Lock-Up Solenoid Valve Test

LOCK-UP CONTROL SOLENOID VALVE A/B TEST

NOTE: Lock-up control solenoid valves A and B must be removed/replaced as an assembly.

1. Disconnect the connector from the lock-up control solenoid valve A/B.

2. Measure the resistance between the No.1 terminal (solenoid valve A) of the lock-up control solenoid valve connector and body ground, and between the No.2 terminal (solenoid valve B) and body ground.

STANDARD: 12 - 24 Ohms






3. Replace the lock-up control solenoid valve assembly if the resistance is out of specification.

4. If the resistance is within the standard, connect the No.1 terminal of the lock-up control solenoid valve connector to the battery positive terminal. A clicking sound should be heard. Connect the No.2 terminal to the battery positive terminal. A clicking sound should be hard. Replace the lock-up control solenoid valve assembly if no clicking sound is heard.
