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 a loss of assistance or an absence of steering assistance and also
illuminates the STOP warning light + Message, or assistance is limited to 30% and
the SERVICE indicator light + Message come on.
–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 3, 33, 34, 35, 50, 51, 112, 113, 128, 145 of PR143.
Contact Techline.
Procedure to apply for internal fault codes 4, 5, 100, 114, 115, 129, 130 and 131 of PR143.
Check the condition of the wiring inside the EPAS and make sure that the 3 white EPAS connectors are correctly
locked.
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.

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.

PROGRAMMING THE STEERING WHEEL ANGLE SENSOR
NOTESSpecial note:
–This status is declared correct when it is STATUS 4 (normal mode); in any other
case, apply this fault finding procedure.
–The SERVICE indicator light will come on if the steering wheel angle calibration has
not been carried out.
VARIOUS POSSIBLE STATUS VALUES (with the meaning):
STATUS 1:
–Straight ahead wheel position not programmed.
–Invalid angle value.
PROGRAMMING NOT COMPLETE.STATUS 3:
–Straight ahead wheel position not programmed.
–Invalid angle value.
–Steering wheel out of range ± 120˚ when after ignition
is switched on.
PROGRAMMING COMPLETE, ANGLE TO BE
CONFIRMED.
STATUS 2:
–Straight ahead wheel position not programmed.
–Invalid angle value.
PROGRAMMING NOT COMPLETE.STATUS 4:
–Straight ahead wheel position not programmed.
–Valid angle value.
PROGRAMMING COMPLETE.
STATUS 1 or STATUS 2
If the status is STATUS 1 or STATUS 2, program the steering wheel angle (see Configuration and
programming).
STATUS 3
If the status is STATUS 3, turn the steering wheel from right lock to left lock then slowly return it to slightly beyond
the centre point (PR135 "Column rotation speed" less than 200˚/s). The status should become STATUS 4.
Note:
A present or stored fault can impede STATUS 4 (carry out the necessary operations by referring to the Fault
Finding Manual).
AFTER REPAIRPerform a test using the diagnostic tool.

ALP2 Loss of vehicle assistance without warning
NOTESOnly consult this customer complaint after a complete check with the diagnostic tool.
The vehicle is no longer assisted if the Electric Power Steering fuse is damaged or supply is lost. The steering is
equivalent to manual steering, manoeuvrable when driving even at low speeds, but very difficult to manoeuvre
when stopped.
Since it is no longer being supplied, the EPAS computer is not capable of lighting the warning light, but the
instrument panel lights the STOP warning light + Message 4 seconds after the loss of the feed causing the loss
of assistance.
The driver will only become aware of the fault through noticing the loss of assistance at the steering wheel.
Check the fuses for the electric power-assisted steering:
Power fuse 80A BP81 in the engine fuse box.
5A AP44 + after ignition fuse on the UPC.
Check the condition of the electric power-assisted steering connectors and repair if necessary.
Check that the electrical feeds to the computer are correct:
2-track connector track 2vehicle earth
2-track connector track 1+ battery feed
8-track connector track 8+ after ignition feed
Repair if necessary.
Check the insulation, continuity and the absence of interference resistance on the connections between the electric
power-assisted steering computer and the instrument panel.
8-track connector track 6 track 30 of the instrument panel
8-track connector track 4 track 29 of the instrument panel
Check that the steering column and steering rack are in sound mechanical condition.
Repair if necessary.
Make sure that the front axle components, such as the track rod ends and shock absorber base plates, are in sound
mechanical condition.
Repair if necessary.
If the fault is still present, contact the Techline.
AFTER REPAIRPerform a test using the diagnostic tool.
