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.

NOTESThis fault may occur if the engine operating status multiplex signal is defective.
Check the vehicle's battery voltage.
Repair if necessary.
Test the multiplex network.
Check the integrity of the multiplex network (see 88B, Multiplexing).
Deal with any faults.
Check the conformity of ET023 and PR003.
Run fault finding on the injection and ABS.
Repair if necessary.
If the fault is still present, contact the Techline.
