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.

Precautions for use
●The power-assisted steering pump assembly (the computer, the electric motor, the hydraulic pump, the oil
reservoir) cannot be separated.
OPERATIONS FOR REPLACING THE PUMP ASSEMBLY
Before replacing the power-assisted steering pump assembly, perform fault finding on the system and apply the
appropriate fault finding procedure.
The power-assisted steering pump assembly may only be replaced after approval from Techline.
After replacing the pump assembly, calibrate the computer using the diagnostic tool.
When replacing the power-assisted steering pump assembly, perform the following operations:
●disconnect the vehicle battery,
●replace the power-assisted steering pump assembly (see MR 423 Mechanical, 36B, Power-assisted steering,
Power-assisted steering pump assembly: Removal - Refitting),
●reconnect the vehicle battery,
●connect the diagnostic tool, switch on the ignition and establish dialogue with the computer of the power-assisted
steering pump assembly,
●Enter the vehicle VIN using command VP001 Enter VIN (see Programming),
●write the date of the last After-Sales operation using command VP005 Enter After-Sales operation date (see
Programming),
●switch off the ignition for at least 15 seconds for the configurations to register, without disconnecting the battery,
●switch on the ignition and establish dialogue with the computer of the power-assisted steering pump assembly,
●check that there are no faults and that the parameters are correct,
●start the vehicle engine and check that the power-assisted steering pump assembly is operating correctly (power-
assisted steering available with the engine running),
●check that there are no faults and that the parameters are correct. WARNING:
To prevent any accidents, it is essential to disconnect the battery when performing operations on the front axle,
regardless of the operation, to remove the risk of trapping someone between a wheel and the body if the power-
assisted steering is accidentally triggered due to a fault in the pump assembly system.

NOTESOnly consult this customer complaint after a full check with the diagnostic tool.
Check the pressure and condition of the tyres, the condition of the joints and the front axle geometry.
Check the vehicle battery voltage, component code 107.
Check the charging circuit if necessary (see Technical Note 6014A, Checking the charging circuit).
Do not operate the power-assisted steering pump assembly for at least 1 hour.
Check that parameters PR008 Computer temperature and PR016 Oil temperature are correct (see Conformity
check).
Check that no component placed in the area around the power-assisted steering pump assembly causes an
abnormal rise in the temperature of the pump assembly.
If the fault is still present, contact the techline.
