MAINTENANCE AND LUBRICATION
471
Attempting to work on electronic components without
proper equipment can damage internal parts with
static electricity.
Today's vehicles contain a high number of electronic
devices. It is very important to exercise caution when
working on a modern electrical system, charging
batteries or jump starting the engine. To minimize the
risk of any damage to the electronic components,
follow the procedures below when work is being done
to the electrical system.
Welding on the vehicle can damage the electrical
system or components due to the high voltage and
current spikes that normally occur when welding. It is
preferable to avoid welding on an assembled vehicle.
However, if any structure on or in contact with the
vehicle must be welded, follow the recommendations
below.
If there are other ground cables connected to the
battery (such as engine ECU, transmission ECU, etc.),
disconnect those wires first, then remove the main
battery ground cable. Electronic modules may be
damaged when their ground(s) are
connected/disconnected with the main battery ground
disconnected. Therefore, disconnect the main battery
ground last or when installing, connect the main
ground first.
