2.DEF : Multiplex line connection fault
NOTESConditions for applying the fault finding procedure to a stored fault:
The fault is declared present during a road test.
Special notes:
Use bornier Ele. 1681 or Ele. 1590 for any operation on the injection computer
connectors.
Check the ABS computer connections.
Check the injection computer connections.
Repair if necessary.
Run fault finding on the multiplex network, (see 88C, Airbags - seat belt pretensioners) and the ABS, (see 38C,
Anti-lock braking system).
If the fault is still present, contact the Techline.
AFTER REPAIRDeal with any faults.
Carry out a road test followed by another check with the diagnostic tool.

Check the operation of the EGR valve:
–exit fault finding mode in CLIP,
–switch off the vehicle ignition,
–disconnect the EGR valve connector,
–remove the EGR valve.
–Check that there are no particles blocking the movement of the piston.
–Clean the EGR valve, (see Technical Note 3916A Cleaning the EGR valve).
–Refit the EGR valve, run command SC036 Reinitialise programming and select EGR valve to reinitialise the
EGR valve offsets (see Replacement of components).
If the valve is jammed or irrevocably seized, replace the EGR valve. Run command SC036 Reinitialise
programming and select EGR valve to reinitialise the EGR valve offsets (see Replacement of components).
