Retrofit

Procedure for retrofitting systems requiring programming or coding in the model series

E31, E32, E34:

• Read out vehicle data with ISTA/P.

See Section: Starting new session with ISTA/P

Select "Coding ZCS/FA"

• Select model series (e.g. "E34")

• Select "2 - Retrofit"

• Select system (e.g. "1 - Air conditioning system (IHKR II/III)")

• Start automatic encoding (confirm with "Y")

• Follow the instructions given by the user prompts.

Conversion

Procedure for conversion of systems relevant to programming or encoding:

• Read out vehicle data with ISTA/P.

See Section: Starting new session with ISTA/P

Select "Coding ZCS/FA"

• Select model series (e.g. "E34")

• Select "4 - Conversion".

• Select system (e.g. "1 - Antitheft alarm system")

the basic status when newly encoded.

Calculating 5-character IBAC enable code

The 15-character IBAC enable code must be converted into a 5-character IBAC enable

code on vehicle model series that are processed via SGC (E31, E32, E34).
