Lexus RX (RX 350L, RX450h) 2016-2025 Repair Manual: Steering Angle Sensor Module Signal Stuck In Range (C05262A)
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. |

CAUTION / NOTICE / HINT
NOTICE:
Inspect the fuses for circuits related to this system before performing the following procedure.
PROCEDURE
| 1. | CLEAR DTC |
(a) Connect the Techstream to the DLC3.
(b) Turn the engine switch on (IG).
(c) Operate the Techstream to clear the codes. Enter the following menus: Chassis / Brake/EPB / Trouble Codes.
Chassis > Brake/EPB > Clear DTCs(d) Press the DTC clear button.
(e) Turn the engine switch off.

(b) Start the engine.
(c) Drive the vehicle at a speed of 35 km/h (22 mph) and turn the steering wheel to the right and left.
(d) Read the DTCs following the prompts on the Techstream. Enter the following menus: Chassis / Brake/EPB / Trouble Codes.
Chassis > Brake/EPB > Trouble Codes(e) Check that no speed sensor or yaw rate sensor (yaw rate and acceleration sensor) 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 (yaw rate and acceleration sensor) DTCs are output. | C |
HINT:
- If a speed sensor, or the yaw rate sensor (yaw rate and acceleration sensor) is malfunctioning, DTCs for the steering angle sensor may be stored even though the steering angle sensor is normal.
- If speed sensor and yaw rate sensor (yaw rate and acceleration sensor) DTCs are output simultaneously, repair these malfunctions and then inspect the steering angle sensor.

| 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 |
