Communication With ACS

If the car is equipped with an ACS (Sensonic), the Saab Information Display (SID) receives information on the system via pin 6.
Communication is of single-wire data link type. The following messages can be displayed:

- "DISENGAGE GEAR"
Displayed if input shaft speed exceeds 7000 rpm after changing gear or if neither the brake pedal nor the accelerator is depressed when the car is stationary with a gear engaged. This message is also displayed if an attempt is made to start the engine with a gear engaged or with reverse gear engaged and the brake pedal not depressed.

- "SHIFT DOWN"
Displayed if input shaft speed is less than 850 rpm after changing gear.

- "OVERHEATED CLUTCH"
Displayed when the clutch is overloaded (overheated).
