If the ignition is not switched on, status ET001 should be ABSENT.
As soon as the ignition is switched on, the computer should be supplied with power. Status ET001 becomes
PRESENT.
If this status remains locked on ABSENT, follow the procedure below:
– Check the condition of fuse FM3 (30A) in the engine fuse and relay box (see MR 395 (Laguna II ph2), 405
(Espace IV ph2) Mechanical, 81C, Fuses, Fuses: List and location of components).

MR370 (Scénic II ph2) Mechanical, 81C, Fuses, Fuses: List and location of components).
Check the continuity and absence of interference resistance on the following connection:
•3AA between components 120 and 983 or 1337.
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.
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 is faulty and there is a repair method (see Technical Note 6015A, Repairing electrical wiring,
