Battery Module Switch

The battery module switch is connected in series to the battery module fuse. Always turn the battery module switch to the OFF position whenever service or checks are required on or around the high voltage circuits. Follow these steps exactly:

1. Remove the switch cover from the IPU lid, then turn the switch OFF.
2. Wait at least 5 minutes.
3. Remove the IPU lid.
4. Measure the voltage at the output terminals. Make sure the voltage is low enough for safe operation before any service is done.
