1. SCOPE OF THIS DOCUMENT
This document presents the fault finding method applicable to all computers with the following specifications:
2. CONDITIONS FOR APPLICATION OF THE TESTS DEFINED IN THIS FAULT FINDING
The tests defined in this fault finding should only be applied to vehicles not fitted with side airbags but which are
fitted with the 2nd generation of airbag computers.
These new computers can be identified by the heading AC4 Ph 2 on the fault finding tools.
The tests defined in this fault finding must only be carried out if the fault is present on the vehicle at the time the test
is carried out.
Only the computer fault leads to replacement of the computer, whether the fault is present or simply stored.
If the fault is not present but simply stored, applying the checks recommended in the fault finding will not allow the
reason why this fault was stored to be located. In this case only, the wiring and the faulty component connections
should be checked (it is possible to access the wiring concerned in fault finding mode to try to display the change
from stored fault to present fault).

5. FAULT FINDING PROCEDURE (continued)
5.1 Wiring check
Fault finding problems
Disconnecting the connectors and/or manipulating the wiring may temporarily clear the cause of a fault.
Visual inspection
Look for damage under the bonnet and in the passenger compartment.
Carefully check the protectors, insulation, and routing of the wiring, as well as the mountings.
Physical inspection
When manipulating the wiring, either use the diagnostic tool to detect a change in status, from "stored" to
"present", or the multimeter to view the status changes.
Make sure that the connectors are firmly secured.
Apply light pressure to the connectors.
Twist the wiring harness.
Checking earth insulation
This check is carried out by measuring the voltage (multimeter in voltmeter mode) between the suspect connection
and the 12 V or 5V. The correct measured value is 0V.
Checking insulation against + 12 V or + 5 V
This check is carried out by measuring the voltage (multimeter in voltmeter mode) between the suspect connection
and the earth. In the first instance, the earth may be taken on the chassis. The correct measured value is 0V.
Continuity check
A continuity check is carried out by measuring the resistance (multimeter in ohmmeter mode), with the connectors
disconnected at both ends. The expected result is in the range: 0 < X < 2 for each connection. The line must be
fully checked, and the intermediate connections are only included in the method if this saves time during the fault
finding procedure. The continuity check on the multiplex lines must be carried out on both wires. The measured
value should be between: 0 < X < 2 .
Power supply check
This check can be carried out using a test light (21 W or 5 W depending on the maximum permissible load).
