This fault appears when the computer control section has
overheated.
Check the conformity of fuse: FM13 (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 2 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 1068 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, Electrical
wiring repair, Wiring: Precautions for repair), repair the connector, otherwise replace the wiring.
Check the conformity of the "thermoplunger 2" relay (relay removed):
–Insulation between connections BP91 and 3JAD or 3JD and 3JAC of component 1068 or 1550.
– Measure the resistance between connections 3FB and 3JAA of component 1068 or 1550.
Replace the relay if the resistance is greater than 200 Ω or less than 20 Ω.
Check the absence of interference resistance of the following connection:
•3JAA between components 120 and 1068 or 1550.
Also check the insulation on the following connections:
Check the + 12 V after relay supply to the thermoplunger 2 relay mounting on the following connection:
•3FB of component 1068
or 1550.
Check the + 12 V after fuse battery supply to the thermoplunger 2 relay mounting on the following connection:
•BP91 of component 1068 or 1550.
If the connection or connections are 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.
