CTEK’s guide to avoid ghost faults in the workshop
When a vehicle arrives for fault-finding or repair, the first thing you will do in most cases is connect it to a diagnostic tool, to find out where the fault is. But if the battery is not supported and has low voltage, an incorrect error code may be reported by the diagnostic tool – this is known as a ‘ghost fault’. It happens because the vehicle is trying to protect the unsupported battery, which it does in many cases by shutting down the systems it does not really need, like the radio, the air conditioning, or the start/stop function – and that is recorded as a fault.
