WARNING: This page is about a different car, the 2005 Toyota 4Runner. However, it is still accessible from the selected car via links, so may be relevant.
HINT:
- The shift solenoid valve S1 is turned on/off normally when the shift lever is in the D position:SHIFT LEVER POSITION CHART
ECM command gearshift 1st 2nd 3rd 4th 5th Shift solenoid valve S1 ON ON OFF OFF OFF
- INSPECT TRANSMISSION WIRE(S1)
- Disconnect the transmission wire connector from the transmission.
- Measure the resistance according to the value(s) in the table below.
Standard:
TESTER CONNECTION SPECIFIED CONDITION (1 OF 3)Tester Connection Specified Condition 20°C (68°F) 8 - Body ground 11 to 15 Ω
- NG: Go to step 3
- OK: GO TO NEXT STEP
- CHECK HARNESS AND CONNECTOR(TRANSMISSION WIRE - ECM)
- Connect the transmission connector to the transmission.
- Disconnect the connector from the ECM.
- Measure the resistance according to the value(s) in the table below.
Standard:
TESTER CONNECTION SPECIFIED CONDITION (2 OF 3)Tester Connection Specified Condition 20°C (68°F) E5-11 (S1)-Body ground 11 to 15 Ω
- NG: REPAIR OR REPLACE HARNESS OR CONNECTOR (SEE ELECTRONIC CIRCUIT INSPECTION PROCEDURE )
- OK: GO TO NEXT STEP
REPLACE ECM (1GR-FE)
- INSPECT SHIFT SOLENOID VALVE(S1)
- Remove the shift solenoid valve S1.
- Measure the resistance according to the value(s) in the table below.
Standard:
TESTER CONNECTION SPECIFIED CONDITION (3 OF 3)Tester Connection Specified Condition 20°C (68°F) Solenoid Connector (S1) - Solenoid Body (SI) 11 to 15 Ω - Connect the positive (+) lead to the terminal of the solenoid connector, and the negative (-) lead to the solenoid body.
OK:
The solenoid makes an operating sound.
- NG: REPLACE SHIFT SOLENOID VALVE (S1) (SEE TRANSMISSION VALVE BODY ASSY (A750E/A750F) )
