ESP, Electronic-Stability-Program Bosch 5.3

Encoding control unit

After installation of a new control unit -J104 or a new steering angle sensor -G85 the ESP system must be encoded again. After encoding the steering angle sensor compensation must be performed.

Encoding of ESP control unit is designed to adapt the control unit to the vehicle.

Zero position compensation must then be performed for steering angle sender -G85.

Coding is only possible after the workshop code (WSC) has been entered into V.A.G 1551.

Note:

If control unit has been encoded with code 00000 or with a code not appropriate to the vehicle the ABS warning lamp (K47) and the TCS/ESP warning lamp (K86) will light up continuously and the fault 01044-Control unit incorrectly codedwill be stored in the fault memory of the control unit.

The brake caliper type must be determined in order to perform the login procedure and the encoding (see illustrations below).
