Steering Angle Sensor Re-Calibration
Whenever maintenance or repair work is performed to the steering mechanism,
linkage, steering gear, adjustment of the wheel track, or if the steering angle
sensor is replaced, a recalibration of the Steering Angle Sensor must be
performed.
WARNING! If the Steering Angle Sensor is not recalibrated, the Yaw
Control system will not function properly, which could result in a loss
of control of your vehicle.
WARNING!
When replacing a steering wheel, use only a vehicle manufacturer
approved steering wheel and be sure that the Steering Angle Sensor is not
damaged during installation. Recalibrate the Steering Angle Sensor.
WARNING!
If replacement tires are used that are a different diameter from
the OEM-specified tire size, the new tire size must be programmed into the
ABS controller using the Bendix
®
ACom
™
Diagnostic Software.
Yaw Rate Sensor Location and Orientation
WARNING!
The location and orientation of the Yaw Rate Sensor must
not be altered.
When servicing, an identical component must be used in
the same orientation (using OEM brackets & torque requirements). During
installation follow the OEM leveling guidelines.
Understanding Your ABS Indicator Lamps
ABS Indicator Lamp
An amber ABS Indicator Lamp is typically located on the dashboard.
• At each vehicle ignition your ABS indicator lamp should illuminate as a bulb
check for approximately three seconds and then turn off. If the lamp does
not illuminate at ignition, you should have the vehicle serviced by a
qualified mechanic as soon as possible. Note: without a functioning
indicator lamp, you may not be able to determine the ABS status without
using an external diagnostic tool.
• If the indicator lamp remains on for more than three seconds after ignition,
or if it illuminates while you are driving, the ABS system may not be fully
functional or may be completely disabled. If the ABS is completely disabled
or not functioning properly, your vehicle will still have normal service braking
and it still can be driven, although without the benefits of ABS. Have the
vehicle serviced by a qualified mechanic as soon as possible to
restore full ABS functionality.
