What is the issue with the terminal 30 power supply voltage of the Audi steering angle sensor?
1 Answers
Voltage does not reach the specified value, especially when the car has no power or after replacing the battery, an alarm appears. The alarm will automatically disappear after driving the car for a while, completing the basic setting of G85. Below are the relevant precautions: 1. Steering wheel alignment: When replacing the sensor or steering column, ensure the steering wheel is aligned, the ignition switch is on, but the engine is not started. 2. Counting increase and decrease: When turning in one direction, the count increases; when changing the turning direction, the count decreases. The count is related to the initial position of the angle sensor. When initializing the angle sensor, the count value is set to 0. If necessary, it can be reset via programming. 3. Adverse effects: To ensure the sensor's accuracy and sensitivity, and to avoid indirect changes in dielectric constant, plate shape, etc., due to factors like environmental temperature, which could adversely affect the sensor's performance.
