AFS ECU Re-Initialization (When Using Hand Held Tester)
AFS ECU RE-INITIALIZATION (WHEN USING HAND-HELD TESTER)NOTE: This operation manually initializes the steering sensor when AFS operation is not normal due to abnormal automatic correction after completion of AFS INITIALIZATION.
HINT:
- If it is necessary to initialize the steering sensor when not disconnecting the battery, it is also possible to re-set the signal from the steering sensor.
- When the centering point memorized in the steering sensor differs from the normal point, the AFS ECU malfunctions. In the case, re-initialize it.
- If the operation does not finishes within a specified time period, the system goes off the AFS indicator lamp and starts steering neutral point automatic correction.
