CC : Short circuit
1.DEF : No signal
NOTES Special notes: Use the B54 50 track adapter to work on the computer connector.
CC NOTES None.
Lock the computer using the command on the diagnostic tool.
Check that the passenger's side sensor is connected correctly and check its wiring. Check the condition of the wiring on the computer (tracks 37 and 38).
Check the condition of the 50 track connector (locking system, wiring, etc.). Ensure continuity and insulation of the connections between:
Bornier B54 terminal 37 track 2 sensor connector
Bornier B54 terminal 38 track 1 sensor connector
Also check the insulation between these connections.
1.DEF NOTES None.
DF183 PRESENT
CO : Open circuit
CC.1 : Short circuit to 12 volts CC.0 : Short circuit to earth
1.DEF : Short circuit between ignition lines
NOTES
Processing priority in event of stacked faults:
In the event of 1.DEF short circuit between 2 ignition lines, follow the procedure below and that for the second fault, to localise the short circuit.
Special notes: Never carry out measuring operations on ignition lines using any tool other than CLIP, NXR or XRBAG.
Use the B54 adaptor to work on the computer connector (Cable G).
CO - CC NOTES None.
Lock the computer.
Switch off the ignition and check that the ignition module of the driver's seat buckle pretensioner is correctly connected.
Disconnect the ignition module of the pretensioner and connect a dummy ignition module to the ignition module connector.
Switch on the ignition and carry out a check using the diagnostic tool.
Replace the driver's seat buckle pretensioner if the fault becomes stored (fault no longer declared present). Reconnect the pretensioner.
Disconnect the grey 16 track connector beneath the driver’s seat and check the connections of the connector (track A7 and A8).
Fit the 8 track adaptor to the wiring harness at point C1.
CLIP, NXR or XRBAG must be used for measuring resistance on cable D of the adapter.
If the value obtained is incorrect, the wiring is faulty between the grey 16 track union and the driver’s seat buckle pretensioner (C1/C3). Replace the wiring if necessary.

CC.1 - CC.0 NOTES None.
Lock the computer.
Switch off the ignition and check that the ignition module of the driver's seat buckle pretensioner is correctly connected.
Disconnect the ignition module of the pretensioner and connect a dummy ignition module to the ignition module connector.
Switch on the ignition and carry out a check using the diagnostic tool.
Replace the driver's seat buckle pretensioner if the fault becomes stored (fault no longer declared present). Reconnect the pretensioner.
Disconnect the grey 16 track connector beneath the driver’s seat and check the connections of the connector (track A7 and A8).
Fit the 8 track adaptor to the wiring harness at point C1.
CLIP, NXR or XRBAG must be used for measuring the insulation appropriate to the type of fault on cable D of the adapter.
If the value obtained is incorrect, the wiring is faulty between the grey 16 track union and the driver’s seat buckle pretensioner (C1/C3). Replace the wiring if necessary.
Reconnect the 16 track connector.
Check the wiring again on the grey 16 track intermediate connector (tracks A7 and A8) and on the 50 track connector (tracks 10 and 35).
Fit the B54 50 track adaptor. The CLIP, NXR or XRBAG tools must be used for measuring the insulation suited to the fault type on cable G of the adaptor.
If the fault persists the wiring is faulty between the computer and the grey 16 track intermediate union (C0/C1). Replace the wiring.
