This might be beneficial.
1) Short out Pins 4 (CG) and 12 (Ts) on the OBDII (DLC3) connector located underneath the steering wheel.
2) Do not start the engine after turning the key to the ON position.
3) Before attempting calibration, verify that the steering wheel off center angle is no more than 3 degrees from the center (In otherwords – Center the damn Steering wheel)
4) Put the car in park (That should be the default, right?)
5) Depress the brake pedal three times in two seconds while pressing and holding the TRAC OFF switch.
6) Hold the TRAC OFF switch in place until you hear the VSC buzzer (repeated beeping).
7) Turn off the TRAC switch. The VSC buzzer will continue to chime for three seconds after the procedure is finished as confirmation.
HINT: If the operation is carried out properly and the VSC alarm does not sound, there may be a $300 steering angle sensor issue.

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. You can follow the step-by-step instructions to get through.
What happens if you don’t reset the steering angle sensor?
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.
Will the steering angle sensor be reset if the battery is disconnected?
Most of the time, sure. The electronic control unit (ECU) will reset and erase any stored codes when the battery is disconnected. This also contains the steering angle sensor codes.
The code will probably reappear once you reconnect the battery, though, if the issue that led to the code’s storage in the first place is not resolved. This is why it’s crucial to have your vehicle inspected by a mechanic so they can identify and resolve the issue.
Do steering angle sensors require programming?
Depending on the automobile model and labor expenses, the replacement cost of a steering angle sensor ranges from $150 to $500. The labor costs average $80250, while the price of the steering angle sensor is $120250.
When you look at the replacement cost, the first thing you may notice is how widely it differs. Both the part’s fixed cost and the labor cost are not fixed. There are various causes for this. First off, the model year and brand of your car might affect how much the item costs.
You must be aware that to get this task completed for you, you must locate a mechanic who has the necessary diagnostic equipment. The steering angle sensor needs to be calibrated after being replaced.
Some steering angle sensors are built within the steering column control unit, therefore they require programming into the vehicle. However, this is not common. However, programming it will be significantly more expensive if such is the case.
How is the steering angle sensor tested?
You must back probe a connector, which is normally found under the steering column, in order to test the SAS. A signal that alternates between 0 and 5 volts is generated by the SAS as the steering wheel is rotated 360 degrees. The voltage will alternate between 5 volts and 0 volts three times while the wheel is rotated from lock to lock.
How is electric power steering calibrated?
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 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.
What signs would point to a bad steering angle sensor?
The initial warning symptoms of a faulty steering angle sensor could be difficult to detect or extremely obvious. The steering angle sensor may be to blame if you observe anything unusual or any of the following problems.
Check Engine Light
The check engine light, especially in older vehicles, may illuminate as your first sign of a problem with the steering angle sensor. Initially, the check engine light was connected to all electrical control systems in automobiles.
Traction Control Light
The steering angle sensor is connected to the traction control system, much like the check engine light is. The traction control light, ABS light, or even the airbag light may turn on if the traction control system receives the wrong signal.
Strange or Awkward Steering after Wheel Alignment
If the automobile was just serviced and the steering feels weird or off now, it can be the fault of the mechanic. The steering angle sensor’s signals will be unreliable after realigning the wheels without first resetting the sensor.
Variations in Steering Boost
There is a problem with the steering angle sensor if the steering sensitivity fluctuates within a turn. The steering may feel overly sharp and tight one moment and too lax and forgiving the next.
After alignment, does the steering angle sensor need to be reset?
The steering angle sensor (SAS) in more than 40 million vehicles on the road today needs to be reset or recalibrated after a wheel alignment, per instructions from the vehicle’s manufacturer for some vehicles with electronic stability control (ESC).
The steering angle sensor (SAS) in over 40 million vehicles on the road today needs to be reset or recalibrated after a wheel alignment, per the manufacturer’s instructions for some vehicles with electronic stability control (ESC). Since all automobiles made for US consumption starting in 2012 have an ESC, this number will only increase. After the alignment is finished, the method adjusts the steering angle to correspond to the vehicle’s new thrust line.
