STEP 8. Measure the supply voltage at A/T control 
solenoid valve assembly connector B-40.
(1)  Disconnect solenoid valve assembly harness connector 

B-40.

(2) Turn the ignition switch to the "ON" position.

(3) Measure the voltage between harness connector B-40 

terminal 9 and ground.

• The voltage should equal battery positive voltage.

(4) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is the measured voltage battery positive voltage?

YES : Go to Step 11.
NO :  Go to Step 9.

STEP 9. Check A/T control relay connector A-17X in the 
engine component relay box and A/T control solenoid 
valve assembly connector B-40 for loose, corroded or 
damaged terminals, or terminals pushed back in the 
connector.
Q: Are the connectors and terminals in good condition?

YES : Go to Step 10.
