TEST ITEM
Solenoid Valve
NOTE:
The example shown is for the front right wheel. The procedure for the other wheels is the same as given
below.
 When performing an active test of the ABS function, se lect the main item for each test item. In addition,
when performing an active test of the VDC/TCS function, select the item menu for each test item.
 For the ABS solenoid valve, touch “UP” “KEEP” “DOWN”, and for the ABS solenoid valve (ACT), touch “UP”
“ACTUATOR UP” “ACTUATOR KEEP”, and check to make su re that all solenoid valve (in, out) are operating
as given in the table below.

Touch “ON” and “OFF” on the screen. Make sure AB S motor relay operates as shown in table below.
For Fast and Accurate DiagnosisINFOID:0000000001327675
PRECAUTIONS FOR DIAGNOSIS
 Before performing diagnosis, always read precautions. Refer to BRC-13, "How to Proceed with Diagnosis".
 If ABS actuator and electric unit (control unit), steer ing angle sensor, steering system parts or suspension
system parts have been replaced, or if alignment has been adjusted, be sure to adjust neutral position of
steering angle sensor before driving. Refer to BRC-8, "
Adjustment of Steering Angle Sensor Neutral Posi-
tion".
 After diagnosis is finished, be sure to erase memory. Refer to BRC-26, "
Self-Diagnosis".
 When checking continuity and voltage between units, be sure to check for disconnection, looseness, bend,
or collapse of connector terminals. If any malfuncti on is found, repair or replace connector terminals.
 For intermittent symptoms, possible cause is malfunc tion in harness, harness connector, or terminals. Move
harness, harness connector, and terminals to check for poor connections.
 If a circuit tester is used for the check, be ca reful not to forcibly extend any connector terminal.
 To use CONSULT-III to perform self-diagnosis of ABS act uator and electric unit (control unit), active tests, or
work support, first stop work, then connect CONSULT-III and select “ABS”.
 While self-diagnostic results of CONSULT-III shows malf unction, if CONSULT-III active test is performed, an
engine system error may be indicated. In this case, start engine to resume the normal screen.
 VDC/TCS/ABS system electronica lly controls brake operation and engine output. The following symptoms
may be caused by normal operations:

TROUBLE DIAGNOSIS FOR SYSTEM
1. Disconnect ABS actuator and electric unit (contro
l unit) connector. Then reconnect it securely.
2. Perform self-diagnosis again.
Do any self-diagnosis item appear?
YES >> GO TO 3.
NO >> Poor connection. Repair or replace the applicable connector.
3.CHECK ABS MOTOR AND MOTOR RELAY POWER SUPPLY CIRCUIT
1. Turn ignition switch OFF and disconnect ABS actuat or and electric unit (control unit) connector E56.
2. Check voltage between ABS actuator and electric unit (control unit) harness connector and ground.
3. Check continuity between ABS ac tuator and electric unit (control
unit) harness connector and ground.
OK or NG
OK >> Perform self-diagnosis again. If the same result appears, replace ABS actuator and electric unit (control
unit). Refer to BRC-54
.
NG >> Repair harness or connectors.
DTC C1113 G-SENSORINFOID:0000000001327682
CAUTION:
Sudden turns (such as spin turns, acceleration turns), drifting, etc. may cause the G sensor circuit
indicate a malfunction. However, this is not a malf unction, if normal operation can be resumed after
restarting engine.
INSPECTION PROCEDURE
1.CHECK SELF-DIAGNOSTIC RESULTS
Check the self-diagnostic results.
CAUTION:
When on a turntable, such as at a parking structure entrance, or wh en on a moving object with engine
running, VDC OFF indicator lamp might turn on and self-diagnosis using CONSULT-III the yaw rate
sensor system might be displayed, but in this case ther e is no malfunction in yaw rate sensor circuit.
As soon as vehicle leaves turntable or moving object , restart engine to return the system to normal.
Is the above displayed in the self-diagnosis display items?
YES >> GO TO 2.
NO >> INSPECTION END

AIR CONDITIONING CUT CONTROL
Input/Output Signal ChartINFOID:0000000001325899
*1: This signal is sent to the ECM through CAN communication line.
*2: ECM determines the start signal status by the signals of engine speed and battery voltage.
System DescriptionINFOID:0000000001325900
This system improves engine operati
on when the air conditioner is used.
Under the following conditions, the air conditioner is turned OFF.
 When the accelerator pedal is fully depressed.
 When cranking the engine.
 At high engine speeds.
 When the engine coolant temperature becomes excessively high.
 When operating power steering during low engine speed or low vehicle speed.
 When engine speed is excessively low.
 When refrigerant pressure is excessively low or high.
