NOTESSpecial notes:
Only perform the tests if the statuses do not correspond with the system programming
functions.
Note:
Statuses ET704 and ET705 should change status at the same time. If they are inconsistent, consult the
interpretation of fault DF228 Brake signal.
ACTIVE
or
INACTIVEIf the brake lights are working, check the continuity and the absence of interference
resistance between the following connections:
Brake light switch, track 3 Injection computer, connector A,
black, 32-track track E4
If there is a repair method (see Technical Note 6015A, Repairing electrical wiring,
Wiring: Repair precautions), repair the wiring, otherwise replace it.
If the brake lights are not operational, check:
– the condition and fitting of the brake switch,
– the condition and conformity of the brake light fuse,
– the conformity of the values in the following table:
Continuity between
tracksInsulation between
tracks
Switch pressed
(Brake pedal released)3 and 4 1 and 2
Switch released
(brake pedal pressed)1 and 2 3 and 4
Replace the switch if the values obtained are not correct.
AFTER REPAIRDeal with any other faults. Clear the fault memory.
Switch off the ignition and carry out a road test followed by a test with the diagnostic
tool.

IF THE PUMP DOES
NOT OPERATEDisconnect the fuel pump.
Check the cleanliness and condition of the connections.
Check for the + 12 V feed on the fuel pump connector with the ignition on (see
Technical Note 8227 Wiring Diagram, MEGANE II, 456).
If there is no + 12V:
– disconnect the battery,
– disconnect the connector marked PPH2 in the Protection and Switching Unit,
– check the cleanliness and condition of the connections,
– using the Universal bornier, check for continuity on the following connection:
Protection and Switching Unit
connector PPH2 track 5Fuel pump connector
Repair if necessary.
Reconnect the Protection and Switching Unit connector and reconnect the battery.
If the + 12 V feed is still not present on the fuel pump relay connector with the ignition
on, there is a fault with the Protection and Switching Unit.
Contact the Techline.
Check that the earth on the fuel pump connector is present with the ignition on
(seeTechnical Note 8227 Wiring Diagram, MEGANE II, 456).
Repair if necessary.
If the fault is still present, replace the fuel pump.
