1.2 PRECAUTION FOR ELECTRICAL
CIRCUIT SERVICE:
•
Disconnect the negative cable of the battery
while servicing the electrical parts that do not
require battery power and insulate the
negative terminal properly.
•
While removing the battery first disconnect
the negative cable and then the positive
cable. While reinstalling the battery, first
connect the positive cable and then negative
cable.
•
Be sure to turn the ignition switch off before
disconnecting and connecting coupler to
avoid electronic parts damage
•
Do not touch the electrical terminals of parts
which use microcomputers (e.g. electronic
control units like ECM etc.) to avoid damage
to these parts from static electricity from your
body
•
Always use the correct voltmeter, ohmmeter
for taking measurement to avoid damage to
the electronic control unit and sensors.
•
Make sure to insert the probe from wire
harness side of the connector for taking
measurement.
•
Make sure the connector halves are mating
properly and terminals seating precisely in the
connector body.
•
Dirt / corroded terminals result in improper
contact. The terminals should be cleaned
carefully.
•
Improper contact pressure between mating
terminals disturbs the connectivity between
them.
•
Replace the damaged connector body to
avoid exposure of the terminals in case of
inadequate contact pressure.
