- Electronic accelerator

- Drive authorization system and immobilizer

-----------------------------------------------------------------------------------------

- Alternator interface

- Regulated camshaft adjustment

- Fuel supply

- Torque interface

- Engine control, start/stop function

- Direct line

- Drivetrain LIN (LIN C1)

- Drive train CAN (CAN C)

- Chassis CAN 1 (CAN E1)

-----------------------------------------------------------------------------------------

Evaluation of input factors

The input factors that have been read in are evaluated by the integrated microprocessor and the affected components are then actuated.

Output of signals and actuation of components

Initial parameter are output over the following connections:

- Direct line

- Drivetrain LIN (LIN C1)

- Drive train CAN (CAN C)

- Chassis CAN 1 (CAN E1)

The electronic ignition lock control unit (N73) is the central interface (Gateway) for exchange of function-relevant data for control units which are connected to the various Control Area Network (CAN) bus systems.

Design

The housing of the ME-SFI [ME] control unit is made out of diets aluminum and the cover is made out of corrosion-proof sheet steel. The ME-SFI [ME] control unit is protected against water and dust.

The housing contains the 32-bit measuring and control electronics for the engine control.

Power supply

The ME-SFI [ME] control unit is "circuit 30 fused" and also supplied with a voltage for ignition ON by "circuit 87 M4" .

In the operating voltage range it has both short-circuit protection and reversed polarity protection.

Power is supplied through several pins connected in parallel to relieve the electrical connectors.

Ground connection

The ground connection "circuit 31" is made over a number of ground lines to the front right ground point for lamp unit (W2).

No-load current shutoff

Information for partial function "no-load current shutoff" is documented in the function description "Energy management engine OFF function".

Variants

The engine control variants (e.g. national and exhaust variants) are activated with Xentry Diagnostics using the variant coding function.

Replacement of the ME-SFI [ME] control unit is not necessary.
