OTHER PRECAUTIONS
DANGER
Make sure that electrical current or air
pressure is removed before performing any
work. A part may be energized even if the
ignition switch is OFF. A part may be under
pressure even if all tanks are empty. Before
performing any work on the vehicle, refer to
wiring diagrams and/or air schematics to
thoroughly understand the system.
CAUTION
Disconnect all electronic control modules
before welding. If modules (ECM, TCM, ECU,
ABS) are not disconnected before welding is
done, there is a high risk of destroying the
electronic components (EPROM, Chip). Refer
to procedure described in Maintenance
Manual.
