Steering Angle Sensor: Adjustments
SUB STEERING ANGLE SENSOR ADJUSTMENTFront sub steering angle sensor
NOTE: Before adjusting the sub steering angle sensor, check that the front main steering angle sensor is adjusted properly.
1. Jack up the car and raise all four wheels off the ground. Place the safety stands in the proper locations to support the car.
2. Set the steering wheel in the straight driving position.
3. Take out the service check connector (BLU 2P) from behind the center console. Connect the terminals with a piece of jumper wire.
NOTE:
^ The 4WS indicator light will not indicate that the sensors are in the electronic neutral position when displaying stored problem codes.
^ Check and verify any problem codes displayed before checking the electronic neutral position.
4. Set the parking brake lever and turn the ignition switch on (engine off). Be sure that the parking brake indicator light turns on.
5. Turn the ignition switch off.
6. Cut the wire tie from the sub steering angle sensor cover, then remove the cover from the sub steering angle sensor.
CAUTION: Use care when cutting the wire tie so as not to cut into the wire harness.
7. Remove the sub steering angle sensor wire harness from the clamp and disconnect the connector.
8. Loosen the locknut. Tighten the locknut fully by hand, back it off about 3/4 turns and connect the connector.
9. Turn the ignition switch on (engine off
10. Set the steering wheel in the straight driving position. Set the front main steering angle sensor electronically in neutral (4WS indicator light is blinking) this time.
NOTE: Hold the steering wheel in this position until adjustment is completed. If the steering wheel is moved in error, repeat the adjustment procedure starting with step 10.
11. Turn the front sub steering angle sensor slowly clockwise, and check the range from where the light starts to blink to where it stops.
12. Loosen the front sub steering angle sensor. Repeat the step 11 several times to set the sub steering angle sensor in the center of the range from where the light starts to blink to where it stops.
NOTE:
^ Turn the front sub steering angle sensor clockwise to make the 4WS indicator light blink.
^ If the sub steering angle sensor wire is twisted excessively, turn the ignition switch off, disconnect the connector, and straighten the wire.
13. Tighten the locknut while holding the front sub steering angle sensor with a wrench.
NOTE: Take care not to turn the front sub steering angle sensor.
14. Disconnect the front sub steering angle sensor connector to straighten the wire.
Reconnect the connector.
NOTE: Do not contaminate the front sub steering angle sensor connector terminals with mud, oil, and grease.
15. Check that each sensor is electronically in neutral (see page 17-146).
NOTE: Be sure that the center of the range where the 4WS indicator light blinks (indicating that the front sub steering angle sensor is electronically in neutral), is in the range ±18 mm (±O.7 in; ±5.5°) from the center mark on the steering wheel.
16. Reconnect the connector and secure the sub steering angle sensor wire harness with the clamp and install the cover.
NOTE:
^ Be sure the sensor wire harness does not interfere with the stabilizer or other moving parts.
^ Be certain that the wire is not twisted before connecting it.
17. Secure the cover with a new wire tie.
Rear sub steering angle sensor
1. Jack up the car and raise all four wheels off the ground. Place the safety stands in the proper locations to support the car.
2. Take out the service check connector (BLU 2P) from behind the center console. Connect the terminals with a piece of jumper wire.
NOTE:
^ The 4WS indicator light will not indicate that the sensor are in electrically neutral position, when displaying stored problem codes.
^ Check and verify any problem codes displayed before checking the electrically neutral position.
3. Release the parking brake lever fully and turn the ignition switch on (engine off). Be sure that the parking brake indicator light goes off.
4. Turn the ignition switch off.
Sub Steering Angle Sensor Adjustment
5. Remove the rear actuator cover.
6. Remove the cap bolt and sealing washer from the rear actuator. Screw the special tool in as far as it will go.
7. Remove the rear sub steering angle sensor wire from the clamp and disconnect the connector.
8. Loosen the angle sensor locknut. Tighten the locknut fully by hand, then back it off about 1/2 turn and connect the connector.
9. Set the steering wheel in the straight driving position to prevent the rear wheels from steering if the engine is started in error.
10. Turn the ignition switch on (engine off).
11. Turn the rear left wheel fully to the left by hand, then turn it slowly to the right to turn the 4W5 indicator light on (i.e. rear main steering angle sensor is electronically in neutral).
NOTE:
^ The 4W5 indicator light turns on in a narrow range. Do not overlook it.
^ Work with care so as not to move the rear wheels from this neutral position.
12. Turn the ignition switch on (engine off).
13. Turn the rear sub steering angle sensor slowly counterclockwise, and check the range from where the light starts to blink, to where it stops.
14. Tighten the rear sub steering angle sensor a little. Repeat the step 13 several times to set the sub steering angle sensor in the center of the range from where the light starts to blink, to where it stops.
NOTE:
^ Turn the rear sub steering angle sensor counterclockwise to make the 4WS indicator light blink.
^ If the rear sub steering angle sensor wire is twisted excessively, turn the ignition switch off, disconnect the connector, and straighten the wire.
15. Tighten the locknut while holding the rear sub steering angle sensor with a wrench.
NOTE: Take care not to turn the rear sub steering angle sensor.
16. Disconnect the rear sub steering angle sensor connector to straighten the wire. Reconnect the connector.
NOTE: Do not contaminate the rear sub steering angle sensor connector terminals with mud, oil, and grease.
17. Check that each sensor is electronic in neutral.
18. Turn the ignition switch off. Remove the special tool from the rear actuator, and install the cap bolt and the new sealing washer on the rear actuator.
19. Install the rear actuator cover.
