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.

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).
