Porsche 996 ABS / PSM gauge light appears for no apparent reason.
Possible Causes:
- A wheel came off the ground, wheel hop from accelerating quickly at a low speed, or you hit a pothole (Solution: Turn off the car completely, then turn it back on. The ABS/PSM light will clear itself if this was the case.)
- Failed Brake Sensor (Solution: replace brake sensor)
- Failed or damaged wheel speed sensor (Solution: check datalog codes for left or right sensor failure, swap left and right sensors and see if the failure moves to the opposite side. Replace if code states failure moved to opposite side. Leave sensors alone if code doesn’t change.)
- ABS Ring on Axle (Solution: clean the ring)
- Bad Wiring Harness (Testing: Run double 16ga wire from wheel speed sensor directly to ABS box and check for code to clear itself. Solution: Order repair kit and fix harness.)
- Bad ABS Module (This is expensive and should be your last resort. Solution: Repair ABS Module ABS Repair Company
The most common problem ABS/PASM light coming on and it says it is the right front sensor with a reading out of range. If you switched the left front and right front sensors and am still getting the same fault code. Next course of action is going to be to replace the wiring going to the sensor since assuming there is a break in the wires or a short.
