October 30: LEMON manuals on a temporary server, it is slow and having issues, download the manuals you need! Later in November we will switch back to the fast server.

Measure the switch resistance.

NOTE:

Make sure the battery voltage is applied to the terminal No. 13(+) and 5(-), when measuring resistance, because the main switch is controlled by microcomputer.
Make sure that the window lock switch is measured in the UNLOCK position.
