For a fault with the switch then clear the code , ign off then on and dont touch the brake pedal .. there should be no warning and no fault code generated .
Press the brake pedal or drive the car and the code should come back as before .
There is the wiring and the psm control unit that can be faulty .. not just the switch .. im not sure what code number you have or age of car / type of psm but i dug out some details that might help ..
But it is from an early car ..
Thanks DeMort, it is a 2002 996.2 C4 Cab.
All wheel sensors are showing continuity to ECU and we have spun the wheels and have been getting a pulse.
Car is fitted with an LED 3rd brake light and have disconnected that, but it is still showing an ABS/PASM light when driving.
The fault code is the same as in the checklist (brake light switch) I will however confirm when I put a tester on it again. Is the checklist ok for 2002 2 gen cars?
