DIAGNOSIS SYSTEM [ABS ACTUATOR AND ELECTRIC UNIT (CONTROL 

UNIT)]

ACTIVE TEST

CAUTION:

• Do not perform active test while driving vehicle.

• Make sure to completely bleed air from brake system.

• The active test cannot be performed with the ABS warning lamp, VDC OFF indicator lamp, SLIP indi-

cator lamp or brake warning lamp on.

• ABS warning lamp, VDC OFF indicator lamp, SLIP indicator lamp and brake warning lamp are on

during active test.

NOTE:

• When active test is performed while depressing the pedal, the pedal depression amount will change. This is

normal. (Only solenoid valve and ABS motor.)

• “TEST IS STOPPED” is displayed 10 seconds after operation start.

• After “TEST IS STOPPED” is displayed, to perform test again, touch BACK.

Test Item

SOLENOID VALVE

• When performing an active test of the ABS function, select the “MAIN SIGNALS” for each test item. In addi-

tion, when performing an active test of the VDC/TCS function, select the item menu for each test item.

• For ABS solenoid valve, touch “Up”, “Keep”, and “Down” on the display screen. For ABS solenoid valve

(ACT), touch “Up”, “ACT UP”, “ACT KEEP” and confirm that solenoid valves operate as shown in the table

below.

*: ON for 1 to 2 seconds after the touch, and then OFF

C1101, C1102, C1103, C1104 WHEEL SENSOR

Description

INFOID:0000000009479254

When the sensor rotor rotates, the magnetic field changes. It converts the magnetic field changes to current

signals (rectangular wave) and transmits them to the ABS actuator and electric unit (control unit). 

DTC Logic

INFOID:0000000009479255

DTC DETECTION LOGIC

DTC CONFIRMATION PROCEDURE

1.

CHECK SELF DIAGNOSTIC RESULT

With CONSULT.

1. Start engine and drive vehicle at approximately 21 km/h (13 MPH) or more for approximately 5 minutes.

2. Perform self diagnostic result.
Is DTC C1101, C1102, C1103 or C1104 detected?

YES

>> Proceed to diagnosis procedure. Refer to 

BRC-35, "Diagnosis Procedure"

.

NO

>> Inspection End.

Diagnosis Procedure

INFOID:0000000009479256

Regarding Wiring Diagram information, refer to 

BRC-92, "Wiring Diagram - VDC WITHOUT HILL DESCENT

CONTROL/HILL START ASSIST"

.

CAUTION:

Do not check between wheel sensor terminals.

1.

CONFIRM DTC

 With CONSULT

1. Perform self-diagnostic result of ABS and record all active DTCs.

2. Clear all DTCs.

3. Perform DTC confirmation procedure. Refer to 

BRC-35, "DTC Logic"

.

Does DTC C1101, C1102, C1103 or C1104 reset?

YES

>> GO TO 2.

NO

>> Refer to 

GI-42, "Intermittent Incident"

.
