For 1990-2009 cars

1. Inspect the solenoids (S1, S2, SN).
2. Check the resistance between the terminal and solenoid body with an ohmmeter.

Specifications

• | S1, S2 11-15Ω (20°C)

• | Neutral Sol SN 12-16Ω (20°C)

3. Apply battery voltage (12V) to the solenoid. At this time, check that an operation noise can be heard from the solenoid.
4. Inspect the lock up control solenoid (SLU) and the pressure control solenoid (SLT).
5. Check the resistance between the terminal and the terminal with an ohmmeter.

Specifications

• | SLU 5.0-5.6Ω (20°C)

• | SLT 3.3-3.7Ω (20°C)
