2. Measure the resistance according to the value(s) in the table below.
   STANDARD RESISTANCE
   
   

   Tester Connection	Switch Condition	Specified Condition
   2 (MSM-) - 5 (MSE)	Satellite switch set LH is pressed	Below 1 Ω
   2 (MSM-) - 5 (MSE)	Satellite switch set LH is not pressed	10 kΩ or higher
   3 (MSSL) - 5 (MSE)	Satellite switch set ON/OFF is pressed	Below 1 Ω
   3 (MSSL) - 5 (MSE)	Satellite switch set ON/OFF is not pressed	10 kΩ or higher
   4 (MSM+) - 5 (MSE)	Satellite switch set RH is pressed	Below 1 Ω
   4 (MSM+) - 5 (MSE)	Satellite switch set RH is not pressed	10 kΩ or higher

1. Disconnect the J35 connector.
2. Measure the resistance according to the value(s) in the table below.
   STANDARD RESISTANCE
   
   

   Tester Connection	Condition	Specified Condition
   J35-5 (VSW) - J16-4 (MSM+)	Always	Below 1 Ω
   J35-6 (MSW) - J16-2 (MSM-)	Always	Below 1 Ω
   J35-7 (SW) - J16-3 (MSSL)	Always	Below 1 Ω
   J16-2 (MSM-) - Body ground	Always	10 kΩ or higher
   J16-3 (MSSL) - Body ground	Always	10 kΩ or higher
   J16-4 (MSM+) - Body ground	Always	10 kΩ or higher

NG → REPAIR OR REPLACE HARNESS OR CONNECTOR
