WARNING: This page is about a different car, the 2017 Lexus RC 350, 2016 Lexus RC 350, and 2015 Lexus RC 350. However, it is still accessible from the selected car via links, so may be relevant.
- CHECK HARNESS AND CONNECTOR (TRANSMISSION WIRE (SHIFT SOLENOID VALVE SLU) - TCM)
- Disconnect the F60 TCM connector.
*a Rear view of wire harness connector
(to TCM) - Measure the resistance according to the value(s) in the table below.
Standard Resistance
Tester Connection Condition Specified Condition F60-2 (SLU+) - F60-8 (SLU-) 20°C (68°F) 5.0 to 5.6 Ω F60-2 (SLU+) or F60-8 (SLU-) - Body ground Always 10 kΩ or higher Result
Proceed to OK NG
Result:
NG
See step 3
Result:
OK
See step 2
- Disconnect the F60 TCM connector.
- REPLACE TCM
- Replace the TCM.
Refer to COMPONENTS [09/2014 - 11/2017]

PERFORM A/T CODE REGISTRATION. Refer to REGISTRATION [09/2014 - 11/2017]
- Replace the TCM.
- CHECK HARNESS AND CONNECTOR (TRANSMISSION WIRE - TCM)
- Disconnect the F61 transmission wire connector.
- Disconnect the F60 TCM connector.
- Measure the resistance according to the value(s) in the table below.
Standard Resistance
Tester Connection Condition Specified Condition F61-13 (SLU+) - F60-2 (SLU+) Always Below 1 Ω F61-14 (SLU-) - F60-8 (SLU-) Always Below 1 Ω F61-13 (SLU+) or F60-2 (SLU+) - Body ground Always 10 kΩ or higher F61-14 (SLU-) or F60-8 (SLU-) - Body ground Always 10 kΩ or higher Result
Proceed to OK NG
Result:
NG
REPAIR OR REPLACE HARNESS OR CONNECTOR (TRANSMISSION WIRE - TCM)
Result:
OK
See step 4
- INSPECT SHIFT SOLENOID VALVE SLU
- Remove the shift solenoid valve SLU.
*a Component without harness connected
(Shift Solenoid Valve SLU)Refer to DISASSEMBLY [09/2014 - ]
- Measure the resistance according to the value(s) in the table below.
Standard Resistance
Tester Connection Condition Specified Condition Terminal 1 of the shift solenoid valve SLU - 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 2 and a negative (-) lead to terminal 1 of the solenoid valve connector. Check that the valve moves and makes an operating sound.
OK
Valve moves and makes operating sound.
Result
Proceed to OK NG
Result:
OK
REPAIR OR REPLACE TRANSMISSION WIRE. Refer to COMPONENTS [09/2014 - ]
Result:
NG
REPLACE SHIFT SOLENOID VALVE SLU. Refer to COMPONENTS [09/2014 - ]
- Remove the shift solenoid valve SLU.
