Inspection Procedure
WARNING: This page is about a different car, the 2004 Toyota Corolla. However, it is still accessible from the selected car via links, so may be relevant.
- INSPECT TRANSMISSION WIRE (SLT)
- Disconnect the transmission wire connector from the transaxle.
- Measure the resistance according to the value (s) in the table below.
Standard:
TESTER CONNECTION RESISTANCE SPECIFICATIONTester Connection Specified Condition 20 °C (68 °F) 1 (SLT+) - 4 (SLT-) 5.0 to 5.6 Ω - Measure the resistance according to the value (s) in the table below.
Standard (Check for short):
- NG: Go to step 3
- OK: GO TO NEXT STEP.
- CHECK HARNESS AND CONNECTOR (TRANSMISSION WIRE-ECM)
- Connect the transmission wire connector to the transaxle.
- Disconnect the ECM connector.
- Measure the resistance according to the value (s) in the table below.

Standard:
TESTER CONNECTION RESISTANCE SPECIFICATIONTester Connection Specified Condition 20 °C (68 °F) E3 - 17 (SLT+) - E3 - 16 (SLT-) 5.0 to 5.6 Ω - Measure the resistance according to the value (s) in the table below.
Standard (Check for short):
- NG: REPAIR OR REPLACE HARNESS OR CONNECTOR (See ELECTRONIC CIRCUIT INSPECTION PROCEDURE )
- OK: REPLACE ECM (See REPLACEMENT )
- INSPECT SHIFT SOLENOID VALVE (SLT)
- Remove the shift solenoid valve (SLT).
- Measure the resistance according to the value (s) in the table below.
Standard:
TESTER CONNECTION RESISTANCE SPECIFICATIONTester Connection Specified Condition 20°C (68°F) 1 - 2 5.0 to 5.6 Ω - Connect the positive (+) battery lead with a 21 W bulb to the terminal 2 of the solenoid valve connector and the negative (-) battery lead to the terminal 1 of the solenoid valve connector for checking the solenoid valve operation.
Standard:
The solenoid makes an operating noise.
- NG: REPLACE SHIFT SOLENOID VALVE (SLT)
- OK: REPAIR OR REPLACE TRANSMISSION WIRE (See REPLACEMENT )
