NOTESSpecial notes:
If the pre-postheating unit has a short circuit to earth there is
a risk that the heater plugs will be operated continuously.
The heater plugs and the engine may be damaged.
Check the pre-postheating unit connections and the heating plug supply cables.
Check the injection computer connections.
Repair if necessary.
Check the condition of supply fuse F2 (70A) on the power supply fuse board.
Check the continuity and insulation from earth of the following connections:
– connection code3FY,
– connection code 3FF.
Between components 120 and 257.
If the connection or connections 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.
If the fault is still present, replace the pre-postheating unit.
1.DEF
NOTESNone
Check the pre-postheating unit connections and the heating plug supply cables.

Repair if necessary.
Check the condition of supply fuse F2 (70A) on the power supply fuse board.
Check the continuity and insulation from earth of the following connections:
– connection code3FY,
– connection code 3FF,
Between components 120 and 257.
If the connection or connections are faulty and there is a repair method (see Technical Note 6015A, Repairing

NOTESConditions for applying the fault finding procedure to a stored fault:
The fault is declared present after several attempts to start the engine or after running
actuator command AC001 Preheating unit.
Special notes:
It is difficult or even impossible to start the engine when cold.
If the fault is present, the level 1 warning light is lit.
Use bornier Elé.1681 or Elé.1590 for any operation on the injection computer
connectors.
Check the pre-postheating unit connections.
Check the connections on all of the heater plugs.
Repair if necessary.
Check fuse F2 for Mégane II and Scénic II and FM12 for Laguna II (70A) located on the power supply fuse
board.
Check the resistance of the heater plugs:
Replace any plugs whose resistance is not less than 2 Ω at + 20°C.
Check the continuity and absence of interference resistance of the following connections:
– connection code 37AB between components 257 and 682.
– connection code 37AC between components 257 and 683.
– connection code 37Z between components 257 and 680.
– connection code 37AA between components 257 and 681.
Check for + 12 V on connection BP35 of the preheating unit (via fuse F2 for Mégane II and Scénic II and FM12
for Laguna II (70A).
If the fault is still present.
Check the injection computer connections.
Check the continuity and absence of interference resistance of the following connections:
– connection code3FY,
– connection code 3FF.
Between components 120 and 257.
If the connection or connections 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.
If the fault is still present, replace the pre-postheating unit.

NOTESConditions for applying the fault finding procedure to stored faults:
The fault is declared present after:
– the ignition is switched on,
– with the engine running,
– actuator command AC063 Thermoplunger no. 1 relay.
If faults DF033 “Thermoplunger relay 2 control circuit” and DF034
“Thermoplunger relay 3 control circuit” appear, ignore them and go straight to
configuration CF030 “Thermoplunger configuration”.
Special notes:
Use bornier Elé. 1681 for all operations on the engine management computer
connectors.
check the engine management computer connections.
Check the thermoplunger connections, component code 898.
Repair if necessary.
Check for + 12 V after ignition supply on connections BP27 and BP35 of component 1550.
If there is no + 12 V supply, refer to the interpretation of fault DF015 Main relay control circuit.
Repair if necessary.
Check the continuity and absence of interference resistance of connection 3JA between components 120
and 1550.
If the connection or connections 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.
Using a test light, check the supply by running command AC063 Thermoplunger no. 1 relay on connection 3JB
between components 898 and 1550.
Measure the resistance of the thermoplunger, component code 898.
Replace the thermoplunger, component code 898 if the resistance is greater than 2 Ω.
Replace the water heater interface unit if necessary.
Using a test light, check that the water heater interface unit is properly earthed by running command AC063
Thermoplunger no. 1 relay on connection 3JA between components 120 and 1550.
If the fault is still present, contact the Techline.
AFTER REPAIRDeal with any faults.
Carry out a road test followed by another check with the diagnostic tool.
