   Refer to DISASSEMBLY [09/2015 - ]

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

   Standard Resistance

   Tester Connection	Condition	Specified Condition
   Shift solenoid valve SL1 connector terminal 1 - terminal 2	20°C (68°F)	5.0 to 5.6 Ω
   Shift solenoid valve SL2 connector terminal 1 - terminal 2	20°C (68°F)	5.0 to 5.6 Ω
   Shift solenoid valve SL3 connector terminal 1 - terminal 2	20°C (68°F)	5.0 to 5.6 Ω
   Shift solenoid valve SL4 connector terminal 1 - terminal 2	20°C (68°F)	5.0 to 5.6 Ω
   Shift solenoid valve SL5 connector terminal 1 - terminal 2	20°C (68°F)	5.0 to 5.6 Ω

3. Connect a positive (+) lead from the battery to terminal 1 and a negative (-) lead with a 21 W bulb to terminal 2 of the solenoid valve connector. Check that the valve moves and makes an operating sound.

   OK

   Valve moves and makes an operating sound.
