9-5 Linear (9600) L4-2.3L Turbo (2.3t) (2004)
Function
When the ESP or TCS function is activated, a bus message sent by the ESP control module lights up a lamp on the main instrument unit. The lamp
extinguishes as soon as the function cuts out.
For the lamp to light requires both braking and a reduction of engine torque. This means that the system can in some circumstances function without
the lamp lighting.
Diagnostics
The function has no diagnostics.
