Testing the Fuses
Electrical System: Testing the Electrical Components
In addition to the fuses in the fuse block, a 25 A fuse is included in the engine
wire harness to protect the power circuit to the ECU. This fuse is located near
the ECU (Figure 172).
Refer to Figure 171 to identify each individual fuse and its correct amperage in
the fuse block. The fuses have the following functions.
The fuse F1 (15 A) protects power supply for the key switch circuits and optional
light kit.
The fuse F2 (10 A) protects the SCM start circuit.
The fuse F3 (10 A) protects the SCM power, hour meter, InfoCenter, and parking
brake sensor.
The fuse F4 (2 A) protects power supply for the SCM logic.

but not at the other, the fuse is damaged.
If the fuse removal is necessary, ensure that the key switch is in the O
