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.
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.
