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.
Modify coding
Under the menu item "Modify coding" you can adapt the wiper motor control module to the current vehicle equipment.
After the wiper motor with control module is replaced, the coding must be adapted to the vehicle equipment so that the control module knows which sensor it can find on the sensor cable.
The following equipment features can be changed:
- Wiper with rain sensor
- Wiper with rain/light sensor
Vehicle coding table
| Setting | Function |
|---|---|
| Rain sensor | Automatic intermittent wiper operation |
| Rain/light sensor | Automatic intermittent wiper operation and headlight control |
- When the coding is changed in the menu item "Modify coding", the ignition must always be switched off afterwards and the key removed.
- After the ignition is switched on again, the new coding of the control module is updated and the stored faults can be erased.
- If it is not possible to communicate with the wiper motor control module in the headlight, this may be caused by incorrect coding. Remedy: Re-code the control module and restart connection setup using the Tester. Code control module correctly.
