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 |
| Active yaw control sensor | CAN node with integrated yaw rate sensor, lateral accelerometer and accelerometer (AWD only) | 12 V (#3-#5) |
Yaw rate sensor: °/s Lateral accelerometer: m/s2 Accelerometer: m/s2 |
The active yaw control sensor either contains two (2WD) or three (AWD) sensors and is connected to the brake control module with its own CAN lead. |
| Brake pressure sensor 1 & 2 | Pressure switch (Pressostat) | 5 V (#1-#3) |
Operating range 0-170 bar 21 bar when brake pedal is not depressed |

| Pressure build-up valve | Electro magnetically controlled valve | 12 V | Pulse width modulated (PWM) signal | - |
| Wheel sensor | Hall sensor | 12 V | Tooth against sensor: I≈ 14mA U≈9V Cover against sensor: I≈7 mA U≈1V below Ubat |
- |
| Pedal pressure sensor | Two position switch | 12 V (#2-#5) NO (#1-#5) NC |
NO=Normally open NC=Normally closed |
- |
| Pedal position sensor | Slide potentiometer | 12 V | 0 mm: ≈ 0 V 38.5 mm: ≈ 95 % of Ubat |

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
