De façon connue le dispositif d'allumage représenté à la figure 1 est constitué d'un capteur 3 dont les signaux sont amplifiés par un module électronique 2 pour commander l'état d'une bobine élévatrice de tension 4 dont la tension secondaire est ensuite envoyée à des bougies 9 par l'intermédiaire d'un distributeur 5. Le module 2 comporte un connecteur 8 complémentaire à un connecteur 7 qui correspond au faisceau 6 du dispositif d'allumage du véhicule. Conformément à l'invention l'appareil de contrôle 1 comporte d'une part un connecteur 30 équivalent au connecteur 7 et donc complémentaire au connecteur 8 et d'autre part un connecteur 20 équivalent au connecteur 8 et complémentaire au connecteur 7, de façon à permettre, sans modification de l'emplacement des différents éléments constitutifs de l'allumage et sans repérage des fils électriques du réseau, l'insertion de l'appareil diagnostic (1) dans le réseau de l'allumage tel que représenté à la figure 2, et ainsi à éviter tout risque d'erreur de branchement;In known manner the ignition device shown in Figure 1 consists of a sensor 3 whose signals are amplified by an electronic module 2 to control the state of a voltage booster 4 whose secondary voltage is then sent to spark plugs 9 via a distributor 5. The module 2 comprises a connector 8 complementary to a connector 7 which corresponds to the harness 6 of the vehicle ignition device. According to the invention the control device 1 comprises on the one hand a connector 30 equivalent to the connector 7 and therefore complementary to the connector 8 and on the other hand a connector 20 equivalent to the connector 8 and complementary to the connector 7, so as to allow, without modifying the location of the various constituent elements of the ignition and without locating the electrical wires of the network, the insertion of the diagnostic device (1) into the ignition network as shown in FIG. 2 , and thus to avoid any risk of connection error;

Un tel appareil de diagnostic comporte essentiellement les deux connecteurs 20 et 30, deux basculeurs 10 et 100, un réducteur de tension 40, un comparateur 50, un générateur de signaux 70, deux systèmes de visualisation 60 et 80.Such a diagnostic device essentially comprises the two connectors 20 and 30, two rockers 10 and 100, a voltage reducer 40, a comparator 50, a signal generator 70, two display systems 60 and 80.

Le connecteur 20 relie l'appareil 1 au capteur 3 par des connexions 21 et 22, à l'alimentation 12v par une connexion 23 et à la bobine 4 par des connexions 24, 25.The connector 20 connects the device 1 to the sensor 3 by connections 21 and 22, to the power supply 12v by a connection 23 and to the coil 4 by connections 24, 25.

L'utilisation d'un tel appareil est alors la suivante : le moteur du véhicule étant arrêté et le contact coupé il suffit de déconnecter les connecteurs 7 et 8 puis de relier l'appareil 1 par son connecteur 20 au connecteur 7 c'est à dire au capteur 3 par les connexions 21 et 22, à la batterie par la connexion 23 et à la bobine 4 par les connexions 24 et 25.The use of such a device is then as follows: the vehicle engine being stopped and the ignition off, it suffices to disconnect the connectors 7 and 8 and then to connect the device 1 by its connector 20 to the connector 7. tell the sensor 3 by connections 21 and 22, the battery by connection 23 and the coil 4 by connections 24 and 25.

