ALP1 No dialogue with the computer
NOTESNone
Check the vehicle's battery voltage.
Repair if necessary.
Try the diagnostic tool on another computer on the same vehicle, or on a different vehicle.
Check the condition of the 5A fuse on the UPC (shared between Electric power-assisted steering and Airbag) and
attempt to run fault finding on the system.
If the condition of the fuse is not the cause, carry out the following operations:
–activate forced + after ignition feed or have the engine running,
–disconnect the Electric Power Assisted Steering power connector,
–check the connection by pushing and pulling the connector,
–try running fault finding again using the tool,
–if dialogue can be established the fault is repaired,
–if the fault is still present, apply the following procedure.
Check the electric power-assisted steering and engine compartment fuses (70A) and the passenger compartment
fuse (5A).
Check the continuity and absence of interference resistance on the wiring harness between the battery and
the variable power assisted steering computer:
Black 2-track connector track 1 + Battery
Black 2-track connector track 2 Battery 0 V
Black 8-track connector track 8 + After ignition
If there is a repair procedure (see Technical Note 6015A, Repairing electrical wiring, Wiring: Precautions for
repair), repair the wiring, otherwise change the wiring.
Run fault finding on the multiplex network.
If the fault is still present, contact the Techline.
AFTER REPAIRCarry out a road test followed by a check with the diagnostic tool.

ALP2 Loss of vehicle assistance without warning
NOTES–apply the ALP after a complete check with the diagnostic tool,
–check the conformity of ET026 Computer calibration.
The vehicle loses the assistance function if the electric power assisted steering fuse is broken or the power supply
is lost.
The driver will feel the loss of the assistance on the steering wheel. Steering will then be the same as for unassisted
steering, manoeuvrable when driving even at low speed, but very difficult to manoeuvre when stationary.
Without its power supply, the power-assisted steering computer can no longer illuminate the warning light, and so
the driver is not made aware of the fault.
Check the electric power-assisted steering and engine compartment fuses (70A) and the passenger compartment
fuse (5A).
Change the fuses if necessary.
Check the computer supply voltage:
Black 2-track connector track 1 Vehicle earth
Black 8-track connector track 8 Vehicle earth
If there is a repair procedure (see Technical Note 6015A, Repairing electrical wiring, Wiring: Precautions for
repair), repair the wiring, otherwise change the wiring.
Run a multiplex network test, and interpret any faults.
Check that the steering column and steering rack are in sound mechanical condition.
Repair if necessary.
Check that the front axle components, such as the track rod ends and shock absorber base plates, are in sound
mechanical condition.
Repair if necessary.
If the fault is still present, contact the Techline.
AFTER REPAIRCarry out a road test followed by a check with the diagnostic tool.

ALP3 Poor vehicle handling
NOTESNone
Check using status ET026 Computer calibration that the computer configuration corresponds to the vehicle
equipment, wheel size, vehicle type and engine:
Configure the computer correctly using the diagnostic tool, if necessary (see SC001 Computer calibration).
Check the conformity of PR014 Assistance level available.
Check the condition and pressure of the tyres, the condition of the joints and the front axle geometry.
Check the vehicle battery voltage and the condition of the battery terminals.
Repair if necessary.
Check the condition and presence of the electric power steering supply fuse.
Repair if necessary.
Check the condition of the electric power steering black 2-track power connector.
If there is a repair procedure (see Technical Note 6015A, Repairing electrical wiring, Wiring: Precautions for
repair), repair the connector, otherwise change the wiring.
If the fault is still present, contact the Techline.
AFTER REPAIRCarry out a road test followed by a check with the diagnostic tool.
