Note: In recent years of production, the engine management system has been modified: a camshaft position sensor, an ignition coil, and a diagnostic connector block with digital terminal numbering have been installed (the same as in the engine management system 11183). The rating of fuses F1 and F2 has been changed to 7.5 A.
