It is recommended that the replacement aftermarket battery has the same
specifications, such as capacity and type, as the exiting battery. If the original battery is
replaced with a different type of battery (e.g. a lead-acid battery is replaced with an
AGM battery) or a battery with a different capacity (mAh), the vehicle may require
reprogramming of the new battery type, in addition to, performing the battery reset.
Consult the vehicle manual for additional vehicle-specific information.
6.5 Steering Angle Sensor (SAS) Service
Steering Angle Sensor Calibration permanently stores the current steering wheel
position as the straight-ahead position in the steering angle sensor EEPROM.
Therefore, the front wheels and the steering wheel must be set exactly to the
straight-ahead position before calibration. In addition, the vehicle identification number
(VIN) is also read from the instrument cluster and stored permanently in the steering
angle sensor EEPROM. On successful completion of calibration, the steering angle
sensor fault memory is automatically cleared.
Calibration must always be carried out after the following operations:
⚫ Steering wheel replacement.
⚫ Steering angle sensor replacement.
⚫ Any maintenance that involves opening the connector hub from the steering angle
sensor to the column.
⚫ Any maintenance or repair work on the steering linkage, steering gear or other
related mechanism.
⚫ Wheel alignment or wheel track adjustment.
⚫ Accident repairs where damage to the steering angle sensor, SAS assembly, or
any part of the steering system may have occurred.
