9-5 Linear Sport Wagon (9600) L4-2.3L Turbo (B235) (2002)
The ABS Control module sends a speed signal to pin 64 on the Trionic 17 Control module. The signal is a square wave that varies between 0 V and B+
29 times per wheel revolution. This speed signal is used to:
-
prevent adaptation of idle speed Control when the car is moving.
-
on manual gearboxes, determine which gear is currently being used. This makes it possible to limit torque in gears R and 1 and activate Fuel
shut-off in gears 2, 3, 4 and 5. Control of the SHIFT UP lamp also depends on the current gear.
-
activate speed limitation, which is achieved by limiting the maximum air mass/combustion at 240 km/h.
Diagnostics
-
If the speed signal is missing, diagnostic trouble code P0502 will be generated.
-
If the speed value is implausible, diagnostic trouble code P0501 will be generated.
System reaction to a fault
-
Speed (bus from MIU) used as substitute value.
