11.5 Replacement and repair
General safety instructions
Only qualified personnel of a specialist workshop only are authorised to perform
repair work on a vehicle.
Make sure to follow the specifications and instructions of the vehicle manufacturer.
Always comply with the company's accident prevention regulations as well as na-
tional regulations.
Use protective equipment if required.
Replacing the TEBS E Modulator
An older TEBS E Modulator can be replaced by a TEBS E Modulator of the same
or a newer version.
One exception: Modulators of version TEBS E4 and higher do not support Trailer
Central Electronics.
In most cases it can make sense to use a reconditioned modulator.

Prior to removing the old modulator the parameter set should be read out and
saved to the diagnosis computer wherever possible.
After the TEBS E Modulator has been replaced, the parameter set must be newly
written back and a start-up procedure needs to be carried out.
With TEBS E4 or higher the odometer reading of a newly installed
modulator can be increased to the actual mileage of the vehicle.
TEBS E system training or a successfully completed E-Learning course is neces-
sary for replacing the TEBS E modulator with protected parameter set. Only after
obtaining the PIN2 are you authorised to perform the replacement, see chap-
ter 11.2 ‘System training and PIN’, page 184.

g the LIN ultrasonic sensors

ter 9.3 ‘Start-up of the LIN ultrasonic sensors’, page 167.
