C1156 ST ANG SEN COM CIR

Description

INFOID:0000000010049115

The steering angle sensor is connected to the ABS actuator and electric unit (control unit) in addition to CAN

lines. CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle

multiplex communication line with high data communication speed and excellent error detection ability. Many

electronic control units are equipped onto a vehicle, and each control unit shares information and links with

other control units during operation (not independent). In CAN communication, control units are connected

with 2 communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less

wiring. Each control unit transmits/receives data but selectively reads required data only.

PARKING BRAKE SWITCH

PARKING BRAKE SWITCH

Description

INFOID:0000000010049121

The parking brake switch converts the status of the parking brake pedal to an electric signal and transmits it to

the combination meter. The combination meter, through CAN communication, transmits the signal to the ABS

actuator and electric unit (control unit).

Component Function Check

INFOID:0000000010049122

1.

CHECK PARKING BRAKE SWITCH OPERATION

Operate the parking brake and check that the brake warning lamp in the combination meter turns on/off cor-

rectly.

Is the inspection result normal?

YES

>> Inspection End.

NO

>> Go to diagnosis procedure. Refer to 

BRC-68, "Diagnosis Procedure"

.

Diagnosis Procedure

INFOID:0000000010049123

Regarding Wiring Diagram information, refer to 

BRC-83, "Wiring Diagram"

.

1.

CHECK PARKING BRAKE SWITCH CIRCUIT

1. Disconnect combination meter connector and parking brake

switch connector. 

2. Check continuity between combination meter connector M24 (A)

terminal 26 and parking brake switch connector E35 (B) terminal

1.

3. Check continuity between combination meter harness connector

M24 (A) terminal 26 and ground.

Is the inspection result normal?

YES

>> GO TO 2

NO

>> Repair harness or connector.

2.

CHECK PARKING BRAKE SWITCH

Perform parking brake switch component inspection. Refer to 

BRC-69, "Component Inspection"

.

Is the inspection result normal?

YES

>> Check parking brake switch case ground condition.

NO

>> Replace parking brake switch.
