Hello,
While there are some threads on this issue I think more detail is required.
As with I think nearly all mk2 Panda, bar maybe the really early and non power assisted cars, my 1.3D 4x4 cross has the electric power assistance fitted, this is quite a standard unit used in the Panda and 500, plus some fords and other makes too.
While this unit is more power efficient than a mechanical PAS, it is delicate and far more complex and expensive to diagnose -As I am now finding :-(
The trouble is even quite well versed garages also have no idea how this thing works and cannot repair more than total replacement of the unit.
Mine is has started turning on and off, which is disconcerting when driving and brings up the consult manual error and EPS error light, the error then goes of and it returns to function, swapping between the two, though once warmed up tending to then work ok'ish
I have consulted the Panda service CD, and faults fall into 4 areas, poor power connection (it is driven directly off the battery with its own cabling), the torque sensor (a cheaper part, but will need calibration), the motor drive itself and finally the control unit M086.
My garage is advising, my error is the control unit M086, as when on test it advises its input voltage is 16.5v, while at other points in the car it is at 14v (which is normal when running). I am unsure how it can read at this level so my garage is advising to replace this unit. However as the cross has some unique features, this otherwise common control unit is only available from £700 from Fiat :-(
Does anyone have experience with this steering unit or has the circuit diagram from me to follow for it? I only have the block diagram :-(
