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.

CRUISE CONTROL/SPEED LIMITER BUTTONS
NOTESSpecial notes:
Only perform the tests if the statuses do not correspond with the system programming
functions.
INACTIVEStatus ET703 becomes "INACTIVE" when none of the cruise control/speed limiter
buttons is pressed. These buttons are located on the steering wheel.
If status ET703 does not display "INACTIVE",
●check the condition of the cruise control/speed limiter +/- button and the condition of
its connector,
●check the condition of the cruise control/speed limiter R/0 button and the condition of
its connector.
INCREASEStatus ET703 becomes PLUS when the cruise control/speed limiter + button is pressed.
This button is on the steering wheel, on the left-hand side.
If status ET703 does not display PLUS, check the condition of the cruise control/speed
limiter +/- button, and the condition of its connector. Repair if necessary.
To carry out these checks and measurements in complete safety, observe the
recommendations for removing the driver's front airbag (see MR 364 Mechanical, 88C,
Airbag and seat belt pretensioners, Driver's front airbag, Removal - Refitting)
Measure the resistance on the following connection with the "+" button pressed:
Injection computer,
connector A, black, 32-track track D2 "+/-" button track 2.
connector A, black, 32-track track D3 "+/-" button track 1.
If the resistance is not approximately 300 Ω, check the continuity of the connection when
the button is not pressed.
If there is continuity, replace the +/- control button.
If there is a repair procedure (see Technical Note 6015A, Repairing electrical wiring,
Wiring: Precautions for repair), repair the wiring, otherwise replace it.
AFTER REPAIRDeal with any other faults. Clear the fault memory.
