Drive Authorization System (DAS)

DAS is activated from DAS control module through the Controller Area Network (CAN) data bus to the In-Line Fuel Injection (IFI) control module. When DAS is activated, IFI control module renders fuel injection system inoperative. See DAS VERSION  table to identify model/version usage.

DAS 2 activation or deactivation is accomplished with Remote Central Locking (RCL) module. System can only be activated or deactivated with Infrared (IR) transmitter or master key.

DAS 3 activation or deactivation is accomplished with Electronic Ignition (EI) lock control module when using electronic key. When electronic key is inserted into the ignition lock, DAS 3 control module is activated. Locking or unlocking vehicle using mechanical key has no effect on DAS.

On DAS systems, the IFI control module and RCL module or EI lock control module are "married" to one another with identification codes. Identification codes cannot be erased. Switching IFI, RCL or EI modules form one vehicle to another is not possible. If an exchange IFI control module is installed for test purposes, up to 40 start attempts can be performed before IFI control module and RCL or EI control modules "marry" to one another. Prior to performing first engine start, IFI control module must be version coded to vehicle using scan tool. See VERSION CODING .