The final step in a wheel alignment procedure now always includes a steering angle reset. While it is possible to conduct this task with several OE style scan tools, an integrated solution is much more effective. Hunter’s CodeLink offers a straightforward, integrated solution that takes care of the OEM-specific reset needs. In order to align safety system-related sensors with the car’s alignment geometry, CodeLink “connect the vehicle OBD-II system to the aligner.” The software recognizes the car as a candidate for reset after it is registered into the system. Hunter’s WinAlign program connects with CodeLink to make the process simple.
Some vehicles’ complete steering angle sensor resets also include torque angle sensors and yaw rate sensors. Without further assistance from the technician, CodeLink manages any sensor resets directed by the vehicle’s manufacturer. CodeLink also offers the same user interface the technician used to complete the alignment while replacing a number of OEM scan instruments. Simple reset instructions can be used in place of the complex OEM procedures often associated with a scan tool sized screen when communicating with the technician using the alignment system’s full size screen.
The steering system reset was properly carried out, according to printed documentation provided by the Hunter Aligner. Hunter WinAlign alignment units are included as standard equipment with CodeLink.
Failure to perform a safety system alignment when required may impact the proper operation of electronic driver-assist systems.
As a result of the steering angle sensor’s unknown position following a wheel alignment, several OEMs now demand safety system alignments or safety system resets.
How can I turn my power steering light back on?
All you have to do to get the light to reset is to turn off and restart your engine. Most of the time, it should turn back on, and this just shows that it might have believed there was a problem because of an error in the computer system.
Steering is affected by the ABS sensor?
Vehicle handling and steering are improved with electronic stability control. The vehicle’s acceleration, steering, and acceleration changes are tracked by the abs computer in order to achieve this. Several sensors, notably the wheel speed sensors, contribute to this knowledge.
What causes an off-center steering wheel?
Even though your wheels are straight, you will notice that your steering wheel is out of center, meaning the logo is not straight, when your wheels are not properly aligned. Pulling is yet another obvious indication that your car is out of alignment. Even though you may be going straight, your car continues veering to the left or the right, giving you the hassle of having to correct it all the time. Because the misaligned wheels are bouncing around on the road’s surface, your tires may also wear unevenly.
Can I adjust my automobile on my own?

In order to align the wheels so that they are parallel to one another and perpendicular to the ground, the angles of the wheels must be adjusted. As a result, your tires will last longer and you will be able to drive straight on the road. Your automobile can veer to the right or left if your front end is out of alignment.
Adjusting the caster, camber, and toe will align the front end. The steering axis’s forward or backward tilt, as seen from the side, is known as the caster. Your wheels’ inclination, whether seen from the front or the back, is known as camber. The toe is the amount of inward or outward movement of the front of your wheels as viewed from above [source: Grassroots Motorsports].
A front-end alignment will help with any tugging or unevenness you feel in the steering if your automobile is front-wheel drive, as the majority of vehicles currently are. However, a lot of vehiclesespecially SUVs of all sizeshave all-wheel drive. This requires front and back alignment at the same time, which is normally best left to the experts. Auto Quarterly, cited
It’s preferable to have a skilled car mechanic perform a good wheel alignment on your vehicle, regardless of the type. On a front-wheel drive vehicle, you might try to do it yourself with the necessary equipment. This is how:
- Using jack stands, raise the front wheels both.
- To make the steering wheel move, turn on the electrical system but leave the engine off. On the ignition, this is sometimes designated as a “accessory.”
- Observe the car’s front wheels one at a time. Verify the direction that it is pointing. The outer tire rod needs to be tightened if it is pointed inward toward the center of the vehicle. You need to loosen the tire rod if it’s facing outward.
- The nut holding the outer and inner tire rods together can be loosened. This will enable you to adjust the tire rod’s tension.
- If the wheel needs to be turned more inward, the outer tire rod must be turned counterclockwise or loosened. The tire rod should be tightened or twisted clockwise if it has to be turned further outward.
- After making the correction, immediately turn the wheel to see if the wheel is still tilted incorrectly. Repeat the process with the other wheel if the first one is straight.
The front-end alignment and wheel alignment differ primarily in that the front-end alignment concentrates on the front two wheels while the wheel alignment is performed on all four.
