TC2 - Check Solenoid Electrical Operation



- Key "ON", engine "OFF".

- Disconnect transmission connector.

- Using a mirror, inspect both ends of the connector for damaged or pushed out pins, corrosion, loose wires, etc. Service as necessary.

- Refer to the schematic. TC - Testing Schematic

- Connect an Analog Volt/Ohm Meter (VOM) or a Digital Volt/Ohm Meter (DVOM) positive test lead to VPWR circuit and negative test lead to solenoid circuit of the transmission vehicle harness connector.

- VOM/DVOM on 20 volt scale.

- While observing VOM/DVOM, depress and release throttle several times to cycle solenoid output "ON" and "OFF".

- Does the suspect solenoid output voltage change at least 0.5 volt?

Yes -- Reconnect connector. Refer to Transmission and Drivetrain.

No -- Remove jumper wire. Go to TC3. TC3 - Check Continuity of Solenoid Signal and VPWR Harness
