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.

PROGRAMMING THE STEERING WHEEL ANGLE SENSOR
DEF: Programming not carried out or incorrect
NOTESNotes:
This fault is present for as long as the steering wheel angle is not calibrated.
It is automatically cleared as soon as the programming procedure is completed.
This fault causes an absence of steering wheel recall (with warning light
continuously on).
Place the vehicle on a front axle adjusting bench.
Position the vehicle wheels in the straight line driving position (steering centre point).
Program the steering wheel angle via command VP004 Steering wheel angle sensor programming
(see Configuration and programming, section A).
Vehicle in straight line driving position (steering centre point).
Refer to parameters PR121 Steering wheel angle and PR007 Steering wheel angle offset compensation.
Both parameters must be 0˚.
Turn the steering wheel to full right lock then to full left lock, and check that the parameter varies within the
tolerances given in the conformity check.
Refer to status ET020 Steering wheel angle sensor programming, which must be STATUS 4.
Start the engine and check the operation of the EPAS by turning the steering wheel from lock to lock
(parking manoeuvres).
If the fault is still present, contact the Techline.
AFTER REPAIRClear the stored faults.
Check that the EPAS is working.
Deal with any other faults.

STOREDANGLE SENSOR
1.DEF: Sensor internal electrical fault
2.DEF: Absence of sensor signal
3.DEF: Values outside limits
NOTESConditions for applying the fault finding procedure to stored faults:
The fault is declared present after having started the engine and turned the steering
wheel from lock to lock.
Notes:
This fault causes an absence of steering wheel return (no warning light or message).
–The computer records an occurrence context (computer operating values frozen
when fault occurs). To view this information, click on the fault description (camera
symbol). Within these values, parameter PR143 Internal fault code gives the fault
finding procedure to apply.
Procedure to apply for internal fault codes 195 and 196 of PR143.
Position the vehicle wheels in the straight line driving position (steering centre point).
Refer to parameters PR121 Steering wheel angle and PR007 Steering wheel angle offset compensation.
Both parameters must be between - 10˚ < X < 10˚.
Turn the steering wheel to full right lock then to full left lock, and check that the parameter varies within the
tolerances given in the "Conformity check".
Refer to status ET020 Steering wheel angle sensor programming, which must be STATUS 4.
If parameters PR121, PR007 and status ET020 are not correct:
Place the vehicle on a front axle adjusting bench.
Position the vehicle wheels in the straight line driving position (steering centre point).
Program the steering wheel angle via command VP004 Steering wheel angle sensor programming (see
Configuration and programming, section A).
Remove the fault, start the engine and check that the EPAS functions correctly by turning the steering wheel from
lock to lock (parking manoeuvres).
If the fault is still present, contact the Techline.
AFTER REPAIRClear the stored faults.
Check that the EPAS is working.
Deal with any other faults.
