ME 9.2 Engine Control Module - New Features: This Bosch engine management system is introduced for more stringent emission requirements as well as reducing fuel consumption and increasing driving performance. A flash EEPROM is used as the storage medium for the program data, fault code memory as well as the adaptation values. The ECM works in combination with the Valvetronic Control Module. Both Control Modules control the N62 engine:

- ME 9.2 ECM - overall engine management
- Valvetronic Control Module - intake valve lift

The ECM (1) is located in the electronic box in the engine compartment together with the Valvetronic Control Module (2) and the Integrated Voltage Supply Module (3).

The ECM controls an electric cooling fan in the base of the electronic box to draw in cool air from the passenger compartment.

The 134 pin ME 9.2 ECM is manufactured by Bosch to BMW specifications. The ECM is the SKE (standard shell construction) housing and uses 5 modular connectors.




For testing, use the Universal Adapter Set (break-out box) Special Tool: # 90 88 6 121 300

Starting with the ME 9.2 system, a Multichannel Adapter Tool is used in conjunction with the DISplus to perform the complete N62 Engine Test (found under Service Functions).




The Multichannel Adapter Tool is installed (in series) between the ECM and the engine harness connectors (1, 3 and 5). In addition, the four cables of MFK2 plug into the adapter surface.
