Autodata Technical Issue 8 - Electrical Fault on 2005 Mini One

29 September 2017

Each month the Autodata team answers a common technical question and provides a printable document with technical diagrams to download and keep, exclusively for IGA members. This issue solves an electrical fault on a 2005 Mini One.

Q. We are having problems diagnosing an electrical fault on a 2005 1,6 Mini One. The ABS, ASR and handbrake warning lamps come on intermittently and the speedometer and rev counter needles flicker. We have checked the fuses but my scanner won’t communicate with the ABS system. Has anyone reported this problem before?

A. Yes, this problem is common on this model and is a result of the wiring harness chafing on the ABS hydraulic modulator mounting bracket. Inspect the ABS control module wiring harness (Fig 1.1) and either repair the damaged wires if appropriate or replace the wiring harness. This should cure the problem.


To prevent a repeat of this problem, cut open a length of rubber tape and fix it to the ABS hydraulic modulator mounting bracket Fig 1.2. After repair, check for ABS trouble codes and carry out repairs as necessary.
