Injection system fuses and relays

INJECTION SYSTEM FUSES AND RELAYS

General system protection fuse

The general fuse (EFI-30A) protecting the injection-ignition system (1) is housed inside a container; to gain access to the fuse, undo side clips and lift lid.

Fuses and relays

The following components are housed on a bracket located against the rear wall of the engine bay:

1. Lambda probe lead junction
2. 5A ECU fuse
3. 20A fuse for components supplied through dual relay (electric pump, lambda probe, injectors and fuel vapour cut-off solenoid)
4. Dual relay

Unscrew ring nut and remove cover to gain access to the above components.

EARTH POINTS

The earth of the injection-ignition system and earth of the electronic control unit are both fixed to the left hand side of the engine, close to the exhaust valves cover.

NOTE The air cleaner-butterfly valve case connecting sleeve and ignition coils are not shown in the figure alongside in order to illustrate the position of the earth points more clearly. No components require removal in order to gain access to the earths.
