CHECKING CABLES AND WIRES1. Check connections for looseness, rust and stains.
2.Check terminals and wires for corrosion by battery electro-
lyte, etc.
3.Check terminals and wires for open circuit or impending
open circuit.4. Check wire insulation and coating for damage, cracks
and degrading.
5.Check conductive parts of terminals for contact with other
metallic parts (vehicle body and other parts).6. Check grounding parts to verify that there is complete
continuity between attaching bolt(s) and vehicle body.7. Check for incorrect wiring.
8.Check that wirings are so clamped as to prevent contact
with sharp corners of the vehicle body, etc. or hot parts(exhaust manifold, pipe, etc.).
9.Check that wirings are clamped firmly to secure enough
clearance from the fan pulley, fan belt and other rotating
or moving parts.
10. Check that the wirings between the fixed parts such as
the vehicle body and the vibrating parts such as the engine
are made with adequate allowance for vibrations.
HANDLING ON-VEHICLE BATTERY
When checking or servicing does not require power from the
on-vehicle battery, be sure to disconnect the cable from thebattery
(-) terminal. This is to prevent problems that could
be caused by a short circuit. Disconnect the (-) terminal first
and reconnect it last.
Caution1. Before connecting or disconnecting the negative
cable, be sure to turn off the ignition switch and the
lighting switch.
(If this is not done, there is the possibility of semicon-
ductor parts being damaged.)
2.After completion of the work steps [when the battery’s
negative (-)
terminal is connected], warm up the engineand allow it to idle for approximately five minutes
under the conditions described below, in order to sta-
bilize the engine control conditions, and then checkto be sure that the idling is satisfactory.
Engine coolant temperature:
85-95°C (185-203°F)
Lights, electric fans, accessories: OFF
Transaxle: neutral position
(A/T models: “N” or “P”)
Steering wheel: neutral (center) position
