Power Distribution Box
WARNING:
Always disconnect the battery before servicing high current fuses.
WARNING:
To reduce risk of electrical shock, always replace the cover to the power distribution box before reconnecting the battery or refilling fluid reservoirs. |
The power distribution box is in the engine compartment. It has high-current fuses that protect your vehicle's main electrical systems from overloads.
If you disconnect and reconnect the battery, you will need to reset some features. See
Changing the 12V Battery.
