NOTESNone.
This fault corresponds to an inconsistency between the computer configuration and the vehicle equipment
detected by the computer. The computer detects the presence of an additional component to its configuration or
the computer detects a programmed component which is not fitted to the vehicle.
2.DEF
NOTESIf the fault is still present, check whether the sensor fitted is
compatible with the airbag computer connected to the
vehicle. If not, order the sensor which is specifically for the
airbag fitted.
Replace the driver's side sensor.
AFTER REPAIRClear the computer fault memory. Switch off the ignition.
Carry out the check again using the diagnostic tool and, if there is no fault, unlock the
computer.

NOTESPriorities when dealing with a number of faults:
If DF065 is present with at least one of the faults DF077, DF232, DF081, begin fault
finding by checking the 8-track connector located underneath the seat.

Lock the computer using the diagnostic tool.
Fit the 64-track test adapter Elé. 1717 and measure the resistance between the tracks 9 and 10, with the seat in
the forward position and in the back position.
When the seat is forward, the resistance should be approximately 400Ω (275Ω When the seat is in the back position, the resistance should be approximately 100Ω (65Ω If the resistances are correct, check the connections of the 64-track computer connector.
If the resistance is incorrect, check that the seat position sensor is correctly fitted on the seat runner.
Check the connections of the 8-track seat connector (tracks A1 and A2).
If all the tests are correct, replace the driver's front seat position sensor.
AFTER REPAIRReconnect the computer, the seat position sensor, and the under-seat connector, then
switch on the ignition again. Clear the computer fault memory. Switch off the ignition.
Carry out the check again using the diagnostic tool and, if there is no fault, unlock the
computer.

1.DEF: Configuration
NOTESIf 1.DEF, check and modify the computer configuration.
If CC.0 or CC.1, apply the diagnostic procedure.
Priorities when dealing with a number of faults:
If the fault DF232 is present with at least one of the faults DF065, DF077, DF081,
begin fault finding by checking the 8-track connector underneath the seat.
Special notes:
Use the 64-track adapter Elé. 1717 when working on the computer connector.
Check the condition and correct connection of the 64-track computer connector (locking system, connections,
etc.).
Make sure the driver's seat belt buckle sensor is properly connected and test its connections.
Check the continuity and insulation of the connections between:
Bornier Elé. 1717 terminal 11
Bornier Elé. 1717 terminal 12Track 2 of the seat belt buckle sensor connector
Track 1 buckle sensor connector
If the connections are OK, replace the driver's seat belt buckle sensor.
If a connection is faulty:
Check the connections of the 8-track connector underneath the seat (tracks B3 and B4) and the connector for
the 2-track sensor.
Repair or replace the harness if necessary.
AFTER REPAIRClear the computer fault memory. Switch off the ignition.
Carry out another check using the diagnostic tool.
