CAUTION / NOTICE / HINT

NOTICE:

Inspect the fuses for circuits related to this system before performing the following inspection procedure.

PROCEDURE

1.	INSPECT WIRELESS CHARGER MAIN SWITCH (MOBILE WIRELESS CHARGER SWITCH)

(a) Remove the wireless charger main switch (mobile wireless charger switch) (See page ).

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

Standard Resistance:

Tester Connection	Condition	Specified Condition
M7-11 (ACC) - M7-12 (GND)	Wireless Charger Main Switch (Mobile Wireless Charger Switch) is on (not protruding)	Below 1 Ω
M7-11 (ACC) - M7-12 (GND)	Wireless Charger Main Switch (Mobile Wireless Charger Switch) is off (protruding)	10 kΩ or higher
