8 (CTY) - 7 (E)	Half-latch	Below 1 Ω
8 (CTY) - 7 (E)	Half-latch → Full-latch	Below 1 Ω → 10 kΩ or higher
8 (CTY) - 7 (E)	Full-latch	10 kΩ or higher
8 (CTY) - 7 (E)	Over-latch	10 kΩ or higher

If the result is not as specified, replace the back door lock assembly.

(e) Check the operation of the selector switch.

(1) Measure the resistance according to the value(s) in the table below.

Standard Resistance:

Tester Connection	Condition	Specified Condition
