CONTINUED 1
INACTIVE
When the main switch is in rest position (or neutral), status ET042 is INACTIVE.
If CRUISE CONTROL or SPEED LIMITER appears despite the main switch being in
the rest (or neutral) position, carry out the following operations:
Check the connections of the cruise control/speed limiter main switch.
Check for +12 V after ignition feed on the main switch connector.
• Connection code AP43 of component 1546.
Disconnect the main switch and with it in the rest position, check the insulation
between:
• Connection code AP43 and 3FX of component 1546.
• Connection code AP43 and 3PD of component 1546.
Check the continuity between connections AP43 and 3PD of component 1546 in
the speed limiter position.
– Check the continuity between connections AP43 and 3FX of component
1546in the cruise control position.
If these checks are not in order, replace the switch.
Check the continuity, insulation, and the absence of interference resistance on
the following connections:
• Connection code 3FX,
• Connection code 3PD,
between components 1546 and 120.
Also check the engine management computer connectors.
If there is a repair procedure (see Technical Note 6015A, Repairing electrical
wiring, Wiring: Precautions for repair) repair the wiring, otherwise replace it.

SPEED LIMITER
When the driver presses the main switch in the speed limiter position, status
ET042becomes SPEED LIMITER.
If CRUISE CONTROL or INACTIVE appears although the switch was pressed in
the speed limiter position, carry out the following operations:
Check the connections of the cruise control/speed limiter main switch.
Check for +12 V after ignition feed on the main switch connector.
• Connection code AP43 of component 1546.
Disconnect the main switch and with it in the rest position, check the insulation
between:
• Connection codes AP43 and 3FX of component 1546.
• Connection codes AP43 and 3PD of component 1546.
Check the continuity between connections AP43 and 3PD of component 1546 in
the speed limiter position.
Check the continuity between connections AP43 and 3FX of component 1546 in
the cruise control position.
If these checks show incorrect values, replace the main switch.
Check the continuity, insulation and the absence of interference resistance on
the following connections:
• Connection code 3FX,
• Connection code 3PD,
between components 1546 and 120.
Also check the engine management computer connectors.
If there is a repair procedure (see Technical Note 6015A, Electrical wiring repair,

CLEARING
RZ001: fault memory.
This command is used to clear stored faults from the computer's memory.
RZ002: EGR adaptives.
Run this command only when replacing the EGR valve.
RZ004: Pressure regulation parameters.
Run this command when replacing all 4 injectors at once. It enables you to reset the injector adaptive programs.
RZ005: Programming.
This command lets you reinitialise the entire computer configuration according to the vehicle.
COMMANDS
LPG - FUEL CIRCUIT tab
AC010: High-pressure pump.
This command lets you listen for the operation of the high pressure pump.
AC005 to AC008: Injectors of cylinders 1 to 4.
These commands let you listen for the injector on the selected cylinder.
AC028: Static test.
This command activates fault finding for the EGR and high pressure pump circuits.
AC029: High-pressure circuit seal check.
This command lets you check the high pressure circuit sealing after a procedure has been carried out.
AC212: New pump chamber filling.
Use this command only after replacing the high pressure pump (see High pressure pump replacement in
Replacement of components). This command is used to activate the pump repriming sequence.
IGNITION - PREHEATING tab

IMV = fuel flow actuator
TEST 6 High pressure system check
NOTESSpecial note:
Certain faults make it impossible to carry out this test - deal with these first.
IMPORTANT: It is pointless and dangerous to engage the starter motor for more
than 5 seconds.
Preliminary Checks:
– Check for the presence of fuel
– Check that there is no air in the low pressure circuit. Run TEST 1: Low pressure circuit check.
– Ensure that the correct fuel is being used. Run TEST 13 Diesel fuel conformity check.
It is possible to check the high pressure supply pump capacity by carrying out the following procedure:
–With the ignition off, disconnect the low pressure actuator from the pump (IMV brown connector) and connect
a test IMV or the MOT. 1711 adapter.
– Electrically disconnect the four injectors.
– Switch on the ignition, connect the diagnostic tool and re-establish dialogue with the injection system.
– Go to the Main computer statuses and parameters screen.
– Run the test cold, PR064 Coolant temperature < 30°C or equal to the ambient temperature.
– Engage the starter for 5 seconds.
– Read the rail pressure maximum value (PR038) during the test on the diagnostic tool.
Is the rail pressure greater than 1050 bar?
A
NO
B
YES
