NOTESConditions for applying the fault finding procedure to stored faults
The fault is declared present when the ignition is switched on or with the engine
running.
Special notes:
If the fault is present, the level 1 warning light will be lit.
IMPORTANT
The fault can appear after the alternator has been saturated for too long.
For stored faults, clear the fault, switch off the ignition and wait for 1 minute, then
perform a road test to confirm the fault before any carrying out any operation.
Run a multiplex network test (see 88B, Multiplexing).
For Laguna II:
If the fault is still present, check the insulation and continuity of connection 2K between components 120 and 103.
If the connection or connections are faulty and there is a repair method (see Technical Note 6015A, Repairing
electrical wiring, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
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.

Repair if necessary.
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).
