REAR SEAT BELT RETRACTORS CIRCUIT
CC : Short circuit
CO : Open circuit
CC.1 : Short circuit to + 12 V
CC.0 : Short circuit to earth
1.DEF : Configuration
NOTESIf 1.DEF, check and adjust the computer configuration.
Special notes: the rear seat belt retractors are serially wired.
Never do measuring on the trigger lines with any tool other than CLIP or XRBAG.
Use the 64-track (Elé. 1717) adapter to work on the computer connector.
CO - CC
NOTESSpecial notes: Correct the trigger line configuration if the
vehicle is not fitted with rear seat-belt retractors.
Lock the computer.
Switch off the ignition and check that the ignition module of the rear seat belt retractor, driver's side is correctly
connected.
Disconnect the ignition module of the retractor and connect a dummy ignition module to the ignition module
connector.
Switch on the ignition and carry out a check using the diagnostic tool.
Replace the rear seat belt retractor, driver's side, if the fault becomes stored (fault no longer declared present).
Switch off the ignition and check that the ignition module of the rear seat belt retractor, passenger's side is
correctly connected.

connector.
Switch on the ignition and carry out a check using the diagnostic tool.
Replace the passenger's side rear seat belt retractor if the fault becomes stored (fault no longer declared
present).
Disconnect the computer and check the connections of the connector (tracks 19, 20, 41 and 42).
Attach 64-track adapter (Elé. 1717).
The CLIP or XRBAG tool absolutely must be used to measure the resistance in adapter cable J.
If the value indicated is incorrect, the wiring between the computer and the driver's side rear seat belt retractor
ignition module (C0/C3) is faulty.
Repair or replace the wiring if necessary.
The CLIP or XRBAG absolutely must be used to measure the resistance in adapter cable E.
