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.

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.

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.

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.
