The Multec combined ignition/injection system is equipped with self-diagnosis. Faults that occur are stored as trouble codes and can be read off via the engine telltale as blink codes or using TECH 1/TECH 1A via the diagnostic plug. The diagnostic plug is in the fuse box (see illus.). For more detailed information and for checking the entire system see Checking Procedures "Multec Central Fuel Injection". |
