Description
The skid control ecu learns the steering sensor zero point every time the ignition switch is turned on and the vehicle is driven at 35 km/h (22 mph) or more for approximately 5 seconds. The ecu also stores the previous zero point.
If front wheel alignment or the steering wheel position is adjusted without disconnecting the negative battery terminal, or if the yaw rate and deceleration sensor zero point is not set after the adjustments have been completed, the skid control ecu detects the difference between the previously stored zero point and the newly learned zero point and outputs this dtc to indicate a poor adjustment.
Indication of the steering sensor zero point malfunction is canceled by turning the ignition switch off.
Inspection procedure
Notice:
When replacing the abs and traction actuator, perform zero point calibration (see page bc-24).
Hint:
Hint:
If the front wheel alignment and steering position are adjusted due to an incorrectly centered position of the steering wheel, set the yaw rate and deceleration sensor zero point again after the adjustments are completed.
Ok: the center position of the steering wheel is correctly set.

Diagnostic trouble code chart
Look for output diagnostic trouble codes (dtcs) (from the
dtc checks) in the appropriate section's diagnostic trouble
code chart. Use the chart to determine the trouble area and
the proper inspection procedure. A description of each of the
chart's columns are below.
