Testing ABS in 911 Carrera 4 with ABS 2LED Tester Important information on ABS of 911 Carrera

1. If any work is carried out on the hydraulic unit, speed sensors or cable harness, or if any units are replaced, e.g. during accident repairs, a function check with the ABS Tester must be performed. This prevents any mixing up of the electrical and hydraulic lines and ensures that the hydraulic unit functions correctly.

2. If a fault is indicated during operation (without any prior assembly work), diagnosing and troubleshooting with System Tester 9288 is possible.

In this case select system PDAS and read the fault memory.
