Switch off the ignition and remove the two steering wheel boss mounting bolts.
Check that it is correctly connected.
Disconnect the steering wheel boss and connect a dummy ignition module to the ignition module
connector.
Switch on the ignition and carry out a check using the fault finding tool.
Replace the air bag if the fault has been memorised (fault no longer declared present).
The XRBAG must be used to measure resistance at point C2 of the driver’s air bag circuit.
If the value obtained is not correct, replace the rotary switch under the steering wheel.
Reconnect the rotary switch under the steering wheel, disconnect the computer connector and fit the 50
track B50 adaptor.
The XRBAG must be used to measure resistance on adaptor cable C .
If the value obtained is not correct,
check the connections on the 50 track connector (tracks 10 and 11)
and replace the wiring if necessary.
If there is no evidence of a fault after these checks have been carried out, check on the air bag computer
base for the 7 shunt opening pins for the 50 track connector.
Check the condition of the computer connections
Check the condition of the 50 track connector (locking system).
With the ignition switched off, disconnect then reconnect the rotary switch connector under the steering
