GF80.57-P-6000GZ Electronic Ignition/Starter Switch Control Unit (EIS), Component Description







Location
The EIS control unit is located in the cockpit on the right next the steering column below the instrument cluster (A1).

Task
- Drive authorization functions according to drive authorization system stage 3 (FBS 3)
- Control of central locking (CL)
- Infrared (IR) communication with transmitter key (A8/1) in inserted state and inductive energy transmission onto transmitter key
- Transmission of request data (key identification) for releasing the ME-SFI control unit (N3/10) and the intelligent servo module for DIRECT SELECT (A80) according to DAS 3
- Rotation-angle dependent activation of circuits 15R, 15, 50
- Output of terminals to controller area network bus class C (engine compartment) (CAN-C) and controller area network bus class B (interior compartment) (CAN-B)
- Locking transmitter key in turned position
- Transmitter key returns from start to drive position
- Prevention of turning an invalid transmitter (rotary lock) (up to 31.5.07)
- Assignment of transmitter key to memory functions
- Key-P-function: When the transmitter key is removed, the EIS control module requests the intelligent servo module for DIRECT SELECT to shift to drive stage "P" via the CAN-C

On vehicles with code (889) Keyless Go:
- Key-P-function:
When the driver door is open, the EIS control module requests the intelligent servo module for DIRECT SELECT to shift to drive stage "P" via the CAN-C.
- Interface to keyless go control unit (N69/5) via CAN-B for keyless go access and keyless go operation
- Holding and reading in start/stop button for keyless go operation

General information:
- The limit switch for c. 15R and c. 15 are not installed in the EIS control unit. The rear SAM control unit (N10/8) switches c. 15R and the front SAM control unit (N10) switches c. 15.
- The "Keyless lock function" is replaced with "key-P function".
- The "Remote door unlock" function is enabled in the EIS control unit by variant coding
- The EIS control unit is not a gateway.

As of 1.6.07 the rotary lock in the EIS control module is eliminated. It is not possible to active any terminals with an incorrect transmitter key or a transmitter key which is not functioning properly. The note "Key does not belong to vehicle" appears in the instrument cluster.
