ACC Control Module Adapting





*** FOR ADDITIONAL INFORMATION NOT INCLUDED HERE, REFER TO TSB #01950537, DATED AUGUST, 1995 ***.

^ From 1993 a new ACC control module is introduced in order to eliminate erroneous diagnostic trouble codes being generated from the rear A/C. This applies to all cars of year models M199O-M1993 with ACC2. The new control module has the following designation:
- ACC control module M1994 part number 43 82 933
- or as a spare parts kit for rear A/C: Part number 74 96 326 (contains ACC control module as above).

^ If this control module is to be fitted in cars from M199O-93 any jumper connections and resistors in the wiring harness must be removed.

Action
1. Unplug the 39 pin and the 12 pin connector on the rear side of the ACC control module.
2. Remove any jumper connections between pin 30 and pin 32 on the 39 pin connector. Insulate cable.
3. Remove any resistor between cables 23 (black) in the 12 pin connector and cable 407 (yellow/white) in the 39 pin connector. Insulate the cable.
4. Fit the new ACC control module and calibrate.
