DTC |
C1434 |
Steering Angle Sensor Output |
DESCRIPTION
Steering angle sensor signals are input to the skid control ECU (brake booster with master cylinder assembly) via the CAN communication system.
HINT:
When a malfunction occurs in the communication line to the steering angle sensor, U0126 (Lost Communication With Steering Angle Sensor Module) is output.
If a DTC related to the CAN communication line is output, first troubleshoot the CAN communication line.
DTCs may be stored if one of the following occurs:
- Steering angle sensor zero point malfunction.
- Steering angle sensor signal malfunction.
- Steering angle sensor installation abnormality.

CAUTION / NOTICE / HINT
NOTICE:
Inspect the fuses for circuits related to this system before performing the following procedure.
PROCEDURE
|
1. |
CHECK DTC |
(a) Clear the DTCs.
Chassis > ABS/VSC/TRAC > Clear DTCs
(b) Turn the power switch off.
(c) Turn the power switch on (IG) again and check that no CAN communication system DTCs are output.

(d) Turn the power switch on (READY).
(e) Drive the vehicle at a speed of 35 km/h (22 mph), turn the steering wheel to the right and left, and check that no speed sensor and/or yaw rate and acceleration sensor DTCs are output.

Result |
Proceed to |
|---|---|
|
DTC C1434 is output. |
A |
|
CAN communication system DTCs are output. |
B |
|
Speed sensor and/or yaw rate and acceleration sensor DTCs are output. |
C |
HINT:
- If there is a malfunction in a speed sensor or the yaw rate and acceleration sensor (airbag sensor assembly), an abnormal value may be output even though the steering angle sensor is normal.
- If speed sensor and yaw rate and acceleration sensor DTCs are output simultaneously, repair these malfunctions and inspect the steering angle sensor.

3. |
CHECK HARNESS AND CONNECTOR (POWER SOURCE TERMINAL) |
|
(a) Remove the steering wheel and column cover. |
|
(b) Make sure that there is no looseness at the locking part and the connecting part of the connector.
OK:
The connector is securely connected.
(c) Disconnect the K71 steering angle sensor connector.
(d) Check both the connector case and the terminals for deformation and corrosion.
OK:
No deformation or corrosion.
(e) Measure the voltage according to the value(s) in the table below.

CHECK HARNESS AND CONNECTOR (GND TERMINAL) |
|
(a) Turn the power switch off. |
|
(b) Measure the resistance according to the value(s) in the table below.
NOTICE:
Before measuring the resistance of the steering angle sensor, turn the power switch off and leave the vehicle for 1 minute or more without operating the key or switches, or opening or closing the doors.
