WARNING: This page is about a different car, the 2022 Toyota Avalon, 2021 Toyota Avalon, 2020 Toyota Avalon, and 2019 Toyota Avalon. However, it is still accessible from the selected car via links, so may be relevant.
- CHECK HARNESS AND TRANSMISSION WIRE (TRANSMISSION WIRE (SOLENOID (SL6) VALVE) - ECM)
- Disconnect the C56 ECM connector.
- Measure the resistance according to the value(s) in the table below.
Standard Resistance
Tester Connection Condition Specified Condition C56-32 (SL6+) - C56-33 (SL6-) 20°C (68°F) 5.0 to 5.6 Ω C56-32 (SL6+) or C56-33 (SL6-) - Body ground and other terminals Always 10 kΩ or higher Result
Proceed to OK NG
Result:
NG
See step 3
Result:
OK

PERFORM REGISTRATION. Refer to REGISTRATION [04/2018 -]
- Replace the ECM.
- CHECK HARNESS AND CONNECTOR (TRANSMISSION WIRE - ECM)
- Disconnect the C52 transmission wire connector.
- Disconnect the C56 ECM connector.
- Measure the resistance according to the value(s) in the table below.
Standard Resistance
Tester Connection Condition Specified Condition C52-9 (SL6+) - C56-32 (SL6+) Always Below 1 Ω C52-8 (SL6-) - C56-33 (SL6-) Always Below 1 Ω C52-9 (SL6+) or C56-32 (SL6+) - Body ground and other terminals Always 10 kΩ or higher C52-8 (SL6-) or C56-33 (SL6-) - Body ground and other terminals Always 10 kΩ or higher Result
Proceed to OK NG
Result:
NG
REPAIR OR REPLACE HARNESS OR CONNECTOR (TRANSMISSION WIRE - ECM)
Result:
OK
See step 4
- INSPECT SOLENOID (SL6) VALVE
- Remove the solenoid (SL6) valve.
*a Component without harness connected
(Solenoid (SL6) Valve)Refer to DISASSEMBLY [04/2018 -]
- Measure the resistance according to the value(s) in the table below.
Standard Resistance
Tester Connection Condition Specified Condition Solenoid (SL6) valve connector terminal 1 - terminal 2 20°C (68°F) 5.0 to 5.6 Ω - Connect a positive (+) lead from the battery with a 21 W bulb to terminal 1 and a negative (-) lead to terminal 2 of the solenoid valve connector. Check that the valve moves and makes an operating sound.
OK
Valve moves and makes an operating sound.
Result
Proceed to OK NG
Result:
OK
REPAIR OR REPLACE TRANSMISSION WIRE. Refer to COMPONENTS [04/2018 -]
Result:
NG
REPLACE SOLENOID (SL6) VALVE. Refer to COMPONENTS [04/2018 -]
- Remove the solenoid (SL6) valve.
