DEF: Sensor internal electronic fault
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, then returning it to the centre.
Notes:
This fault causes:
Loss or absence of steering assistance with STOP warning light + Message
lighting up.
–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.
If, in the fault occurrence context (computer operating values frozen when fault
occurs) PR108 Computer supply voltage is less than 10 V, check the battery
voltage, the tightness and the condition of the battery terminals and check the
charging circuit.
Procedure to apply for internal fault codes 1 and 69 of PR143.
Contact Techline.
Procedure to apply for internal fault codes 48, 66, 64, 65 and 67 of PR143.
Check the condition of the 3 white EPAS connectors and check that they are locked correctly.
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, then returning it to the centre.
Notes:
This fault leads to degraded assistance with no warning light or message or an
assistance that is limited to 10% with the SERVICE indicator light + Message.
–Risk of ESP fault.
–The computer records an occurrence context (computer operating values frozen
when fault occurs). To view this information, click on the fault description (camera

finding procedure to apply.
Procedure to apply for internal fault codes 83 and 85 of PR143.
Only for Vdiag 05 and 09:
Check status ET020 Steering wheel angle programming which should be STATUS 4; if not, program the
steering wheel angle sensor VP004 Steering wheel angle programming (see Configuration and
programming).
If the fault is still present after the ignition has been switched on several times, contact the Techline.
Procedure to apply for internal fault codes 84 and 86 of PR143.
Contact Techline.
AFTER REPAIRClear the stored faults.
Check that the EPAS is working.
Deal with any other faults.

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.
