Shift Solenoid: Testing and Inspection

Solenoid Valves Inspection [GF4A-EL]
Inspection Of Resistance
1. Disconnect the negative battery cable.
2. Remove the air cleaner component.
3. Disconnect the solenoid valve connector.








4. Measure the resistance between terminals A through G and a ground.
ATE temperature: -40 - 160°C (-40 - 320°F)
5. If not correct, inspect the wiring harness or replace the solenoid valves, if necessary.
6. Connect the solenoid valve connector.
7. Install the air cleaner component.
8. Connect the negative battery cable.

Inspection Of Output Duty
1. Connect the SSTs (NGS) to the data link connector-2.
2. Engage the parking brake and set wheel chocks at the front and rear of the wheels.
3. Start the engine.
4. Select the "PID/DATA MONITOR AND RECORD" function on the NGS display (and press TRIGGER).
5. Select "EPC" on the NGS display and press START.
6. Depress the brake pedal firmly.
7. Shift the selector lever to D range.





8. Depress the accelerator pedal slowly and verify the duty ratio changes as shown in the figure.
9. If not as specified, inspect the powertrain control module and pressure control solenoid.
