Location of engine management system relays and fuses under the instrument panel console
Note: The right instrument panel console trim has been removed (see "Instrument panel - removal").
Engine Management System Relays and Fuses: 1,2 and 6 - fuses (see table 8.4.3); 3 - main relay; 4 - relay for switching on the electric fan of the engine cooling system; 5 - fuel pump relay
Table 8.4.3. Engine management system fuses

* The first years of production of cars were equipped with 15 A fuses.
The fuse and relay mounting block contains tweezers for removing fuses (see "Fuse and relay mounting block").
A faulty fuse can be identified by a burnt-out filament.
Recommendation: Sometimes the fuse thread remains intact, while its connection inside the fuse is broken. It is impossible to visually determine such a malfunction. In this case, you can evaluate the condition of the fuse using an ohmmeter.
Warning! Before replacing a fuse, it is necessary to determine and eliminate the cause of the fuse blown. To avoid failure of the engine management system components, fuses with an increased rating or homemade ones must not be installed.
