Shift Solenoid: Testing and Inspection

Shift Control Solenoid Valve A/B Test

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

1. Disconnect the connector from the shift control solenoid valve A/B.

NOTE: Do not remove the shift control solenoid valve A/B stay.

2. Measure the resistance between the No.1 terminal (SOL. V A) of the shift control solenoid valve connector and body ground and between the No.2 terminal (SOL. V B) and body ground.

STANDARD: 12 - 24 Ohms

3. Replace the shift control solenoid valve assembly if the resistance is out of specification.
4. Connect the No.1 terminal of the shift 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.
5. If not, check for continuity between the A/T control unit B4 or B5 harness and body ground.
6. Replace the shift control solenoid valve assembly if there is continuity between the A/T control unit B4 or B5 harness and body ground.
