To test for battery drain you need a multi meter to test current. You unhook the positive battery cable and hook the multi meter up in series. This will give you your initial reading. From there you need to let the vehicle sit for 1 hour so the modules go to sleep and recheck the reading. If your drain remains above .060milliamps you need to remove fuses 1 at a time until you isolate where the battery drain is coming from. Once you know what fuse is causing the battery drain you can determine what is causing the issue.
