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.
Extract and change coding
- After the trailer hitch control module is replaced, the coding must be customized to the vehicle equipment so that the control module knows which trailer hitch is installed and which functions are desired or necessary.
- Automated folding/pivoting is synonymous with comfort closing in power windows. Touching the button is sufficient to fold/pivot the trailer hitch.
- The 'No automatic folding/pivoting' option can be coded if there are doubts about safety. The button must be kept pressed until the trailer hitch is completely retracted or extended.
- With or without operating button; the operating button must be activated for the outwardly pivoting trailer hitch. This is of course not necessary for the detachable trailer hitch.
Versions or equipment features can be read out and reactivated under the 'Coding' menu item.
The following options are possible:
- USA/North America
- RoW
- Trailer hitch with detachable ball head
- Trailer hitch with automatic unfolding/pivoting of the ball head - "comfort folding"
- Without automatic folding/pivoting of the ball head - switch/button must be held
- When the coding is changed in the "Coding" menu item, 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.
