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.
