• Other precautions
(a) Before carrying out welding, place a cover over
electronic devices, rubber hoses, wire
harnesses, pipes, tubes, chassis spring, tires
and other items in the vicinity of the welding
area in order to protect them from sparks
(spatter) generated during welding.
Please note that you cannot protect the ECU
from damage caused by a short circuit if you
accidentally touch the ECU case with the
welding rod.
(b) Carry out welding under appropriate conditions,
take steps to minimize the effect of heat on the
vicinity, and also strive to secure high welding
quality.
• Checks to be performed after the end of welding
work
(a) Reconnect the battery cables that you discon-
nected from the positive and negative
terminals, so as to restore the power.
If you removed the paint from the frame or the
cabin, apply rustproofing paint of the same
color.
(b) Confirm that the starter switch is OFF.
(c) If you wait for at least 30 seconds before
reconnecting the battery cables that you
disconnected from the positive and negative
terminals in step (a), the needle of each meter
in the meter cluster will move. Note, however,
that this is due to the operation the
self-diagnostic function, and is not indicative of
a fault.
(d) After restoring the power, check the electronic
devices to see if they function correctly.
For the checking method, consult an authorized
MITSUBISHI FUSO dealer.
(e) For the precautions to observe concerning the
SRS airbag when carrying out welding work,
refer to É 6.13.1.
