Toyota Corolla Cross: Steering Angle Sensor Wrong Installation (X0455)

DESCRIPTION

Code	Tester Display	Measurement Item	Trouble Area	Output ECU
X0455	Steering Angle Sensor Wrong Installation	History of steering sensor being installed incorrectly	Correct spiral cable with sensor sub-assembly Steering sensor	Skid control ECU (brake actuator assembly)

CAUTION / NOTICE / HINT

NOTICE:

After performing the inspection, check and clear the vehicle control history (RoB).

HINT:

When Steering Angle Sensor Wrong Installation (X0455) is stored, output control may operate, but this is not a malfunction.

PROCEDURE

1.	CHECK DTC (HEALTH CHECK)

(a) Perform the Health Check using the GTS.

Result	Proceed to
DTCs are not output	A
DTCs are output	B

GO TO DIAGNOSTIC TROUBLE CODE CHART

A

2.	ALIGN FRONT WHEELS FACING STRAIGHT AHEAD

3.	READ VALUE USING GTS (STEERING ANGLE SIGNAL INFORMATION)

(a) Check Data List item "Steering Angle Signal Information".

Chassis > Steering Angle Sensor > Data List

Tester Display	Measurement Item	Range	Normal Condition	Diagnostic Note
Steering Angle Signal Information	Steering angle value (Rotation to the left side is positive)	Min.: -3072.0 deg Max.: 3070.5 deg	Turning left: 0.0 to 3070.5 deg Turning right: -3072.0 to 0.0 deg	During steering operation: Changes in proportion with steering wheel rotation

Steering Angle Signal Information

(b) Save the steering angle signal information to the GTS memory.

NOTICE:

• If the value is +/- 360 deg (+/-15 deg), the steering sensor was incorrectly installed by 1 rotation.
• If the value is +/- 720 deg (+/-15 deg), the steering sensor was incorrectly installed by 2 rotations.
• In situations other than the above, the steering sensor may have been incorrectly installed by 3 or more rotations.

  In this case, it is possible that the proper installation or removal procedures were not followed, and the steering sensor may have been damaged.

Result	Proceed to
0 deg (+/- 15 deg)	A
+/- 360 deg (+/-15 deg) or +/- 720 deg (+/-15 deg)	B
None of the above conditions are met	C

4.	CLEAR VEHICLE CONTROL HISTORY (RoB)

(a) Using the GTS, clear the Vehicle Control History (RoB).

Chassis > Brake/EPB > Utility

Vehicle Control History (RoB)

NEXT

5.	PERFORM ZERO POINT CALIBRATION OF STEERING SENSOR

(a) Disconnect cable from negative (-) auxiliary battery terminal.

HINT:

If the cable is not disconnected from the negative (-) auxiliary battery terminal, it may not be possible to obtain an accurate steering sensor zero point.

(b) Connect cable to negative (-) auxiliary battery terminal.

(c) Drive the vehicle straight ahead at 35 km/h (22 mph) or more for at least 5 seconds.

NEXT

6.	CHECK VEHICLE CONTROL HISTORY (RoB)

(a) Based on the Freeze Frame Data and interview with the customer, attempt to reproduce the conditions when the malfunction occurred.

(b) Using the GTS, check for Vehicle Control History (RoB).

7.	ADJUST SPIRAL CABLE WITH SENSOR SUB-ASSEMBLY

(a) Remove the spiral cable with sensor sub-assembly.

NOTICE:

• Be sure to disconnect the cable from the negative (-) auxiliary battery terminal before removing the spiral cable with sensor sub-assembly.

  HINT:

  If the cable is not disconnected from the negative (-) auxiliary battery terminal, it may not be possible to obtain an accurate steering sensor zero point.

• Do not disconnect the steering sensor from the spiral cable.

(b) Based on the internal steering angle value that was saved to the GTS memory earlier, rotate the spiral cable with sensor sub-assembly.

*A w/o Heated Steering Wheel System *B w/ Heated Steering Wheel System *C Clockwise *D Counterclockwise *a Interlock

NOTICE:

• Rotate the steering sensor without disconnecting it from the spiral cable.
• Make sure to follow the adjustment method shown in the table.
• Failure to observe the following precautions may result in damage to the spiral cable with sensor sub-assembly.
  • When rotating the spiral cable with sensor sub-assembly, make sure to push on the interlock to release the interlock.
  • Do not turn the spiral cable with sensor sub-assembly using the airbag wire harness.
  • Do not forcibly rotate the part.
  • Make sure to perform the correct number of rotations in the correct direction.

Steering Angle Signal Information	Correction Method
360 deg (+/-15 deg)	Rotate clockwise (to the right), 1 rotation.
- 360 deg (+/-15 deg)	Rotate counterclockwise (to the left), 1 rotation.
720 deg (+/-15 deg)	Rotate clockwise (to the right), 2 rotations.
- 720 deg (+/-15 deg)	Rotate counterclockwise (to the left), 2 rotations.

(c) Install the spiral cable with sensor sub-assembly.
