CC.0 : Short circuit to earth
CC.1 : Short circuit to + 12 V
CO : Open circuit
NOTESConditions for applying the fault finding procedure to a stored fault:
The fault becomes present after starting the engine.
If the fault is present:
CC.0: The water heater interface unit is permanently actuated.
CC.1: The water heater interface unit is not actuated.
The level 1 fault warning light is lit on the instrument panel.
Use CLIO III, MODUS, MEGANE II ph2, SCENIC II ph2 and Kangoo II Wiring
diagrams Technical Note.
Check the connection and condition of the thermoplunger unit connector, component code 1550 (see MR 392,
385, 364, 370 and 417, Mechanical, 61A, Heating system, Heating system: List and location of
components).
If the connector is faulty and there is a repair procedure (see Technical Note 6015A, Electrical wiring repair,
Wiring: Precautions for repair), repair the connector, otherwise replace the wiring.
Check the connection and condition of the injection computer connector, component code 120 (see MR 392,
385, 364, 370 and 417, Mechanical, 13B, Diesel injection, Diesel injection computer: Removal - Refitting).
If the connector is faulty and there is a repair procedure (see Technical Note 6015A, Electrical wiring repair,
Wiring: Precautions for repair), repair the connector, otherwise replace the wiring.
With the ignition on, check for + 12 V on connections BP35 and BP36 of the thermoplunger unit, component
code 1550.
If the connection(s) are faulty and there is a repair method (see Technical Note 6015A, Repairing electrical
wiring, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
Check the continuity, insulation and the absence of interference resistance on the following connection:
–3JAA between components 1550 and 120.
If the connection is faulty and there is a repair procedure (see Technical Note 6015A, Electrical wiring repair,
Wiring: Precautions for repair), repair the wiring, otherwise replace it.
If the fault is still present, contact the Techline.
AFTER REPAIRDeal with any faults displayed by the diagnostic tool.
Clear the computer fault memory.
Carry out a road test followed by another check with the diagnostic tool.

– Refit the return pipes.
– Refer to parameters PR008 Rail pressure
setpoint and PR038 Rail pressure.
–Does PR038 Rail pressure follow PR008 Rail
pressure setpoint during the 3second
starting action phase?
NO
Remove the heater plugs and check for
moisture.
If the heater plugs are wet with fuel, it is possible
that the injector is leaking.
Are the heater plugs wet with fuel?
NO
Replace the pump (see replacement of
components).
