GI-6 GENERAL INFORMATION
ELECTRONIC PARTS
Vehicles today include a great many electronic parts and
components, and these are in general very susceptible to
adverse effects caused by overcurrent, reverse current,
electromagnetic waves, high temperature, high humidity
impacts, etc.
In particular such electronic components can be damaged
if there is a large current flow during welding from the body
side.
Therefore, take the following precautions during body repair
to prevent damage to the CONTROL MODULES (ECM,
TCM, ABS CM, SRS CM, etc.)
1. Before removing and inspecting the electrical parts or
before starting electric welding operations, disconnect
the negative (-) terminal cable from the battery.
2. Do not expose the CONTROL MODULES to ambient
temperatures above 80 C (176 F ).
If it is possible the ambient temperatures may reach
80 C (176 F) or more, remove the CONTROL
MODULES from the vehicle before starting work.
3. Be careful not to drop the CONTROL MODULES and
not to apply physical shocks to them.
