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.
