Inspection Procedure

1. Disconnect the transmission wire connector from the transmission.
2. Measure the resistance according to the value(s) in TRANSMISSION WIRE (SLU) (RESISTANCE)  .

   Standard resistance 

   TRANSMISSION WIRE (SLU) (RESISTANCE)
   
   

   Tester Connection	Specified Condition 20°C (68°F)
   12 (SLU+) - 4 (SLU-)	5.0 to 5.6 ohms

3. Measure the resistance according to the value(s) in TRANSMISSION WIRE (SLU) (CHECK FOR SHORT)  .

Standard resistance (Check for short) 

NG: GO TO STEP   3 

OK: Go To Next Step 

1. Connect the transmission wire connector to the transmission.
2. Disconnect the ECM connector.
3. Measure the resistance according to the value(s) in TRANSMISSION WIRE - ECM (RESISTANCE)  .

   Standard resistance 

   TRANSMISSION WIRE - ECM (RESISTANCE)
   
   

   Tester Connection	Specified Condition 20°C (68°F)
   E4-13 (SLU+) - E4-12 (SLU-)	5.0 to 5.6 ohms

4. Measure the resistance according to the value(s) in TRANSMISSION WIRE - ECM (CHECK FOR SHORT)  .

Standard resistance (Check for short) 

NG: REPAIR OR REPLACE HARNESS OR CONNECTOR 

OK: REPLACE ECM 

1. Remove the shift solenoid valve SLU.
2. Measure the resistance according to the value(s) in SHIFT SOLENOID VALVE SLU  .

   Standard resistance 

   SHIFT SOLENOID VALVE SLU
   
   

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

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 SLU 

OK: REPAIR OR REPLACE TRANSMISSION WIRE
