1.DEFNOTESSpecial notes:
This fault appears when the computer control section has
overheated.
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.
Check the absence of interference resistance of the following connection:
•3JAB between components 120 and 1069 or 1550.
Also check the insulation on the following connections:
Check the + 12 V after relay feed to the "thermoplunger 3'' relay mounting on the following connection:
•3FB of component 1069 or
1550.
Check the + 12 V after fuse battery supply to the thermoplunger 3 relay mounting on the following connection:
•BP9 of component 1069 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.

Check the conformity of the steering wheel controls as follows: disconnect connector689 under the centre cover
of the steering wheel (ohmmeter connected on the steering wheel control side). The measurement should read:
•890 Ω < X < 910 Ω when the Resume button is pressed.
(or the one-touch switch R on the right-hand side of the steering wheel)
•0 Ω < X < 0.8 Ω when the Suspend button is pressed.
(or the one-touch switch O on the right-hand side of the steering wheel)
•290 Ω < X < 310 Ω when the Set + button is pressed.
(or the one-touch switch on the left of the steering wheel)
•90 Ω < X < 110 Ω when the Set - button is pressed.
(or the one-touch switch on the left of the steering wheel)
•Infinite resistance in rest position.
– If the values are not correct, replace the controls on the steering wheel.
– If the values are correct, take the same measurements on connections86G and 86M from component120
(steering wheel control connector connected).
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.
If the values are correct, clear the fault, switch off the ignition, wait for the diagnostic tool message (maximum
