Safety measures for electronic control equipment before performing arc welding
The following safety measures must be observed to protect the electronic control equipment against excessive voltage during arc welding:
- Remove terminal on negative pole of battery and cover negative pole on battery.
- On vehicles with airbag disconnect the red, 12-pin test connector/plug connector after waiting at least two seconds after battery is disconnected (danger of erroneous actuation).
- Connect ground terminal of arc welder directly to part to be welded. Ensure that no electrically insulating parts are located between the ground connection and point to be welded.
- Do not touch electronic control equipment and electrical leads with the ground connection or welding electrode.
NOTE:
It is not necessary to disconnect the electrical plug connector on any of the other electronic control equipment (e.g. CIS-E control unit, etc.).
