BRC-218 < COMPONENT DIAGNOSIS > [TYPE 3] C1101, C1102, C1103, C1104 WHEEL SENSOR-1 C1101, C1102, C1103, C1104 WHEEL SENSOR-1 Description INFOID:0000000005275253 When the sensor rotor rotates, the magnetic field changes. It converts the magnetic field changes to current DTC Logic INFOID:0000000005275254 DTC DETECTION LOGIC DTC CONFIRMATION PROCEDURE 1. CHECK SELF-DIAGNOSIS RESULTS Check the self-diagnosis results. Is above displayed on the self-diagnosis display? YES >> Proceed to diagnosis procedure. Refer to BRC-218, "Diagnosis Procedure" . NO >> Inspection End Diagnosis Procedure INFOID:0000000005275255 Regarding Wiring Diagram information, refer to BRC-275, "Wiring Diagram - BRAKE CONTROL SYSTEM - WITH HILL DESCENT CONTROL/HILL START ASSIST" . CAUTION: Do not check between wheel sensor terminals. 1. CONNECTOR INSPECTION 1. Disconnect the ABS actuator and electric unit (control unit) connector and wheel sensor of malfunctioning 2. Check the terminals for deformation, disconnection, looseness or damage. Is the inspection result normal? YES >> GO TO 2 NO >> Repair or replace as necessary. 2. CHECK WHEEL SENSOR OUTPUT SIGNAL 1. Connect ABS active wheel sensor tester (J-45741) to wheel sensor using appropriate adapter. 2. Turn on the ABS active wheel sensor tester power switch.
