N3/9 | CDI control unit |
P07.16-3910-76
Location
The CDI control unit is on the air filter housing.
Tasks
The CDI control unit performs the following tasks:
Controlling the engine basic functions
Reading in of signals
Evaluation of input factors
Output of signals and actuation of components
The CDI control unit also acts as the interface (gateway) between the three connected CAN bus systems.
Controlling the engine basic functions
Fuel supply
Glow system
Injection quantity control
Electronic accelerator
Diagnosis and fault storage
Drive authorization system and immobilizer
Thermal management
Exhaust gas recirculation
Exhaust treatment
Torque coordination
Engine management Start-Stop function
Reading in of signals
Input factors are read in over the following connections:
Direct line
Drive-LIN (LIN C1)
Drive train CAN (CAN C)
Chassis CAN 1 (CAN E1)
Drive train sensor CAN (CAN I)
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.
The electronic ignition lock control unit (N73) is the central interface (Gateway) for exchanging the function-relevant data of the control units that are connected to the various CAN bus systems.
Output of signals and actuation of components
Initial parameter are output over the following connections:
Direct line
Drive train LIN
Drive train CAN
Chassis CAN 1
Drive train sensor CAN
Body
The housing of the CDI control unit is made of diecast aluminum and the cover is made of corrosion-proof sheet steel. The CDI control unit is water proof and dust proof. The inside contains the 32-bit measuring and control electronics for the engine management.
The CDI control unit has an internal atmospheric pressure sensor.
Power supply
The CDI control unit is supplied with power by "circuit 30 fused" and, with the ignition on, by "circuit 87". In the operating voltage range it has both short-circuit protection and reversed polarity protection. Power is supplied through several engaged parallel pins connected in parallel to relieve the electrical connections.
Variants
The variants of the engine management, for exampled country and exhaust variants, are activated with XD over the variant coding.
Assembly operations
Ensure before unplugging the connector on the CDI control unit that the ignition is switched off and processor run-on has ended. This is to prevent damage to the CDI control unit and save errors in the control units linked to the CAN.
Input factors and initial parameters for the following components are read in or output over direct lines by the CDI control unit and are needed by the engine management:
