System outline
The electric power-assisted steering system uses a pump assembly which generates the hydraulic pressure
assistance in the steering circuit. The electric motor turns at a constant speed and the system supplies a constant
level of power-assisted steering.
Operation of the electric power-assisted steering system is managed by a computer integrated into the pump
assembly.
Correct system operation is checked using sensors integrated into the pump assembly of the power-assisted
steering.
The power-assisted steering is only available when the ignition is on and the vehicle engine is running (the presence
of the alternator signal is interpreted by the computer as "engine running").
Functions provided
●Main function
Power-assisted steering: the system supplies a constant level of power-assisted steering. The electric motor of the
pump assembly in the power-assisted steering runs at a constant speed.
●Temperature Protection Function
The temperature of the pump assembly is monitored by two sensors, one for the oil temperature, the other for the
temperature of the internal electronics.
There are two possible cases:
●When the maximum of the two temperatures exceeds the high temperature threshold (107°C), the rotation
speed of the electric motor decreases from 2650 rpm to 800 rpm in increments of 40 rpm each second,
for as long as the temperature exceeds the threshold of 107°C,
●When the maximum of the two temperatures exceeds the overheating temperature threshold (125°C), the
pump assembly switches off and no steering assistance is provided for as long as it takes for the
temperature to return below this threshold.
●Fault finding function
The pump assembly computer includes a self-test procedure function. The required information can be accessed
using the diagnostic tool, by the HK line.

SETTINGS
VP001: Write VIN.
This command permits manual entry of the vehicle's VIN into the computer.
Use this command each time the pump assembly of the power-assisted steering is replaced.
Check that the configuration is correct by reading the identification ID010 V.I.N. code.
VP005: Enter After-Sales operation date.
This command allows is used to manual enter the date of the last After-Sales operation on the pump
assembly system of the power-assisted steering.
Use this command after every operation, whether mechanical or electric/electronic, on the pump
assembly of the power-assisted steering.
Consecutively enter the six figures of the date: two for the year, two for the month and two for the
day. E.g. 000706 (06 July 2000).
Check that the configuration is correct by reading the identification ID018 Read last After-Sales
operation date.
