE STABILITY CONTROL SYSTEMBC–19

4. FAIL SAFE FUNCTION
(a) When a failure occurs in the ABS with BA, TRC and
VSC systems, the ABS and VSC warning lights
illuminate, the slip indicator light comes on*1 or
remains off*2, and the operations of those systems
are prohibited. In addition to this, when a failure
which disables the EBD operation occurs, the brake
warning light comes on and its operation is
prohibited.
HINT:
*1: for 2WD
*2: for 4WD
(b) If control is prohibited due to a malfunction during
operation, control is disabled gradually to avoid
sudden vehicle instability.
5. INITIAL CHECK
(a) When the vehicle speed first reaches approximately
6 km/h (4 mph) or more after the ignition switch is
turned ON, each solenoid valve and the motor of the
ABS and TRACTION actuator are sequentially
activated to perform electrical checks. During the
initial check, the operating sound of the solenoid
valve and motor can be heard from the engine
compartment, but this does not indicate a
malfunction.
6. SERVICE MODE
(a) VSC operation can be disabled by operating the
intelligent tester.
HINT:
Refer to the intelligent tester operator's manual for
further details.
7. FUNCTION OF COMPONENTS
Components Functions

holding solenoid valve, pressure reduction solenoid
valve, pump motor, and reservoir, and adjusts the brake
fluid pressure applied to each wheel cylinder
• Houses the skid control ECU
Solenoid Relay • Supplies power to each solenoid
• Housed in the skid control ECU
Motor Relay (VSC MTR Relay) • Supplies power to the pump motor
• Installed in engine room No. 1 relay block

CHECK FOR INTERMITTENT
PROBLEMS
1. CHECK FOR INTERMITTENT PROBLEMS
HINT:
A momentary interruption (open circuit) in the connectors
and/or wire harness between the sensors and ECUs can
be detected by using the ECU DATA LIST function of an
intelligent tester.
(a) Turn the ignition switch OFF and connect the
intelligent tester (with CAN VIM) to the DLC3.
(b) Turn the ignition switch ON.
(c) Follow the prompts on the intelligent tester to
display the DATA LIST and select areas where a
momentary interruption should be monitored.
HINT:
• A momentary interruption (open circuit) cannot
be detected for 3 seconds after the ignition
switch is turned ON (initial check).
• If the status remains on the ERROR display,
check for continuity between the ECU and the
sensors, or between ECUs.
• The ERROR display on the intelligent tester
remains on for 1 second after the harness signal
changes from a momentary interruption (open
circuit) to normal condition.
