Porsche Dashboard Warning Lights and Symbols

Porsche Anti-Lock Brake System Fault Indicator

Anti-Lock Brake System Fault Indicator

If the ABS warning light illuminates while the engine is running, the system is malfunctioning. If ABS is not working properly, the brake system then operates without using ABS. The ABS prevents the brakes from locking up during hard braking. Take caution not to brake too hard while the ABS system is malfunctioning. Use an ABS scanner to diagnose problems with the system.

Common ABS faults:

  • Faulty or contaminated ABS ring or sensor
  • Faulty ABS module 
  • Warped rotors
  • Contaminated brake fluid

Porsche Service Engine Soon Indicator

Check Engine Light / Service Engine Soon

The service engine soon lamp means a fault has occurred in one of the various vehicle systems. It will only turn on when a vehicle has recognized there is a significant enough problem that it needs to be serviced. A code will be stored within the vehicle's computer to give more detail on the problem at hand. Follow this guide to scan the vehicle's computer for trouble codes to see why the check engine light has turned on.

If the light is steady, it is normally okay to drive for the time being. Do NOT drive the vehicle if the check engine malfunction indicator light (MIL) is blinking. This is usually a sign of misfire and oftentimes catalytic converter failure, which can lead to massive engine failure if driven. 

Common causes of the service engine soon indicator:

  • Loose fuel cap
  • P0420 catalytic converter failure
  • Emission control system failure
  • O2 sensor failure
  • Dirty Mass Air Flow (MAF) sensor

Porsche  Air Bag Warning Light

Porsche SRS AIRBAG LIGHT

 Air Bag Warning Light

When the vehicle is first turned on, this warning light will illuminate for approximately seven seconds. If the light stays on while the engine is running, the vehicle's safety restraint system needs to be serviced.
