Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Component Specifications
The component specification gives the value of the component when the connector is disconnected. Where no value is given, it is not possible to measure a relevant value at the component.
The figure within the brackets indicates the terminal pin on the component to which the value refers.
| Designation | Type | Supply voltage | Value | Other |
| Body sensor cluster stability sensor (BSC) | CAN node with integrated yaw rate sensor, lateral accelerometer and accelerometer (AWD only) | 12 V (#3) |
- | The body sensor cluster stability sensor (BSC) contains either two (2WD) or three (AWD) sensors and is connected to the brake control module (BCM) by its own CAN lead. |
| Wheel sensor | Hall sensor | 12 V (#1) | Tooth against sensor: I≈ 14 mA U≈ 9 V Cover against sensor: I≈ 7 mA U≈ 1 V below Ubat |
- |
| Pedal position sensor | Slide potentiometer | 5 V (#1) | 0 mm: ≈ 0 V 38.5 mm: ≈ 95% of Ubat |