Le fonctionnement d'un tel appareil est alors le suivant : les différents interrupteurs 13 à 15 de l'ensemble basculeurs 10 étant dans les positions 13Q, 14a et 15a telles que représentées en trait plein à la figure 3, si le voyant vert 61, du système de visualisation 60, s'allume la tension d'alimentation est correcte, si ce voyant vert 61 reste éteint il existe un problème d'alimentation venant soit de la batterie, soit du faisceau électrique, soit d'un contact électrique, il est donc nécessaire d'effectuer les vérifications avant de poursuivre, d'autre part si les voyants 81 et 82 du système de visualisation 80 sont éteints, le capteur 3 est en bon état ainsi que la liaison électrique le concernant, par contre si le voyant 81 est allumé, le capteur 3 est coupé, alors que si le voyant 82 reste allumé cela signifie que le capteur 3 est en court circuit, il est donc nécessaire d'effectuer les modifications adéquates avant de poursuivre les tests.The operation of such an apparatus is then as follows: the various switches 13 to 15 of the rocker assembly 10 being in positions 13 Q , 14a and 15a as shown in solid lines in FIG. 3, if the green indicator 61 , of the display system 60, lights up the supply voltage is correct, if this green light 61 remains off there is a supply problem coming either from the battery, or from the electrical harness, or from a electrical contact, it is therefore necessary to carry out the checks before continuing, on the other hand if the lights 81 and 82 of the display system 80 are off, the sensor 3 is in good condition as well as the electrical connection concerning it, by against if the light 81 is on, the sensor 3 is cut, while if the light 82 remains on it means that the sensor 3 is in short circuit, it is therefore necessary to make the appropriate modifications before continuing the tests.

Ces contrôles effectués le connecteur 30 peut être relié au module 2 par l'intermédiaire de son connecteur 8, l'inverseur 101 du basculeur 100 est placé dans la position 101 a, le test est lancé en appuyant quelques secondes sur un bouton poussoir 11 de l'ensemble basculeurs 10, qui alimente un relais 12 lequel commande les interrupteurs 13 à 15 qui viennent dans les positions 13b, 14b et 15b. Pendant ce lancement le système de signalisation 80 clignote et la lampe rouge 62 est allumée.Le bouton poussoir 11 est alors relaché et si la lampe rouge 62 s'éteint et que la lampe verte 61 s'allume la batterie et le capteur, le module et le primaire bobine sont en bon état le défaut recherché se situe donc au niveau du secondaire bobine ou des bougies ou du faisceau HT.Once these checks have been carried out, the connector 30 can be connected to the module 2 via its connector 8, the inverter 101 of the rocker 100 is placed in position 101 a, the test is launched by pressing a push button 11 for a few seconds. the rocker assembly 10, which supplies a relay 12 which controls the switches 13 to 15 which come in positions 13b, 14b and 15b. During this launching, the signaling system 80 flashes and the red lamp 62 is on. The push button 11 is then released and if the red lamp 62 goes out and the green lamp 61 turns on the battery and the sensor, the module and the primary coil are in good condition the fault sought is therefore at the secondary coil or the spark plugs or the HV harness.

Si le voyant rouge reste allumé une défaillance existe au niveau du module ou du primaire bobine.If the red light stays on, a fault exists in the module or the primary coil.

L'inverseur 101 est ensuite basculé en sa position 101 b, le dispositif est relancé comme précédemment par le bouton poussoir 10 qui est ensuite relâché, si la lampe rouge 62 s'éteint et que la lampe verte 61 s'allume, la batterie, le capteur et le module sont en état, par contre le primaire bobine ou la liaison de la bobine au module sont défaillants, il faut donc effectuer la réparation, si la lampe rouge 62 reste allumée le module 2 est défaillant, il faut donc le remplacer.The inverter 101 is then tilted to its position 101 b, the device is restarted as before by the push button 10 which is then released, if the red lamp 62 goes out and the green lamp 61 comes on, the battery, the sensor and the module are in good condition, on the other hand the primary coil or the connection of the coil to the module are faulty, repair must therefore be carried out, if the red lamp 62 remains on, module 2 is faulty, it must therefore be replaced .

Il n'y a plus qu'à couper le contact, à déconnecter l'appareil 1 et à relier les connecteurs 7 et 8.All you have to do is switch off the ignition, disconnect the device 1 and connect the connectors 7 and 8.

Un tel appareil à l'avantage essentiel d'être d'un emploi simple et de permettre une localisation par étape de tout défaut éventuel d'un dispositif d'allumage.Such an apparatus has the essential advantage of being simple to use and of enabling location by stage of any possible defect in an ignition device.
