PASSENGER AIRBAG LOCKING CHANGE OF STATE
NOTESSpecial features: the vehicle user has 10 seconds after switching on + after ignition
feed to inhibit the passenger airbag with the switch. After this time, the computer will
store this fault and light up the warning light on the instrument panel. Switching the
ignition off and on erases this fault from the computer memory.
Set the locking switch to the desired position, switch the ignition off and wait for a few seconds.
Switch the ignition back on and check that the fault is gone.
AFTER REPAIRClear the computer memory then switch off the ignition.
Carry out the check again using the diagnostic tool and, if there are no faults, unlock
the computer.
