PR003
VEHICLE SPEED
NOTESThis signal is sent by the ABS computer to the multiplex network.
The vehicle speed signal can adapt the steering assistance to the vehicle speed.
PR003 must be equal to the actual vehicle speed, within 6 mph (10 km/h).
If the parameter does not match the actual vehicle speed:
–run fault finding on the multiplex network using the diagnostic tool,
–consult the interpretation of faults DF033 Multiplex network and DF057 Vehicle speed multiplex signal.
If the fault is still present, contact the Techline.
Note:
If the vehicle speed multiplex signal is absent or invalid, the value displayed on the tool is 0 or a fixed value
(depending on the configuration).
AFTER REPAIRCarry out a road test, followed by a check with the diagnostic tool.

PR014
LEVEL OF ASSISTANCE AVAILABLE
The assistance level is the percentage of assistance authorised by the power-assisted steering computer.
This assistance level depends:
–on the status of the vehicle engine (started or stopped),
–on any system faults,
–on the system temperature,
–battery voltage.
Parameter PR014 relates to EPAS motor thermal protection.
Assistance limitation due to an excessively high temperature, can be deactivated by not actuating the steering
system for at least 15 minutes.
Note:
In normal operation, with the engine running and a battery voltage greater than or equal to 10 V, the displayed
value of PR014 should be 100 % and may fall to approximately 15 % if thermal protection is active. It is at 0 % if
the battery voltage is less than or equal to 9 V or 99 % with the engine stopped or stalled.
AFTER REPAIRCarry out a road test, followed by a check with the diagnostic tool.

NOTESNone
Check the vehicle battery voltage and the condition of the system's connections.
Repair if necessary.
Check the steering wheel angle sensor programming (ET020 = STATUS 4)
If the sensor is not calibrated, program the steering wheel angle sensor (procedure VP004 Steering wheel angle
sensor programming).
If the fault is still present, contact the Techline.
AFTER REPAIRCarry out a road test followed by a check with the diagnostic tool.
