General instructions regarding the injection system
t  The Engine control unit -J623- is equipped with a self-diagnosis system. Before carrying out repairs, and for troubleshooting, refer to the event memory. Likewise, check vacuum lines and connections (air infiltration).
t  The fuel hoses in the engine compartment must only be secured with spring clamps. Using retaining clamps or screwed clamps is not allowed.
t  A minimum voltage of 11.5V is necessary for the perfect operation of electrical components.
t  Do not use silicone-based sealants. Silicone residues sucked in by the engine do not burn and may damage the Lambda Probe -G39-.
