AUTHORISED
INHIBITED
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.

CRUISE CONTROL/SPEED LIMITER DEACTIVATION
NOTESSpecial notes:
Only perform the tests if the statuses do not correspond with the system programming
functions.
Note:
Cruise control can be activated when the vehicle speed exceeds 18 mph (30 km/h).
Status ET415 displays the various reasons for deactivation of the cruise control/speed limiter function, which are
due to driver demand or the exterior environment.
IMPORTANT
Clear the fault memory by running command RZ001 "Fault memory", to reset this status to "NONE".
NONEThis status is present on the diagnostic tool when:
The computer has been reinitialised.
The computer has been reprogrammed
STATUS 1Traction control request
If the vehicle is fitted with a traction control system, the cruise control function is
deactivated every time the ABS computer calls for traction control.
Status ET415 becomes STATUS 1 when driving with the cruise control active (ET042
Cruise control/Speed limiter: CRUISE CONTROL) and traction control is requested.
This deactivates cruise control.
Reinitialise status ET415 on the injection computer by running command RZ001
"Fault memory".
If status ET415 becomes STATUS 1 with no traction control request (see 38C, Anti-lock
Braking System).
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

(CONTINUED 2)
STATUS 5Cruise control or speed limiter monitoring
This status appears when the vehicle brakes or decelerates sharply without the injection
computer receiving a signal indicating that the brake pedal switch has been pressed.
If status ET415 is STATUS 5, refer to the interpretation of:
- status ET042 Cruise control/Speed limiter,
- status ET703 Cruise control/speed limiter buttons,
- status ET704 Brake switch no. 1,
- and status ET705 Brake switch No 2,
to test the cruise control/speed limiter system components and find the defective
component.
In addition, check the operation of the accelerator pedal, and use the diagnostic tool to
check for a fault on it. Deal with them if necessary.
Reinitialise status ET415 on the injection computer by running command RZ001
"Fault memory".
If status ET415 changes to STATUS 5, deal with present faults or those stored in the
injection computer.
If the fault is still present, contact Techline.
STATUS 6Gear lever in neutral (manual gearbox) or the neutral position (automatic gearbox)
Status ET415 becomes STATUS 6, when driving with cruise control active (ET042:
Cruise control/speed limiter: CRUISE CONTROL) and:
- If the driver puts the gear lever in neutral position on a manual gearbox without
declutching or,
- if the gear lever is in neutral on an automatic gearbox.
This deactivates cruise control.
Reinitialise status ET415 on the injection computer by running command RZ001
"Fault memory".
If status ET415 becomes STATUS 6 without shifting the gear lever into neutral on a
manual gearbox without declutching, or into neutral on an automatic transmission, test
the ABS computer and check the configuration of the tyre size stored in the computer.
If the configuration is correct, contact the Techline.
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.

(CONTINUED 3)
STATUS 7Inconsistency between the request and the vehicle speed
Status ET415 becomes STATUS 7 if the computer detects too great a difference
between the speed requested by the driver and the vehicle speed.
STATUS 7 may occur when driving with the cruise control active (ET042 Cruise
control/speed limiter: CRUISE CONTROL) and when there is significant difference.
This inconsistency deactivates cruise control.
Reinitialise status ET415 on the injection computer by running command RZ001
"Fault memory".
If status ET415 changes to STATUS 7 where there is no significant difference in the
levels, contact the Techline.
STATUS 8Automatic transmission in defect mode.
Status ET415 becomes STATUS 8, when driving with cruise control active (ET042:
Cruise control/speed limiter: CRUISE CONTROL) and if the automatic transmission
is in defect mode.
This signal is conveyed on the multiplex line and deactivates the cruise control.
Carry out a multiplex network test, then run fault finding on the automatic transmission
computer.
Deal with any present or stored faults (see 23A, Automatic transmission,
interpretation of faults).
Clear the automatic transmission computer memory by running command RZ001 Fault
memory.
Reinitialise status ET415 on the injection computer by running command RZ001
"Fault memory".
If status 8 continues, contact the Techline.
STATUS 9Vehicle speed monitoring
Status ET415 changes to STATUS 9 if the vehicle speed received by the computer is
invalid or absent.
This signal is conveyed on the multiplex line and deactivates the cruise control.
Carry out a multiplex network test, then run fault finding on the ABS computer.
Deal with present or stored faults (see 38C, Anti-lock braking system, Interpretation
of faults).
Reinitialise status ET415 on the injection computer by running command RZ001
"Fault memory".
If STATUS 9 is still present, contact the Techline.
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.
