Side sensor programming not carried out
DF033
present
None.NOTES
The absence of this fault corresponds to the absence of programming for the side sensors identification
by the air bag computer (this identification enables the computer to check that the side sensors are the
correct ones for the vehicle).
This bargraph is normally illuminated when the computer is new (it is sold without identification).
Carry out the identification programming for the side sensors using the "Side sensor programming"
command on the fault finding tool.
Erase the computer memory then switch off the ignition
Carry out a check again using the fault finding tool

Driver’s side sensor identification
DF037
present
None.NOTES
This fault is normally present when the computer detects an inconsistency between the recognition signal
emitted by the side sensor and the programming which it has received.
Either the side sensor is not adapted to the vehicle, or the computer comes from another vehicle.
If the sensor has been replaced, fit another sensor adapted to the vehicle.
If the computer comes from another vehicle, use the "Side sensor programming" command on the fault
finding tool to change the computer’s programming.
Erase the computer memory then switch off the ignition
Carry out a check using the fault finding tool and, in the absence of a fault,
unlock the computer.
