TION
NOTICE:
Make sure to perform steering angle sensor zero point cal-
ibration when:

Replacing the steering angle sensor or ECU.

Adjusting the front wheel alignment of the steering
wheel center point in accordance with removal and
installation or replacement of the suspension, axle or

5. FOR VEHICLES EQUIPPED WITH TRACTION CON-
TROL (TRAC) & VEHICLE SKID CONTROL (VSC) SYS-
TEM
NOTICE:

When replacing the steering angle sensor or ECU, or
when adjusting the front wheel alignment or steering
wheel center point in accordance with the removing
and installing or replacing the suspension, axle, or
steering parts, make sure to perform the steering
angle sensor zero point calibration (See page
DI-252).

Do not remove or install the VSC related parts unless
necessary. Otherwise, there is a possibility that the
setting of the VSC to be affected.

When working on the VSC related operation, make
