I7-1 (GND) - Body ground	Always	Below 1 Ω

*a	Component with harness connected (Front Power Window Regulator Motor Assembly RH)

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

Standard Voltage:

Tester Connection	Switch Condition	Specified Condition
I7-2 (B) - I7-1 (GND)	Ignition switch off	11 to 14 V

GO TO STEP 7

REPAIR OR REPLACE HARNESS OR CONNECTOR

5.	CHECK HARNESS AND CONNECTOR (REAR POWER WINDOW REGULATOR MOTOR ASSEMBLY LH - BATTERY AND BODY GROUND)
