Inspection Procedure

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 SL2 is turned on/off normally when the shift lever is in the D position:

ECM COMMAND GEARSHIFT REFERENCE

ECM command gearshift	1st	2nd	3rd	4th	5th
Shift solenoid valve SL2	ON	ON	ON	ON	OFF

INSPECT TRANSMISSION WIRE(SL2)

Disconnect the transmission wire connector from the transmission.

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 - 17 (SL2+) - E5 - 16 (SL2-)	5.0 to 5.6 Ω

NG: REPAIR OR REPLACE HARNESS OR CONNECTOR (SEE ELECTRONIC CIRCUIT INSPECTION PROCEDURE )
OK: GO TO NEXT STEP.

REPLACE ECM (2UZ-FE)

INSPECT SHIFT SOLENOID VALVE(SL2)

Remove the shift solenoid valve SL2.

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)
1 -2	5.0 to 5.6 Ω

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.
