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
Diagnosis Procedure
INFOID:0000000010049123
Regarding Wiring Diagram information, refer to
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
