1. INSPECT TRANSMISSION WIRE (SL2) 
   1. Disconnect the transmission wire connector from the transmission.
   2. Measure the resistance according to the value(s) in the table below.

      Standard resistance

      Tester Connection	Specified Condition 20°C (68°F)
      10 (SL2+) - 2 (SL2-)	5.0 to 5.6 Ω

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

      Standard resistance (Check for short)

   NG:  Go to step  3

   OK: Go to next step 

2. CHECK HARNESS AND CONNECTOR (TRANSMISSION WIRE - ECM) 
   1. Connect the transmission connector to the transmission.
   2. Disconnect the connector from the ECM.
   3. Measure the resistance according to the value(s) in the table below.

      Standard resistance

      Tester Connection	Specified Condition 20°C (68°F)
      E4-11 (SL2+) - E4-10 (SL2-)	5.0 to 5.6 Ω

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

   NG: REPAIR OR REPLACE HARNESS OR CONNECTOR 

   OK: REPLACE ECM 

3. INSPECT SHIFT SOLENOID SL2 
   1. Remove the shift solenoid valve SL2.
   2. Measure the resistance according to the value(s) in the table below.

      Standard resistance

   3. Connect the positive (+) lead with 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 SL2 

   OK: REPAIR OR REPLACE TRANSMISSION WIRE
