Inspection Procedure

HINT:

• The shift solenoid valve SL1 is turned on/off normally when the shift lever is in the D position:

  Shift solenoid valve SL1	OFF	OFF	OFF	OFF	ON	ON

1. INSPECT TRANSMISSION WIRE (SL1) 
   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)
      11 (SL1+) - 3 (SL1-)	5.0 to 5.6 Ω

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

      Tester Connection	Specified Condition
      11 (SL1+) - Body ground	10 kΩ or higher
      3 (SL1-) - Body ground	↑

   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)
      E4-25 (SL1+) - E4-24 (SL1-)	5.0 to 5.6 Ω

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

      Standard resistance (Check for short) 

      TESTER CONNECTION SPECIFIED CONDITION CHART
      
      

      Tester Connection	Specified Condition
      E4-25 (SL1+) - Body ground	10 kΩ or higher
      E4-24 (SL1-) - Body ground	↑

   NG: REPAIR OR REPLACE HARNESS OR CONNECTOR 

   OK: REPLACE ECM 

3. INSPECT SHIFT SOLENOID VALVE SL1 
   1. Remove the shift solenoid valve SL1.
   2. Measure the resistance according to the value(s) in the table below.

      Standard resistance 

      TESTER CONNECTION SPECIFIED CONDITION CHART
      
      

      Tester Connection	Specified Condition 20°C (68°F)
      1-2	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.
