I have a 1999 996 Carrera 4 Coupe Tip. Does anyone know if both ABS and PSM warning lights coming on at the same time signifies a specific problem or could it be any one of several causes?

:welcome:

Please give our Search a try next time as this has been discussed many times.

Two most common problems:

bad brakes light switch - check your brake lights, if they do not come on when the brake is pressed then that is likely your problem.

bad MAF - a bad Mass Air Flow sensor (or disconnected one) will also cause this.

If it is neither one of those then you will likely need a scan tool like the Durametric software, a Porsche PST2, or Porsche PIWIS tester to examine the ABS and PSM faults.

In my case, the fault code indicated a steering angle calibration error. I suspected low voltage and the problem went away when I replaced the battery. Hasn't re-occurred in the past year.
