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.
DTC No. | Detection Item | DTC Detection Condition | Trouble Area |
---|---|---|---|
C05262A | Steering Angle Sensor Module Signal Stuck In Range | Normal communication between the skid control ECU and the steering angle sensor and abnormal steering angle sensor zero point. |

C | ![]() | REPAIR CIRCUITS INDICATED BY OUTPUT DTCS |
|
3. | CHECK HARNESS AND CONNECTOR (IG1 TERMINAL) |
(a) Turn the engine 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 J32 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 engine switch on (IG).
(f) Measure the voltage according to the value(s) in the table below.
Standard Voltage:
Tester Connection | Condition | Specified Condition |
---|---|---|
J32-4 (IG1) - Body ground | Engine switch on (IG) | 11 to 14 V |
NG | ![]() | REPAIR OR REPLACE HARNESS OR CONNECTOR |
|
4. | CHECK HARNESS AND CONNECTOR (BAT TERMINAL) |
(a) Turn the engine switch off. |
|
(b) Measure the voltage according to the value(s) in the table below.
Standard Voltage:
Tester Connection | Condition | Specified Condition |
---|---|---|
J32-5 (BAT) - Body ground | Always | 11 to 14 V |
NG | ![]() | REPAIR OR REPLACE HARNESS OR CONNECTOR |
|
5. | CHECK HARNESS AND CONNECTOR (GROUND TERMINAL) |
(a) Measure the resistance according to the value(s) in the table below.
Standard Resistance:
Tester Connection | Condition | Specified Condition |
---|---|---|
J32-1 (ESS) - Body ground | 1 minute or more after disconnecting the cable from the negative (-) battery terminal | Below 1 Ω |
OK | ![]() | REPLACE STEERING ANGLE SENSOR |
NG | ![]() | REPAIR OR REPLACE HARNESS OR CONNECTOR |
