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.

PR108COMPUTER SUPPLY VOLTAGE
NOTESThere must be no present or stored faults.
No electrical consumers.
Ignition onIf voltage < Min., the battery is discharged::
– check the charging circuit to detect the origin of this fault (see Technical Note
6014A, Checking the charging circuit).
If voltage >Max., the battery may be over-charged::
– Check that the charging voltage is correct with and without electrical consumers
(seeTechnical Note 6014A, Checking the charging circuit).
Idling
If # < Minimum, the charging voltage is too low::
– check the charging circuit to detect the origin of this fault (see Technical Note
6014A, Checking the charging circuit).
If # > Maximum, the charging voltage is too high:
– the alternator regulator is faulty.
Repair this fault and check the electrolyte level in the battery.
If the battery and
charge circuit are
correctDeal with the fault by applying the interpretation of fault DF002 Computer.

NOTESOnly consult this customer complaint after a full check with the diagnostic tool.
Special note:
Use the Wiring Diagrams Technical Note for Thalia 2/Symbol 2 and Kangoo VLL.
Check the condition of the connection of the alternator signal connector, on the vehicle alternator, component code
103.
If the connector is faulty and there is a repair procedure (see Technical Note 6015A, Electrical wiring repair,
Wiring: Precautions for repair), repair the connector, otherwise replace the wiring.
Check the charging circuit if necessary (see Technical Note 6014A, Checking the charging circuit).
Check that the battery charge warning light illuminates on the instrument panel during + after ignition with the
vehicle engine stopped.
Check the insulation, continuity and absence of interference resistance on the following connection:
●2A between components 186 and 103.
If the connection is faulty and there is a repair procedure (see Technical Note 6015A, Electrical wiring repair,
Wiring: Precautions for repair), repair the wiring, otherwise replace it.
If the fault is still present, contact the techline.
