Inspection Procedure
WARNING: This page is about a different car, the 2008 Toyota Yaris. However, it is still accessible from the selected car via links, so may be relevant.
- INSPECT TRANSMISSION WIRE (SHIFT SOLENOID VALVE SLU)
- Disconnect the transmission wire connector from the transaxle.
- Measure the resistance.

NG: REPAIR OR REPLACE HARNESS OR CONNECTOR
OK: REPLACE ECM (See REMOVAL )
- INSPECT SHIFT SOLENOID VALVE SLU
- Remove shift solenoid valve SLU.
- Measure the resistance.
Standard resistance
STANDARD RESISTANCE SPECIFICATIONTester Connection Specified Condition 1 - 2 5.0 Ω to 5.6 Ω at 20°C (68°F) - 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 operating sounds.
NG: REPLACE SHIFT SOLENOID VALVE SLU (See DISASSEMBLY )
OK: REPAIR OR REPLACE TRANSMISSION WIRE (See REMOVAL )
