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.

ET415
(CONTINUED 1)
STATUS 2Brake pedal depressed
The cruise control function is deactivated when the brake pedal is depressed.
Status ET415 becomes STATUS 2 when driving with cruise control active (ET042
Cruise control/Speed limiter: CRUISE CONTROL) and the brake pedal is depressed.
This deactivates cruise control.
Reinitialise status ET415 on the injection computer by running command RZ001
"Fault memory".
If status ET415 becomes STATUS 2 without depressing the brake pedal, consult the
interpretation of statuses ET704 Brake switch no. 1 and ET705 Brake switch no. 2.
STATUS 3Clutch pedal depressed
Manual gearbox ONLY
The cruise control function is deactivated when the gearbox is not coupled to the engine
(clutch pedal depressed).
Status ET415 becomes STATUS 3 when driving with cruise control active (ET042
Cruise control/speed limiter: CRUISE CONTROL) and the clutch pedal is depressed.
This deactivates cruise control.
Reinitialise status ET415 on the injection computer by running command RZ001
"Fault memory".
If status ET415 becomes STATUS 3 without the clutch pedal being depressed, consult
the interpretation of status ET405 Clutch pedal switch.
If the vehicle is fitted with automatic transmission:
Test the multiplex network: check the configuration of the multiplex network in relation to
the vehicle's technical specification, especially the configuration of the automatic
transmission computer (see 88B, Multiplexing)
STATUS 4Cancel button pressed
The cruise control/speed limiter function is deactivated whenever the suspend button is
pressed.
Status ET415 becomes STATUS 4 while driving when:
- Either the cruise control is active.
- Or the speed limiter is active,
- and the driver presses the 0 button.
This action deactivates the Cruise control/Speed limiter.
Reinitialise status ET415 on the injection computer by running command RZ001
"Fault memory".
If status ET415 becomes STATUS 4 without pressing the 0 button, consult the
interpretation of status ET703 Cruise control/speed limiter buttons and run fault
finding on the R/0 control button located on the right-hand side of the steering wheel.
AFTER REPAIRDeal with any other faults. Clear the fault memory.
Switch off the ignition and carry out a road test followed by a test with the diagnostic
tool
