COMPUTER REPLACEMENT OR REPROGRAMMING PROCEDURE
The system can be programmed and reprogrammed via the diagnostic socket using the RENAULT CLIP diagnostic
tool (see Technical Note 3585A or follow the instructions provided by the diagnostic tool).
After reprogramming or replacing the computer:
–Switch the ignition off and then on again.
–Start and run the engine in LPG mode then stop the engine (to initialise the computer) and wait for
30 seconds.
–Switch on the ignition and use the diagnostic tool to carry out the following steps:
–use command VP001 Write VIN,
–after the injection has been reprogrammed, stored faults may appear on other computers. Clear the memories of
these computers,
–carry out a road test followed by another check with the diagnostic tool. IMPORTANT
–switch on the diagnostic tool (mains or cigarette lighter supply),
–connect a battery charger,
–shut down all the electrical consumers (lights, interior lights, air conditioning, radio CD, etc.),
–wait for the engine to cool down (coolant temperature below 60 °C and air temperature below 50 °C).

NOTESFault finding procedure application conditions:
Only when fault is present.
Special note:
This fault appears when the ignition is switched off (power latch phase: computer data
backup phase) or during the engine stop phase.
Clear the faults from memory and then start the engine.
If the fault is still present, contact the Techline.
AFTER REPAIRDeal with any faults displayed by the diagnostic tool.
Clear the computer memory.
Carry out a road test followed by another check with the diagnostic tool.

LPG TO PETROL TRANSITION
YES
NO
NOTESThere must be no present or stored faults.
Ignition on, engine stopped.
Status ET095 indicates YES for a variable period during the transition from LPG to petrol mode.
Check that the fuel pump starts when petrol mode is entered.
Check that status ET025 Fuel pump becomes ACTIVE.
If the fuel pump does not start, check:
–the fuel pump cut-off relay (see DF024 Fuel pump cut-off relay circuit),
–the petrol computer (see 17B, Petrol injection).
Repair or replace the faulty components, if necessary.
If the status is still not correct, contact the Techline.
AFTER REPAIRFollow the instructions to confirm repair.

IMPORTANT
For any operation on a component of the LPG supply circuit, consult the safety instructions (see 17D,
LPG injection, Introduction, Safety instructions for all operations).
NOTESThere must be no present or stored faults.
Ignition on, engine stopped.
Special note
The duration of the transition varies according to the outside temperature.
Status ET095 indicates YES for a variable period during the transition from LPG to petrol mode.
Check that the fuel pump starts when petrol mode is entered.
Check that status ET025 Fuel pump becomes ACTIVE.
If the fuel pump does not start, check:
–the fuel pump cut-off relay (see DF024 Fuel pump cut-off relay circuit),
–the petrol computer (see 17B, Petrol injection).
Repair or replace the faulty components, if necessary.
If the status is still not correct, contact the Techline.
AFTER REPAIRFollow the instructions to confirm the repair:

AC005
FUEL TANK SENDER RELAY
NOTESWith ignition on and engine stopped.
Switch on the ignition and run command AC005.
If the fuel sender relay does not click 10 times, carry out the fault finding procedure below.
Check the insulation, continuity and the absence of interference resistance on the connection between:
For Mégane 2:
LPG computer track E4
Fuel sender relay track B2
For Logan:
LPG computer track E4
Double relay control unit track B2Earth
Earth
Repair if necessary.
Check the insulation, continuity and the absence of interference resistance on the connection between:
For Mégane 2:
Fuel sender relay track B3
For Logan:
Double relay control unit track B3track B5 of the fuel sender relay
track B5 of the fuel pump relay
Repair if necessary.
If the fault is still present, replace the fuel sender relay (see MR 364 Mechanics, 17D, LPG injection).
AFTER REPAIRRepeat the conformity check from the start.
