of the injection computer connector, 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(s), otherwise replace the wiring.
Check the insulation, continuity and the absence of interference resistance on the following connections:
–3FB between components 371 and 1047 (for Logan, Sandero, Duster) or 238 (for Thalia 2/Symbol 2, Kangoo
VLL) or 983 (for Clio II F 6),
