Step	Action	YES	NO
1	Was "CVT System Check" performed?	Go to Step 2.	Go to CVT SYSTEM CHECK .
2	CVT fluid temperature sensor signal circuit check Confirm that ignition mode of keyless push start system is "OFF". Disconnect "C142", "E19" and "E20" connectors. Check for proper terminal connection to "C142", "E19" and "E20" connectors. If connections are OK, check the following points. Resistance of "A1" and "A2" circuits: less than 1 Ω Resistance between "A1" circuit terminal and each terminal at "C142" connector: infinity Voltage of "A1" and "A2" circuits: 0 - 1 V (with ignition mode of keyless push start system in "ON") Are they in good condition?	Go to Step 3.	Repair or replace defective wire harness.
3	CVT fluid temperature sensor check Check CVT fluid temperature sensor, see CVT FLUID TEMPERATURE SENSOR ON-VEHICLE INSPECTION . Are they in good condition?	Substitute a known-good TCM and recheck DTC, see TRANSMISSION CONTROL MODULE (TCM) REMOVAL AND INSTALLATION .	Replace CVT fluid temperature sensor (CVT assembly), see VALVE BODY ASSEMBLY REMOVAL AND INSTALLATION .
