CC.0: Short circuit to earth
CC.1: Short circuit to + 12 volts
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.
