Attention! All work related to replacing fuses and relays must be performed only after disconnecting the wire from the battery terminal.
Attention! Before replacing a fuse, it is necessary to determine and eliminate the cause of the fuse blowing. To avoid failure of the engine management system components, fuses with an increased rating or homemade ones must not be installed.
Brown fuses are rated at 7.5 A, blue fuses are rated at 15 A.
