NOTESPriority in the event of a number of faults:
Deal with fault DF020 "Computer supply voltage" first, whether it is present
or stored.
Conditions for applying the fault finding procedure to stored faults:
Apply this fault finding procedure even if the fault is stored.
Notes:
This fault does not indicate a system failure, but indicates either overheating of the
Electric Power-Assisted Steering (EPAS) motor (160˚C) or of the computer (100˚C)
during repeated manoeuvres.
This fault can occur following repeated actions on the steering wheel (parking) and
causes a reduction in the steering assistance.
Check the conformity of the battery voltage and carry out fault finding on the charge circuit if necessary.
Remove the underside of the dashboard in order to gain access to the EPAS.
Ensure (carefully) that the EPAS is not still hot.
If the EPAS is still hot, let it cool for an hour before working on it.
Make sure that nothing in the EPAS environment can cause overheating (presence of components under the
dashboard, etc.).
Repair if necessary.
After leaving the EPAS to cool (PR008 Computer temperature and PR009 Steering motor temperature less
than 30˚C), clear the fault, start the engine and check that the EPAS is operating correctly by repeatedly carrying
out parking manoeuvres (turn the wheel slowly from the right-hand to left-hand lock positions).
Check that PR014 Level of assistance available = 100%.
If the fault is present once more or is stored after just a few manoeuvres, contact Techline.
AFTER REPAIRClear the stored faults.
Check that the EPAS is working.
Deal with any other faults.
