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.

I’ve been experiencing several steering angle sensor problems (implausible). I recently verified the sensor, and it is in perfect condition and requires nothing. When INPA is loaded, it thinks it is centered at -55 degrees. The issue is there.
However, for some reason INPA is unable to access the DSC modules for resetting. There is nothing but values in the steering column module that can be reset. The closest choice is DSC 60, but none of the other three in INPA match what it’s searching for: DSC 60PP. Everything functioned on the 2007 sedan, therefore I believe it to be either a wagon or an LCI issue. There shouldn’t be a distinct SP Datens for the E61, and it should be sufficiently recent for LCI. Perhaps I should rename something.
Exists a different method for resetting steering angle? Or has anyone had the aforementioned issues with INPA?
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 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 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.
How is the steering assist reduced reset?
The reason behind the warning that reads “Steering Assist is Reduced, Drive With Care” on the dashboard of the car has been discussed.
Nevertheless, even if your car is in perfect mechanical condition, this notice may still appear. And occasionally, even after the problem has been corrected, it can still arise.
If, after inspection and repair, the “Steering Assist is Reduced, Drive With Care.” warning still appears, turn off your car’s engine and restart it at least two or three times. By doing this, you might be able to get the notice off your dashboard.
If this method doesn’t work, there might be a serious issue. Visit an expert mechanic to fix the problem because of this.

How does the steering angle sensor manually calibrate?
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.
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.
What location does the steering angle sensor have?
The many control modules in your car employ the steering angle sensor for a variety of purposes. How to identify a defective steering angle sensor
Numerous sensors are connected to the PCM, the vehicle’s main computer, in modern vehicles. The steering angle sensor is one sensor that monitors the vehicle’s stability and traction. The stability technology in the car—known by a number of names—is connected to this sensor.
The stability technology utilized by each manufacturer’s vehicles has a distinctive moniker, but it doesn’t change the fact that the technology is essentially the same across all manufacturers.
Why do sensors for steering angle malfunction?
Since they are made to last the lifetime of the vehicle, steering angle sensors do not typically fail, but on occasion, circumstances beyond the control of the majority of car owners can cause the sensor to wear out or fail entirely. Fortunately, there are two warning indicators that will let the driver know when the steering angle sensor has to be changed if the component is malfunctioning or failed.
The check engine light or the traction control light illuminates.
When a sensor starts to malfunction, the data it gathers or sends is likely to be erroneous, or if the sensor malfunctions, no data is obtained at all. An error code is delivered to the vehicle’s engine control module (ECM), which subsequently activates a warning light on the dashboard, if there are any anomalies in the data from the SAS being supplied to the ESC. Most cars will have a Traction Control Light as the warning indicator, however some may also have a Check Engine Light. These warning lights inform the driver that the ESC system of the car has been disabled and needs to be serviced.
- especially after an alignment or replacement of a steering component, play or irregular movement of the steering wheel
The data the sensor gathers and transmits to the ESC module will be unreliable if it is fitted incorrectly, is damaged, or otherwise fails. The EPS (Electric Power Steering) module may then supply steering input or adjustments at the incorrect moment, which will typically result in the steering wheel having more play or feeling loose. This occurs as a result of the steering input you give not being accurately sent to the wheels. The car should be sent in for a service examination if there ever seems to be a disconnect between the steering wheel and the actual steering of the vehicle.
After performing an alignment, replacing a steering component, or disconnecting or replacing the battery, vehicle repair shops frequently forget to reset or calibrate the steering angle sensor. Before putting the car on the road, be careful to confirm with the mechanic.
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
What does a BMW’s active steering entail?
The main components of the BMW active steering system are an electric actuation motor, a double planetary gear system in the steering column, and a power-assisted rack and pinion steering gear.
The double planetary gear system consists of two planetary gears, a rotating housing, an output sun gear connected to the steering pinion, an input sun gear attached to the driver’s steering wheel, and two planetary gears. The driver’s steer inputs are translated with a net 1:1 ratio if the housing is kept stationary, from the input sun gear through the planetary gears (which share a common lay shaft) to the output sun gear. In other words, if the planetary gear housing is not moved, conventional steering is still possible. In the event that the active steering system fails, this feature offers a way to maneuver the car.
A motor and worm gear can rotate the planetary gear housing, which has exterior gear teeth. The output sun gear can rotate independently of the position of the input sun gear by adjusting the housing’s position. Driving the planetary gear housing, for example, will cause the steering pinion to rotate if the driver were to keep the steering wheel (and subsequently the input sun gear) immobile (and therefore a steering action at the front wheels). The active steering ECU can create a changing steering ratio or produce steering motions independently of the driver by adjusting the location of the planetary gear housing.
Can steering angle sensors be impacted by wheel alignment?
The steering system’s various points have steering angle sensors attached to them today. The steering angle sensor may experience issues since a front end adjustment is intended to align the front wheels with the steering wheel. After completing their work, many mechanic shops frequently neglect to reset or correct the steering angle sensor. This may result in the above symptoms, such as turning on the Traction Control or Check Engine lights or impairing the vehicle’s ability to drive.
