ET022
WAITING FOR LPG CONDITIONS
YES
NO
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.
Status ET022 indicates YES for a variable period during which the computer checks that the LPG system is
operating correctly.
Variable duration depending on:
–ET100 LPG system ready,
–PR002 Coolant temperature,
–PR103 Air temperature,
–PR113 LPG temperature.
Apply the interpretation of faults DF103 LPG expansion valve solenoid valve circuit and DF007 Main relay
circuit.
Manipulate the wiring harness between the LPG computer and the petrol computer until a change in status is
noted.
Check the insulation, continuity and the absence of interference resistance on the connections between:
For Mégane 2:
LPG computer track A1
LPG computer track A2
For Logan:
LPG computer track A1
LPG computer track A2track K3, connector B, petrol computer
track K4, connector B, petrol computer
track 25 of the fuel computer
track 26 of the fuel computer
Repair if necessary.
If the status is still not correct, contact the Techline.

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.
