Command menu "ACTIVATE"

Note
When a system function is activated with the ISAT, it signifies that the TCS control module does something that is not normal from a functional viewpoint. Consequently, diagnostic trouble codes may be generated in other systems that are dependent on the TCS system.
On activation of throttle closing, for instance, an improbable TCS throttle position signal is sent to the automatic transmissions TCM control module. Similarly, on activation of "disconnect full- load enrichment" an improbable signal is sent at an improbable time to the MOTRONIC control module.

Important
The activate functions should always be used with discretion.
Activation of throttle closing results in a severe reduction of engine torque.
Activation of "disconnect full-load enrichment" causes the engine to stop.
•	Always deactivate an activated function before proceeding further in the ISAT menu.
•	When the work is finished, always clear any diagnostic trouble codes that may have been generated in the MOTRONIC or TCM systems.

	ISAT display	Function
1	THROTTLE CLOSING ON/OFF	The TCS control module closes the TCS throttle almost completely
2	TCS OFF LAMP FUNCTION ON/OUT	The TCS control module activates the TCS OFF lamp
3	DISENG CRUISE CONT FUNCTION ON/OFF	The TCS control module disengages the Cruise Control system
4	TCS LAMP FUNCTION ON/OFF	The TCS control module activates the TCS lamp and the TCS program in the TCM control module
5	DISCONN ENRICHMENT FUNCTION ON/OFF	The TCS control module sends battery + via the cable to the MOTRONIC control unit for disconnection of full-load enrichment. The MOTRONIC control module interprets this as fuel shut-off and the engine stops (used only as a wiring check).
