IMPORTANT
Before working on an LPG supply circuit component, always refer to the appropriate section of the
Workshop Repair Manual (see17C, LPG Injection, Introduction, Safety advice for all operations).
NOTESThere must be no present or stored faults.
Ignition on, engine stopped.
Check:
– the LPG tank solenoid valve (see DF013 Tank solenoid valve circuit),
– the general relay (see DF007 Main relay circuit),
– the LPG expansion valve solenoid valve (see DF103 LPG expansion valve solenoid valve),
– the LPG pressure sensor (see DF092 Expansion valve downstream pressure sensor circuit),
– the LPG pressure in the tank (see DF031 LPG pressure downstream of expansion valve).
These faults are detected by the LPG injection computer.
Repair or replace the faulty components, if necessary.
Check:
– the LPG filling hoses,
– the supply hoses upstream of the expansion valve,
– the expansion valve,
– the hoses downstream of the expansion valve.
Repair or replace the faulty components, if necessary.
If the status is still not correct, contact the Techline.
AFTER REPAIRRepeat the conformity check from the start.

IMPORTANT
Before working on an LPG supply circuit component, always refer to the appropriate section of the
Workshop Repair Manual (see17C, LPG Injection, Introduction, Safety advice for all operations).
NOTESThere must be no present or stored faults.
Ignition on, engine stopped.
Special Note
Check that there is LPG in the tank.
Check that there is no fault on the petrol injection computer.
Test the LPG injection computer (see17C, LPG injection).
Using parameters PR001 Manifold pressure and PR112 LPG pressure downstream of the expansion valve,
check that PR112 - PR001 = 800 mbar.
If PR112 - PR001 < 800 mbar, check:
– the LPG tank solenoid valve (see DF013 Tank solenoid valve circuit),
– the expansion valve,
– the LPG pressure downstream of the expansion valve (see PR112 LPG pressure downstream of expansion
valve).
This fault is detected by the LPG injection computer.
Repair or replace the faulty components, if necessary.
If the status is still not correct, check:
– that the injectors are functioning correctly, using commands AC018 Cylinder 4 injector, AC019 Cylinder 3
injector, AC020 Cylinder 2 injector and AC021 Cylinder 1 injector.
– the condition of the hoses between the expansion valve and the injectors.
Repair the faulty components if necessary.
If the status is still not correct, contact the Techline.
AFTER REPAIRRepeat the conformity check from the start.

TRANSITION FROM PETROL MODE TO LPG MODE
IN PROGRESS
COMPLETE
IMPORTANT
Before working on an LPG supply circuit component, always refer to the appropriate section of the
Workshop Repair Manual (see17C, LPG Injection, Introduction, Safety advice 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.
Check that the LPG tank solenoid valve clicks when LPG mode is entered.
If the LPG tank solenoid valve does not click, check:
– the LPG 10A fuse F15,
– the general relay (see DF007 Main relay circuit),
– the LPG tank solenoid valve wiring (see DF013 Solenoid valve tank circuit).
These faults are detected by the LPG injection computer.
Repair or replace the faulty components, if necessary.
If the status is still not correct, contact the Techline.
AFTER REPAIRRepeat the conformity check from the start.

TRANSITION FROM LPG MODE TO PETROL MODE
IN PROGRESS
COMPLETE
NOTESThere must be no present or stored faults.
Ignition on, engine stopped.
Check that the fuel pump starts when petrol mode is entered.
Check status ET025 Fuel pump changes to 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 (see17B, Petrol injection).
This fault is detected by the LPG injection computer.
Repair or replace the faulty components, if necessary.
If the status is still not correct, contact the Techline.
AFTER REPAIRRepeat the conformity check from the start.

IMPORTANT
Before working on an LPG supply circuit component, always refer to the appropriate section of the
Workshop Repair Manual (see17C, LPG Injection, Introduction, Safety advice for all operations).
NOTESThere must be no present or stored faults.
Ignition on, engine stopped.
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 and DF007 Main relay circuit.
These faults are detected by the LPG injection computer.
Manipulate the wiring harness between the LPG computer and the petrol computer until a change in status is
noted.
Check the insulation, continuity and ensure the absence of interference resistance on the connections
between:
Petrol computer connectorB, track K3 track A1 of the LPG computer
Petrol computer connectorB, track K4 track A2 of the LPG computer
Repair if necessary.
If the status is still not correct, contact the Techline.
AFTER REPAIRRepeat the conformity check from the start.
