The vehicle may use either a sealed lead-acid battery or an AGM (Absorbed Glass Mat)
battery. Lead acid battery contains liquid sulphuric acid and can spill when overturned.
AGM battery (known as VRLA battery, valve regulated lead acid) also contains sulphuric
acid, but the acid is contained in glass mats between terminal plates.
It is recommended that the replacement aftermarket battery has the same specifications,
such as capacity and type, with the battery used in the vehicle. 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 the new battery type in addition to performing the battery reset. Consult
the vehicle manual for additional vehicle-specific information.
7.4 Steering Angle Sensor (SAS)
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 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 or assembly, or any
part of the steering system may have occurred
NOTE
1. Autel accepts no responsibility for any accident or injury arising from servicing the
SAS system. When interpreting DTCs retrieved from the vehicle, always follow the
manufacturer’s recommendation for repair.
2. All software screens shown in this manual are examples, actual test screens may
vary for each vehicle being tested. Observe the menu titles and on-screen instructions to
make correct option selections.
