These procedures can be used to quickly calibrate the steering angle sensor on a BMW.
- Start the car’s engine while keeping it in park and applying the parking brakes.
- Hold the left turn of the steering wheel for two seconds.
- Hold the right turn of the steering wheel for two seconds.
- The steering wheel should be turned once to the right, once to the left, and once again to the middle.
This process alone will typically calibrate the steering angle sensor. If the above steps are unsuccessful, you will need to calibrate the steering angle sensor on a BMW using a diagnostic scanner.

What does a steering angle sensor on a BMW do?
The steering angle sensor is a crucial component of the safety system in a car. It sends crucial information, including the steering wheel’s rate of turn and angle, to the computer of the particular vehicle.
What occurs if a steering angle sensor malfunctions in a BMW?
Traction Control is one of the common indicators. After a front end adjustment, a light turns on, the steering wheel feels slack, and the car drives differently.
How is the steering angle sensor initialized?
- The steering angle sensor needs to be initialized before the DSC can function, which could result in an unanticipated collision. Therefore, if the power supply to the steering angle sensor has been cut off owing to disconnection of the steering angle sensor connector or negative battery cable, or for any other reason, always conduct the initialization procedure to assure DSC operation.
- Battery power is needed by the steering angle sensor to store the steering angle’s starting position. Consequently, a stored steering angle initial position is cleared when the battery power source is interrupted.
1. Examine the condition of the steering wheel’s installation, tire pressure, and wheel alignment.
Adjust the relevant part if there is a problem.
2. Join the battery’s negative cable.
3. Insert the ignition key into the ignition.
4. Verify that both the DSC indication light and the DSC OFF light are on.
5. Fully lock the steering wheel to the right, then fully lock it to the left.
6. Verify that the DSC OFF light disappears.
7. Disconnect the ignition switch.
8. Check to see if the DSC indicator light turns off by turning the ignition switch back to the ON position.
- Disconnect the negative battery cable and repeat the process, starting from Step 2 as stated above, if the DSC indicator light does not go off.
9. After about 10 minutes of driving, check to see if the DSC and ABS warning lights are not on.
How is the steering angle sensor calibrated?
By measuring the steering angle and comparing it to the route of the vehicle, the steering angle sensor can identify an understeer condition.
On several Mercedes-Benz vehicles from the previous ten years, for instance, is a nice illustration. The ignition switch must be turned on, the steering wheel must be centered, and the steering wheel must then be turned lock-to-lock beginning with the left and ending with the right before returning to the center.
But if you follow the right steps, you have to calibrate the entire system. For this, the yaw, lateral, and longitudinal accelerometer sensors must be calibrated. A factory or upgraded scan tool, an adaptive drive, or both could accomplish this.
Calibration of the sensors is essential for the proper operation of safety technologies like adaptive cruise control, lane departure warning, and pre-braking on Mercedes-Benz automobiles.
Do steering angle sensors require programming?
The steering angle sensor needs to be calibrated after being replaced. A few steering angle sensors are built within the steering column control unit, therefore the vehicle needs to be programmed with their settings.
How is the steering angle sensor reset?
You will get a notice that says to turn the ignition key off and wait for at least five seconds if you enter the Wheel Alignment System, choose Wheel Alignment, then Reset Memory. Press the brake pedal and start the engine when five seconds have passed. The detailed directions will lead you through
Without a scanner, how do you reset a steering angle sensor?
- Start the car.
- Completely turn the steering wheel to the left.
- Completely turn the steering wheel to the right.
- Steps 2 and 3 should be repeated once more.
- Return the center of the steering wheel.
- short, straight-line distance to travel
What signs would point to a bad steering angle sensor?
- Check engine light, first.
- Traction Control Light Number 2.
- 3. Fighting or weak steering.
- 4) After wheel alignment, strange or awkward steering.
- 5) Changes in the steering boost.
- 1) Poor wiring.
- 2) Not Resetting After Alignment
- 3) Serious Errors
Why is calibration necessary for steering angle sensors?
The steps necessary to keep advanced driver assistance systems (ADAS) operating safely following an accident should be known to technicians. Checking for diagnostic fault codes or directing a camera, which can make a system not work as intended (DTCs). We’ve put together a series of articles that offer general information on what is necessary to fix the system after a collision to give you a basic idea of what is needed. The steering angle/position sensors will now be discussed.
Normally, steering column sensors for steering angle and position are included. The sensor keeps track of the steering wheel’s direction of rotation. Systems like lane keep assist, blind spot recognition, and adaptive lighting are all controlled by the steering angle sensor. Following an airbag deployment, structural repairs, or wheel alignment, steering angle sensors may require calibration.
A scan tool is typically used for calibration. The car may occasionally need to be placed on an alignment rack. The wheels are typically set in the forward position before the sensor is zeroed out using a scan tool to complete the calibration process.
