• Turn the ignition switch on.
• Check power supply between SSV3 E-037 terminal
B10 and ground in the A/T assembly connector
E-037.
• Battery voltage should exist.
• Or using the appropriate diagnostic test tool and a digital multimeter perform the following:
• Check the EVS3 solenoid supply voltage between TCM pin 1 and TCM pin 7 when activating the EVS3 sole-
noid and deactivating the EVS3 solenoid.
• Check the shift solenoid control signal. Check the voltage of the shift solenoid in each shift position.
• Check the voltage of the EVS3 solenoid supply circuit between the transaxle assembly electrical connector pin
B3 and pin B10.
