DTC |
C05262A |
Steering Angle Sensor Module Signal Stuck In Range |
DESCRIPTION
The skid control ECU (brake actuator assembly) receives signals from the steering angle sensor via CAN communication.
HINT:
When a malfunction occurs in the communication line to the steering angle sensor, U012687 is output.
If a DTC related to the CAN communication line is output, first troubleshoot the CAN communication line.

CAUTION / NOTICE / HINT
NOTICE:
Inspect the fuses for circuits related to this system before performing the following procedure.
PROCEDURE
|
1. |
CLEAR DTC |
(a) Clear the DTCs.
Chassis > Brake/EPB > Clear DTCs
(b) Turn the ignition switch off.
|
|
2. |
RECONFIRM DTC |
(a) Turn the ignition switch to ON and check that no CAN communication system DTCs are output.

Result |
Proceed to |
|---|---|
|
DTC C05262A is output. |
A |
|
CAN communication system DTCs are output. |
B |
|
Speed sensor and/or yaw rate sensor (airbag sensor assembly) DTCs are output. |
C |
HINT:
- If a speed sensor, or the yaw rate sensor (airbag sensor assembly) is malfunctioning, DTCs for the steering angle sensor may be stored even though the steering angle sensor is normal.
- If speed sensor and/or yaw rate sensor (airbag sensor assembly) DTCs are output simultaneously, repair these malfunctions and then inspect the steering angle sensor.

CHECK HARNESS AND CONNECTOR (IGR TERMINAL) |
|
(a) Turn the ignition switch off. |
|
(b) Make sure that there is no looseness at the locking part and the connecting part of the connectors.
OK:
The connector is securely connected.
(c) Disconnect the I46 steering angle sensor connector.
(d) Check both the connector case and the terminals for deformation and corrosion.
OK:
No deformation or corrosion.
(e) Turn the ignition switch to ON.
(f) Measure the voltage according to the value(s) in the table below.