A thorough, secure, and high-quality repair depends on having knowledge of these systems. For these driver assistance features, a lot of people choose a particular car. The customer is aware of the system’s presence in their car and relies on it to keep them safe. As a result, technicians must be knowledgeable about driver aid systems and be aware of their existence.
How much does a steering angle sensor replacement cost?
The overall cost to replace a steering angle sensor ranges from $120-$550 on average. The cost of the sensor varies from $50 to $400, while labor will cost you $75 to $150.
Like other sensors, the price of the part might differ significantly based on the type of sensor, the year, make, and model of the car, as well as whether it is an OEM or aftermarket part.
As opposed to going to a dealership, you’ll nearly always spend less getting this part changed at an independent car repair shop.
Although DIY replacement is possible, it is typically advised to let the experts handle this task because you will need to work around the airbag system and will need specialized equipment, such as a steering wheel puller.
What happens if you don’t reset the steering angle sensor?
Because of this, the vehicle’s stability control system may modify the steering inadvertently, which could lead to a loose steering wheel or an improper response from the steering.
Will the steering angle sensor be reset if the battery is disconnected?
The steering angle sensor must be initialized before the Dynamic Stability Control (DSC) system of the Roadster can function. There are a variety of circumstances that could lead to the loss of this calibration information, which is maintained electronically. The most typical one is when the steering angle sensor loses power because the battery was disconnected for an unrelated reason (or the battery going flat).
- Disconnection of the negative battery cable
- Disconnection of the steering angle sensor connector
- Fuse removal for the 15A ROOM
- disconnecting the steering angle sensor connector from the wiring harness between the battery
The DSC warning light will turn on and the DSC OFF light will flash while you are parked if your car’s system needs to be reset. The steps to reset are as follows:
- Switch the ignition to “ON”
- Verify the DSC light is on and the DSC OFF light is flashing.
- Turn the steering wheel all the way to the left, then back to the right.
- Verify DSC The flashing OFF light stops and turns off.
- turn off the ignition
- Reset the ignition switch to ON.
- Verify that the DSC light is not on.
- Disconnect and re-connect the battery negative line and try the process again if the DSC light doesn’t go out.
How is the steering assist reduced reset?
Imagine that the Steering Assist Is Reduced Drive With Care warning appears on the instrument panel of your car. The power steering system isn’t operating properly in that instance. Driving carefully is vital because this may make it challenging to drive the car.
To reset the alert, you must first turn off the power steering system and then turn it back on. The usual way to do this is to restart the car after switching the ignition key to the “OFF” position.
If the warning light reappears, you might need to take your automobile to a qualified mechanic for additional evaluation and repair. Drive cautiously in the interim, paying attention to your speed and braking. You should be able to arrive at your destination safely if you exercise some caution.
How can code u0126 be fixed?
The battery in your car should be changed or fixed. You need swap out or fix your SAS control module. Make that the SAS module in your car is receiving power and replace or fix any faulty wiring or circuits. Any malfunctioning or out-of-date software in your car should be replaced or reprogrammed.
Why does code U0073 exist?
If your car displays a U0073 engine code, it implies that the modules in your car are no longer in communication with one another. The powertrain control module (PCM), which controls the engine, receives data from the modules about your car’s performance over the controller area network (CAN) bus.
Your car uses diagnostic trouble codes (DTC) to communicate the type of issue or malfunction. An OBD-II code reader can be used by you (or your mechanic) to view the DTCs. Once you are aware of a DTC’s definition, you may assess the situation and choose the best course of action.
How can I resolve the c1219 error?
check for wheel alignment Calibrate the steering wheel sensor (see GROUP 35C – On-vehicle Service) and set the AWC-ECU steering angle correction amount after testing the wheel alignment (Refer to )
What does C123F stand for?
I installed the rack, and right away I received the code and warning light. When I turned the wheel just a little bit past center in either direction, it first switched on the code and light. It no longer shows me the code and light unless I turn the wheel more than one complete round to the right after a few full stop to stop turns.
The steering column angle sensor’s signal may not be working properly, according to code C123F. The signal is lowered and raised by rotating the steering wheel in a clockwise or counterclockwise direction, respectively. To verify for correct signal generation, you will require a scan instrument coupled to the diagnostic port. The clock spring wiring assembly under the horn pad is where the steering angle sensor is attached.
You might not get a response because this is an old thread, and you might be restarting an old thread. Consider starting a new thread, please.
Why does U0100 code appear?
What the U0100 Code Indicates “Lost Communication with ECM/PCM ‘A.'” is the meaning behind DTC U0100. When communication between your PCM and a specific module is lost, it is activated. If you don’t take care of the problem that caused the code to appear after it occurs, the car can shut off and not start again.
