Precautions when servicing electrical system
l Note the following items when servicing the electrical system.
l Do not alter the wiring or electrical equipment in any way as this may damage the vehicle or cause a fire
due to shorting or overcapacity of a circuit.
l Always disconnect the negative (- ) battery cable first and 0 Replace blown fuses with ones having the same designated

Zaution
l Be sure that the ignition and other switches are OFF
before disconnecting or connecting the battery
terminals.
Failure to do so may damage the semi-conductor
components. Caution l Replacing a fuse with one of a larger capacity than
designated may damage components or cause an electrical
fire.

Caution
l Clamp all harnesses near vibrating components(e.g.
the engine) to remove any slack and prevent Contact
due to vibration.

II-GM6 Troubleshooting
Finding short circuits
Shorts occur between the power(positive) and ground(negative) sides of a circuit.
Therefore, finding a shdit circuit requires determining how the circuit is routed.
Circuits not connected to control unit
Examples
Indication
0 Fuse melts. Finding short circuit
0
Test lamp 1. Remove the fuse and
main fuse of the circurt.
2. Disconnect all connectors
of electrical components
in the circuit.
3. Attach a voltmeter or test
lamp to the fuse box and
reconnect each
connector, beginning
nearest the power
source.
4. Check the voltmeter or
see if the test lamp lights
as the connectors are
connected. Finding short circuit

1. Remove the fuse and main
fuse of the circuit.
2. Disconnect all connectors of

Sensor/switch
1. Attach the test lamp or
voltmeter to the CPU
