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.

ENGINE OPERATION
NOTESSpecial note:
This signal comes from the injection computer and is transmitted to the Electric Power
Assisted Steering computer via the multiplex network.
STOPPED:The engine has not yet been started, or has been stopped normally with the starter
button.
STALLED:The engine has been stopped, but it stopped abnormally, without using the starter button.
This status may appear for a brief moment during a normal engine stop.
RUNNING:The engine is currently in operation.
STARTING:The engine is currently being activated by the starter.
If the status does not correspond to the actual operation of the engine, carry out fault finding on the multiplex
network (see 88B, Multiplexing) and on the injection (see 13B, Diesel injection and 17B, Petrol injection)
using the diagnostic tool.
AFTER REPAIRPerform a test using the diagnostic tool.

COMPUTER CALIBRATION
NOTESNone.
Between config. 1 and config. 5.
Use the diagnostic tool to check that the configuration correctly corresponds to the vehicle criteria.
If the status is config. 0, calibration was not performed.
Calibrate the computer using command SC001 Computer calibration (see configuration and programming).
