Warning light off when ignition on
Lock the computer using the command on the diagnostic tool.
Check the condition of the warning light bulb.
Ensure the continuity of the connection between the warning light and track 7 of the 30-track connector.
Confirm the presence of 12 volts at the warning light.
If the checks carried out did not reveal the presence of a fault, disconnect the computer connector and fit the B40
30-track adapter. Use the CLIP, NXR or XRBAG tools to test the operation of the instrument panel warning light
from the grey cable marked 1 on the adapter.
If it is possible to illuminate the warning light using the tool, replace the airbag computer (refer to the section
"Replacement of components" for this operation).
If it is impossible to operate the warning light, repeat the preceding checks.
Warning light on when ignition on
Lock the computer using the command on the diagnostic tool.
Disconnect the airbag computer and check the base for the 5 pins that open the connector shunts.
Ensure the insulation to earth of the connection between the warning light and track 7 of the 30-track connector.

ALP1 No dialogue with the airbag computer
NOTESUse Wiring Diagrams Technical Note for Kangoo VLL.
Try to establish dialogue with a computer on another vehicle to make sure that the diagnostic tool is not faulty. If
the tool is not the cause of the fault and if the dialogue cannot be established with any other computer of the same
vehicle, it may be that a faulty computer is disrupting diagnostic lines HK and HL.
Use a process of successive disconnections to locate this computer.
Check the battery voltage and carry out the necessary operations to obtain a correct voltage (10.5 volts < battery
voltage < 16 volts).
Check the presence and condition of the airbag computer supply fuse.
Check that the computer connector is connected correctly and check the condition of its connections.
Check that the supply to the computer is correct:
– Disconnect the airbag computer and fit the B40 30-track adapter.
– Check and ensure the presence of + after ignition between the terminals marked earth and + after ignition.
