C1105, C1106, C1107, C1108 WHEEL SENSOR

C1105, C1106, C1107, C1108 WHEEL SENSOR

Description

INFOID:0000000010296030

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).

YES

>> Proceed to diagnosis procedure. Refer to

BRC-60, "Diagnosis Procedure"

.

NO

>> Inspection End.

Diagnosis Procedure

INFOID:0000000010296032

Regarding Wiring Diagram information, refer to

BRC-44, "Wiring Diagram"

.

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-60, "DTC Logic"

.

Does DTC C1105, C1106, C1107 or C1108 reset?

YES

>> GO TO 2.

NO

>> Refer to

GI-39, "Intermittent Incident"

.

2.

CHECK TIRE PRESSURE AND TIRE WEAR
