A Lock-up control solenoid valve assembly

B 2-P connector, View from terminal side

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

1. Disconnect lock-up control solenoid valve A and B harness connector from main harness.
2. Measure resistance between the No. 1 terminal (solenoid valve A) of the lock-up control solenoid valve connector and body earth and between the No. 2 terminal (solenoid valve B) and body earth.

Data: Resistance = 14 to 16 ohms at 25°C

3. Replace lock-up control solenoid valve assembly as necessary.
4. If the resistance is as specified, 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 heard. Replace the lock-up control solenoid valve assembly if no clicking sound is heard.

D Harness connector securing bracket

E Lock-up control solenoid valve A

F Lock-up control solenoid valve B

G Combined filter/gasket

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

1. Disconnect lock-up control solenoid valve A and B harness connector from main harness.
2. Release 2 main harness connectors from securing bracket.
3. Remove 3 bolts securing lock-up control solenoid valve assembly, remove harness connector securing bracket.
4. Remove lock-up control solenoid valves assembly, remove and discard combined filter/gasket.
5. Clean the mounting surface and the oil passages of the lock-up control solenoid valve assembly, and install a new filter/gasket.
6. Position lock-up control solenoid valve, fit and tighten bolts to 12 Nm.
7. Check the connector for rust and contamination, clean if necessary and refit connector securely.
