The airbag clock spring connects the driver’s side airbag to the steering column and ensures that electrical contact is maintained between the airbag module and the vehicle electrical system while the steering wheel is being turned.
Also What is a Szl module?
SZL (steering switch unit) module is not the same as the steering angle sensor. … The SZL module is below the steering wheel and contains a telescoping wheel switch, a heated steering switch, a wiper switch, a turn signal, and a clock spring.
Subsequently, What is Szl in BMW? BMW Steering Switch Unit (also referred to as SZL, center steering column switch, and switch unit in the steering column) is mounted on the BMW steering column where various switches, including a wiper, turn signal, cruise control mounted. The steering angle sensor is integrated into the SZL unit.
How much does it cost to replace a steering angle sensor? The average steering angle sensor replacement cost is between $150 and $500, depending on the car model and labor costs. The steering angle sensor costs $120 – $250, and the labor costs averaging at $80 – $250.
What does a steering angle sensor do?
A Critical Safety Component
The Steering Angle Sensor is an important part of a vehicle’s safety system. It transmits the steering wheel’s rate of turn, wheel angle, and other important data to the specific vehicle’s computer. If there is a fault in the signal, the computer can disable the vehicle’s stability control.
What does a BMW steering angle sensor do?
Dynamic Stability Control (DSC) was first brought to market by BMW, the BMW steering angle sensor provides the DSC (dynamic stability control) with the overall steering wheel angle as measured by the steering angle sensor.
How do you reset a BMW steering angle sensor?
Quick Way to Reset BMW Steering Angle Sensor
Turn the steering wheel to the left and hold it there for two seconds. Turn the steering wheel to the right and hold it there for two seconds. Turn the steering to the left, then to the right one more time, then bring the steering wheel back to the center.
What happens when steering angle sensor is bad?
When the sensor is faulty, misaligned, or damaged, the information it reads and sends to the vehicle’s on board computer is inaccurate. … In most cases, this will lead to a “loose” condition in the steering wheel, where the amount of steering input you provide is not reciprocated by the action of the vehicle.
Can a steering angle sensor be repaired?
Chances are you will never crack open a steering angle sensor cluster to repair it. … To be effective at ABS and stability control diagnostics, knowing how the sensor measures angles and information is critical.
Does steering angle sensor affect power steering?
If you do try to turn your steering wheel at high speeds, your car’s computer system will recognize this as your car losing control. If you have electric power steering in your car, you might have a steering torque sensor. This sensor detects how much for a driver is putting on the steering wheel when they are turning.
Can you reset a steering angle sensor?
The procedure resets the steering angle to match the vehicle’s new thrust line after the alignment has been completed. A steering angle reset has become a necessary last step in a wheel alignment.
How do you manually calibrate the steering angle sensor?
The steering angle calibration is as simple as centering the steering wheel, turning on the ignition switch, then turning lock-to-lock starting left then right and returning to center.
What happens if steering angle sensor is not reset?
If they are not reset, the steering wheel system will not work properly. … Some cars will auto calibrate the steering angle sensors. This occurs from turning the steering wheel from lock to lock to center. There are also certain commands that need to be performed to initiate the calibration.
How do you test a steering angle sensor?
To test the SAS, you have to back probe a connector that is typically under the steering column. As the steering wheel is turned 360 degrees, the SAS produces a signal that toggles between 0 and 5 volts. As the wheel is turned lock-to-lock, the voltage will reach 5 volts three times and 0 volts three times.
Can a steering angle sensor cause limp mode?
BTW – a bad steering sensor should not cause your transmission to go into limp mode. It will affect your traction control, but even your ABS brakes should still function correctly. It just won’t intervene properly to get you out of a serious loss of traction, like taking a curve too fast on wet pavement.
How much does it cost to fix a torque sensor?
The cost of replacing the sensor can range from $350-$450 in parts and labor.

How do I reset my electric power steering?
Turn ignition switch OFF, and turn ignition switch ON. The EPS indicator comes on for about 6 seconds. Within 4 seconds of turning the switch ON, while the EPS indicator is on, turn the steering wheel 45° to left from straight ahead driving position, and hold steering wheel in position until EPS indicator goes off.
Can I drive my car if the power steering goes out?
Driving your car for extended periods without power steering fluid can damage the pump. While there’s nothing that physically stops you from driving your car if you have a power steering fluid leak, once the level drops, your pump runs dry. This causes increased friction and heat and can quickly cause expensive damage.
Do I need steering angle sensor?
Multiple sensors are required since the steering angle is critical for the stability control system, and any discrepancy could mean the difference between making it around a corner or hitting another vehicle.
How do you reset the steering angle?
The steering angle calibration is as simple as centering the steering wheel, turning on the ignition switch, then turning lock-to-lock starting left then right and returning to center.
How do I calibrate my steering angle sensor?
Calibration is normally done with a scan tool. Sometimes the vehicle will need to be on an alignment rack. The calibration process is normally done by putting the wheels in the straight forward position, and then zeroing out the sensor with a scan tool.
How do I reset my electronic power steering?
Turn ignition switch OFF, and turn ignition switch ON. The EPS indicator comes on for about 6 seconds. Within 4 seconds of turning the switch ON, while the EPS indicator is on, turn the steering wheel 45° to left from straight ahead driving position, and hold steering wheel in position until EPS indicator goes off.
