AFTER REPAIRDeal with any other faults. Clear the fault memory.
Switch off the ignition until the end of the power-latch phase, and carry out a road test
followed by a check with the diagnostic tool.

Check the continuity of the following connection:
•3JAB between components 120 and 1069 or 1550.
Check the + 12 V after relay supply to the thermoplunger 3 relay mounting on the following connection:
•3FB of component 1069 or 1550.
If the connection or connections are faulty and if there is a repair method (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the wiring, otherwise replace the wiring.

NOTESNone.
Check the conformity of fuse: FM13 (70A) or FM14 (70A) or FM3 (30A) (see MR364 (Mégane II ph2), MR370
(Scénic II ph2), MR 395 (Laguna II ph2), 402 (Vel Satis ph2), 405 (Espace IV ph2) Mechanical, 81C, Fuses,
Fuses: List and location of components).
Check the condition of the thermoplunger 3 relay mounting connector on the engine fuse box or additional heater
interface unit (see Wiring Diagram Technical Note, Laguna II ph2, Vel Satis ph2, Espace IV ph2, Mégane II
ph2, Scénic II ph2, component code 1069 or 1550).
Check the condition of the engine management computer connector (see Wiring Diagram Technical Note,
Laguna II ph2, Vel Satis ph2, Espace IV ph2, Mégane II ph2, Scénic II ph2, component code 120).
If the connector or connectors are faulty and if there is a repair procedure (see Technical Note 6015A, Repairing
electrical wiring, Wiring: Precautions for repair), repair the connector, otherwise replace the wiring.
Check the conformity of the thermoplunger 3 relay (relay removed):
–Insulation between components BP9 and 3JAC or 3JC of component 1069 or 1550.
– Measure the resistance between connections 3FB and 3JAB of component 1069 or 1550.
Replace the relay if the resistance is greater than 1 kΩ or less than 6 Ω.
Replace the unit if the resistance is less than 1 kΩ (M9R721).
Check the insulation in relation to +12 V of the following connection:
•3JAB between components 120 and 1069 or 1550.
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.
