Servicing the Electrical System
1. Prior to servicing the electrical system, be sure to
turn off the ignition switch and disconnect the
battery ground cable.
NOTE : When performing MFI or ELC system
diagnosis, if the battery cable is removed, then, any
diagnostic trouble code retained by the computer will
be cleared. There fore, if necessary, read the
diagnostic trouble code before removing the battery
cable.
2. Secure the wiring harnesses with clamps so that
there is no slack. However, allow some slack or
distance for the wiring harness from vibrating
parts, which crosses the engine or other vibrating
parts of the vehicle. Allow wiring harness some
slack or distance so that it does not contact with
any of the adjacent parts, and then, secure the
harness by using a clamp.
3. If any section of a wiring harness interferes with
the edge of parts, or corners, wrap the section of
the harness with tape or something similar in
order to protect if from damage.
4. When installing any parts, be careful not to pinch
or damage any of the wiring harness.
5. Never throw relays, sensors or electrical parts, or
expose them to strong shock.
