Checking the main power relay
1. Check for constant conductivity between terminals "1" and "2" of the relay.
2. Check for conductivity between terminals "3" and "5" of the relay when applying battery voltage between terminals "1" and "2".
Checking the main window switch
1. Checking the work.
2. Check the switch circuit. Check that there is conductivity between terminals "20" and "9", "B" and "9".
3. Checking the backlight. Connect (+) of the battery to terminal "4", (-) to terminal 96, check that the backlight of the driver's window switch works.

a) Connect the ammeter to terminal "1" (right door Camry, left door Vista) or "2" (left door Camry, right door Vista).
b) Close the glass completely.
c) Check that when the glass is completely lowered, the current is approximately 16 - 23 A.
d) While continuing to hold the window switch, check that the thermal fuse operates within 4 to 40 seconds (when the thermal fuse is triggered, it makes a characteristic sound).
d) Check that the windows start working again after 60 s.
Checking the central control unit
Check the circuit according to the table "Checking the central control unit".
