WARNING: This page is about a different car, the 2024 Toyota Camry, 2023 Toyota Camry, 2022 Toyota Camry, 2021 Toyota Camry, and 2020 Toyota Camry. However, it is still accessible from the selected car via links, so may be relevant.
- CHECK HARNESS AND CONNECTOR (4WD ECU ASSEMBLY - TRANSMISSION COUPLING ASSEMBLY)
- Disconnect the K145 4WD ECU assembly connector.
*a Front view of wire harness connector
(to 4WD ECU Assembly) - Measure the resistance according to the value(s) in the table below.
Standard Resistance
Tester Connection Condition Specified Condition K145-2 (SLC+) - K145-1 (SLC-) 20°C (68°F) 2.2 to 2.6 Ω K145-2 (SLC+) - Body ground Always 10 kΩ or higher K145-1 (SLC-) - Body ground Always 10 kΩ or higher Result
Proceed to OK NG
Result:
OK
REPLACE 4WD ECU ASSEMBLY. Refer to REMOVAL [03/2020 - 10/2020] , or refer to REMOVAL [10/2020 - ]
Result:
NG
See step 2
- Disconnect the K145 4WD ECU assembly connector.
- INSPECT TRANSMISSION COUPLING ASSEMBLY
- Disconnect the T2 4WD linear solenoid (transmission coupling assembly) connector.
*a Component without harness connected
(4WD Linear Solenoid (Transmission Coupling Assembly)) - Measure the resistance according to the value(s) in the table below.
Standard Resistance
Tester Connection Condition Specified Condition 1 (BSF) - 2 (SLC) 20°C (68°F) 2.2 to 2.6 Ω 1 (BSF) - Body ground Always 10 kΩ or higher 2 (SLC) - Body ground Always 10 kΩ or higher Result
Proceed to OK NG
Result:
OK
REPAIR OR REPLACE HARNESS OR CONNECTOR
Result:
NG
REPLACE TRANSMISSION COUPLING ASSEMBLY. Refer to REMOVAL [03/2020 - 10/2020] , or refer to REMOVAL [10/2020 - ]
- Disconnect the T2 4WD linear solenoid (transmission coupling assembly) connector.
