Information on ABS 5.3 and ABS/TC 5.3: General

The Porsche 911 Carrera (996) is equipped as standard with an anti-lock brake system (ABS 5.3).

"Traction Control (TC)" is available on special request on the basis of ABS 5.3.

Traction Control (TC) is a combination of anti-slip control (ASR) and Automatic Brake Differential (ABD).

TC is a further system for increasing driving safety.

ABS 5.3 is optimized with regard to installed volume and weight compared with the ABS 5 (ABS 5 on the 993).

Control module (No. 1), hydraulic unit (No. 7), pump-motor relay and valve relay (No. 2) of ABS 5.3 and ABS/TC 5.3 form a unit that is located next to the brake master cylinder.
