Spot-check the battery heating function after it is closed. The closeout spot check should go back over the function menu, the low-temperature condition, and the system fault codes, and confirm that the corrected document has replaced the old file and reached every user. For the battery heating function file, this cross-border vehicle procurement guide supports the check of earlier and later records. After the check is done, write the conclusion and the document deadline into the battery heating acceptance sheet and hand it to the next role.
