Notes Regarding Drive Authorization System (DAS)

Up to the end of model year 1995, a starter lock-out system is installed which interrupts circuit 50 to the starter.

On vehicles starting model year 1996 (Diagnosis Version 46), the RCL system is enhanced with a so-called drive authorization system, stage 2 (DAS). The activation of the drive authorization system (DAS) is initiated by the RCL control module and transmitted to the engine control module via the CAN data bus.

After activation of the drive authorization system (DAS), the fuel injection system is rendered inoperable by the engine control module. Therefore authorization system (DAS) can be activated or deactivated with the infrared remote control transmitter or the master key.

CAUTION: If a NEW engine control module is installed for test purposes only, a maximum of 40 engine starts can be performed before the control modules are PERMANENTLY locked with one another. After 40 engine starts, the engine control module can no longer be used in any other vehicle.

The engine control module and RCL control module are permanently locked with one another by an identification code. This identification code cannot be erased. Therefore, trial installation of an engine control module or RCL control module from ANOTHER vehicle is no longer possible.

Additionally, the code number and VIN must be entered. As of model year 1997, model 202 is equipped with an electronic ignition key. The electronic ignition key controls the activation/deactivation of the drive authorization system, stage 3, via the CAN data bus.
