Tool
commandDiagnostic tool titleComments
RZ001 Fault memoryThis command is used for clearing the computer's stored
faults.
RZ002 EGR programming adaptivesUse this command when replacing the EGR valve or after it has
been cleaned.
RZ004Pressure regulation
adaptivesUse this command when replacing all four injectors at once. It
enables you to reset the injector adaptive programs.
RZ005 ProgrammingThis command enables you to reinitialise the entire computer
configuration according to the vehicle.
AC001 Preheating unitActivating this actuates the preheating unit to test the heater
plug supply. In the event of a fault, refer to the interpretation
of DF017 Preheating unit control circuit.
AC002 EGR solenoid valveThis command actuates the EGR valve. In the event of a fault,
refer to the interpretation of faults DF016 "EGR control
circuit" and DF114 "EGR solenoid valve circuit".
AC004Turbocharging solenoid
valveThis command actuates the turbocharging solenoid valve. In
the event of a fault, refer to the interpretation of faults
DF261 "Turbocharger actuator circuit" and DF427 "Turbo
actuator control".
AC005 Cylinder 1 injectorThis activation makes it possible to check injector 1 by
listening. In the event of a fault, refer to the interpretation of
fault DF026 Cylinder 1 injector control circuit.
AC006 Cylinder 2 injectorThis activation makes it possible to check injector 2 by
listening. In the event of a fault, refer to the interpretation of
fault DF027 Cylinder 2 injector control circuit.
AC007 Cylinder 3 injectorThis activation makes it possible to check injector 3 by
listening. In the event of a fault, refer to the interpretation of
fault DF028 Cylinder 3 injector control circuit.
AC008 Cylinder 4 injectorThis activation makes it possible to check injector 4 by
listening. In the event of a fault, refer to the interpretation of
fault DF029 Cylinder 4 injector control circuit.
AC010 High pressure pumpActivating this lets you listen to the operation of the high
pressure pump.
AC028 Static testThis activation allows systems to be detected and starts the
diagnostic check of the EGR and high pressure pump circuits
(Ignition switched on, engine stopped).
AC029High pressure circuit sealing
testThis activation allows the high pressure circuit sealing to be
checked after an operation has been carried out
(Engine running vehicle stopped).
