Fault finding - Replacement of components
REPLACING A SYSTEM COMPONENT
Disconnect the battery before removing and refitting any pyrotechnic component (airbag module,
pretensioner or seat belt retractor).
The computer must always be locked before any operation on a system component.
REPLACING THE AIRBAG COMPUTER
BEFORE REPLACING THE COMPUTER IT IS ESSENTIAL THAT YOU CONTACT THE TECHLINE.
To ensure that the returned computer's fault can be analysed, do not use command RZ001 "FAULT
MEMORY" when DF001 "COMPUTER" is present or stored.
The airbag computers are sold in locked mode to avoid all risk of accidental triggering (all trigger lines are inhibited).
The "locked" mode is indicated when the airbag fault warning light on the instrument panel lights up.
Follow this procedure to replace an airbag computer:
–check that the ignition is switched off,
–replace the computer,
–modify the computer configuration if necessary,
–enter the VIN into the computer with the diagnostic tool using command VP010 "WRITE VIN",
–switch off the ignition,
–carry out a check using the diagnostic tool,
–unlock the computer with command VP007 "UNLOCK COMPUTER", only if there are no faults indicated by the
diagnostic tool and check that the indicator light has gone out.
