DTC

C05262A

Steering Angle Sensor Module Signal Stuck In Range

DESCRIPTION

The No. 2 skid control ECU (brake actuator assembly) receives signals from the steering sensor via CAN communication.

HINT:

When a malfunction occurs in the communication line to the steering 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	MIL	Note
C05262A	Steering Angle Sensor Module Signal Stuck In Range	Normal communication between the No. 2 skid control ECU (brake actuator assembly) and the steering sensor and abnormal steering sensor zero point.	Steering sensor Wire harness and connector	Does not come on	Output ECU: No. 2 skid control ECU (brake actuator assembly)

CAUTION / NOTICE / HINT

NOTICE:

Inspect the fuses for circuits related to this system before performing the following procedure.

PROCEDURE

CLEAR DTC

(a) Clear the DTCs.

Chassis > Brake Booster > Clear 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.

(b) Turn the ignition switch to ON (READY).

(d) Check that no speed sensor and/or yaw rate sensor DTCs are output.

Chassis > Brake Booster > Trouble Codes

Chassis > Brake/EPB > Trouble Codes

Result	Proceed to
DTC C05262A is output.	A
CAN communication system DTCs are output.	B
Speed sensor and/or yaw rate sensor DTCs are output.	C

HINT:

If a speed sensor, or the yaw rate sensor is malfunctioning, DTCs for the steering sensor may be stored even though the steering sensor is normal.
If speed sensor and yaw rate sensor DTCs are output simultaneously, repair these malfunctions and then inspect the steering sensor.

3.	CHECK HARNESS AND CONNECTOR (IG1 TERMINAL)

(a) Turn the ignition switch off.

*a	Front view of wire harness connector (to Steering Sensor)

(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.

(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.

Standard Voltage:

Tester Connection	Condition	Specified Condition
G68-9 (IG1) - Body ground	Ignition switch ON	11 to 14 V

REPAIR OR REPLACE HARNESS OR CONNECTOR

4.	CHECK HARNESS AND CONNECTOR (BAT TERMINAL)

(a) Turn the ignition switch off.

*a	Front view of wire harness connector (to Steering Sensor)

(b) Measure the voltage according to the value(s) in the table below.

Standard Voltage:

Tester Connection	Condition	Specified Condition
G68-4 (BAT) - Body ground	Always	11 to 14 V

REPAIR OR REPLACE HARNESS OR CONNECTOR

5.	CHECK HARNESS AND CONNECTOR (ESS TERMINAL)

(a) Measure the resistance according to the value(s) in the table below.

Standard Resistance:

Tester Connection	Condition	Specified Condition
G68-6 (ESS) - Body ground	1 minute or more after disconnecting the cable from the negative (-) auxiliary battery terminal	Below 1 Ω

REPLACE STEERING SENSOR

REPAIR OR REPLACE HARNESS OR CONNECTOR
