Adjustment of Steering Angle Sensor Neutral Position

EFS0067L

After removing/installing or replacing ABS actuator and electric unit (control unit), steering angle sensor, steer-
ing and suspension components which affect wheel alignment or after adjusting wheel alignment, be sure to
adjust neutral position of steering angle sensor before running vehicle.

WITH CONSULT-II

1.

Stop vehicle with front wheels in straight-ahead position.

2.

Connect CONSULT-II and CONSULT-II CONVERTER to data
link connector on vehicle, and turn ignition switch ON (do not
start engine).

3.

Touch “START (NISSAN BASED VHCL)”, “ABS”, “WORK SUP-
PORT” and “ST ANGLE SENSOR ADJUSTMENT” on CON-
SULT-II screen in this order.

4.

Touch “START”.

CAUTION:

Do not touch steering wheel while adjusting steering angle
sensor.

5.

After approximately 10 seconds, touch “END”. (After approxi-
mately 60 seconds, it ends automatically.)

6.

Turn ignition switch OFF, then turn it ON again.

CAUTION:

Do not touch steering wheel while adjusting steering angle
sensor.

7.

Run vehicle with front wheels in straight-ahead position, then
stop.

8.

Select “DATA MONITOR”, “SELECTION FROM MENU”, and “STR ANGLE SIG” on CONSULT-II screen.
Then check that “STR ANGLE SIG” is within 0

±

3.5 deg. If value is more than specification, repeat steps 3

to 7.

9.

Erase memory of ABS actuator and electric unit (control unit) and ECM.

10. Turn ignition switch to OFF.

WITHOUT CONSULT-II

Set the steering wheel in a straight forward position and drive the vehicle at 10 mph (15 km/h) or more for 10
minutes. When the procedure is complete, the SLIP indicator lamp and VDC OFF indicator lamp will turn off.

Calibration of Decel G Sensor

EFS0067M

After removing/installing or replacing ABS actuator and electric unit (control unit), yaw rate/side/decel G sen-
sor, steering and suspension components which affect wheel alignment or after adjusting wheel alignment, be
sure to calibrate the decel G sensor before running vehicle.

NOTE:
Calibration of decel G sensor requires CONSULT-II.

1.

Stop vehicle with front wheels in straight-ahead position.

CAUTION:

●

The work should be done on a level area with an unloaded vehicle.

●

Keep all the tires inflated to the correct pressures. Adjust the tire pressure to the specified pres-
sure value.

2.

Connect CONSULT-II with CONSULT-II CONVERTER to data link connector on vehicle, and turn ignition
switch ON (do not start engine).
