NG: REPAIR OR REPLACE HARNESS OR CONNECTOR 

OK: REPLACE ECM (for 2ZR-FE)  (See REMOVAL )

1. Remove the shift solenoid valve SLT.
2. Measure the resistance according to the value(s) in the table below.

   Tester Connection	Condition	Specified Condition
   1-2	20°C (68°F)	5.0 to 5.6 Ω

3. Connect the positive (+) lead with a 21 W bulb to terminal 2 and the negative (-) lead to terminal 1 of the solenoid valve connector, then check the movement of the valve.

   OK: 

   The solenoid makes an operating sound. 

   NG: REPLACE SHIFT SOLENOID VALVE SLT  (See DISASSEMBLY )
