YES - NOThe RCHs* are actuated by the UCH.
They are high current consumers.
Consequently, their use is
conditional on the available power
all the time (alternator power).
The injection checks the balance of
available mechanical power
according to the engine operating
conditions (torque, power, etc.) to
authorise, limit, or stop their use.
(This information is sent via the
CAN network to the UCH).
Note: When the RCHs* are actuated,
the injection system must respond
to a fast idle speed request from the
UCH.NONE

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

IGNITION - PREHEATING tab
AC001: Preheating unit.
This command actuates the preheating unit to test the heater plug supply.
EMISSION CONTROL - OBD tab
AC002: EGR solenoid valve.
This command lets you listen to the mechanical operation of the EGR valve.
AC028: Static test.
This command activates fault finding for the EGR and high pressure pump circuits.
TURBO - INLET AIR CIRCUIT tab
AC004: Turbocharging solenoid valve.
This command lets you listen for the operation of the turbocharging solenoid valve.

NOTESOnly consult this customer complaint after a complete check with the diagnostic tool.
Check that the fuel tank is correctly filled and that the fuel is correct: run TEST 13 Diesel fuel conformity check.
Check the levels of engine oil and coolant.
Check the air inlet circuit by running TEST 5 Inlet circuit check.
Is the catalytic converter clogged or damaged?Replace the catalytic converter (see MR
364 (Mégane II) or MR 370 (Scénic II),
Mechanical, 19B, Exhaust, Catalytic
converter: Removal - Refitting).
Check the air inlet circuit by running TEST 2 Electrical circuit check.
Check the electrical conformity of the heater plugs (the resistance value of the heater plug must be less than 2 Ω).
Is the timing set correctly? Carry out the necessary repairs.
Visually check the condition of the engine wiring harness.
