The process

How it works

  1. 01

    Connect trailer power

    We power up the trailer and establish a stable connection to the ABS system.

  2. 02

    Read ABS fault codes

    We pull active and stored fault codes to see exactly what the system is reporting.

  3. 03

    Simulate wheel speed signals

    Using in-house diagnostic equipment, we simulate wheel speed sensor signals to isolate the fault.

  4. 04

    Written repair plan

    You get a written repair plan with photos and videos before any repair begins.
