Ford C-max and Grand C-max electrical power steering rack faults

Ford C-max and Grand C-max electrical power steering

rack faults


The Ford Cmax and Grand C-max 2nd generation from 2011 onwards, uses an electric steering rack. The electric rack used on the Mk2 C-max appears from experience to suffer from a very high failure rate.

The symptoms are usually either a complete and sudden loss of power steering and a power steering assist failure message on the vehicles info screen, sometimes this loss of assistance is intermittent whereby the steering will fail to initialise when the car is first started and then come back within a few seconds.

If the fault codes are then read on a scanner, the usual fault code is a generic U3000 followed by a specific 2 digit code of usually 49 or 53. the U3000 code is a failure of the steering rack control unit to communicate with the vehicle , the 49 or 53 relate to either an internal electronic component fault or a failure to initialise with the vehicles body control computer.

The only long term solution to this fault is to replace the steering rack, we can supply a remanufactured rack that we have rebuilt with new components and then programmed with the latest software to prevent a repeat failure.

The racks we supply will self-code to the car and do not need any coding/programming to work correctly.
