Shift Solenoids

ECU Voltage Chart, Page 2connector ID:

Inspect Solenoid Resistance
- Disconnect the connector from Engine and ECT ECU.
- Measure the resistance between S1, S2, SL and body ground.

Resistance: 11 - 15 ohms

- Apply battery voltage to each terminal.
- Check that an operation noise can be heard from the solenoid.

Solenoid Inspection:

Check Solenoid Operation
- If there is foreign material in the solenoid valve, there will be no fluid control even with solenoid operation.
- Check No. 1, No. 2 and lock-up solenoid valves.
- Apply 490 kPa (5 kg/cm2, 71 psi) of compressed air, check that the solenoid valves do not leak the air.
- When battery voltage is supplied to the solenoids, check that the solenoid valves open and air flows.
