STEP 4. Measure the low-reverse solenoid valve resistance 
at A/T control solenoid valve assembly connector B-02.

(1) Disconnect connector B-02 and measure at the solenoid 

valve side.

(2) Measure the resistance between solenoid valve assembly 

connector B-02 terminals 6 and 10.

Resistance value: 2.7 

 3.4  [at 20°C (68°F)]

Q: Is the measured resistance 2.7 

 3.4  [at 20°C (68°F)]?

YES : Go to Step 6.
NO :  Go to Step 5.

STEP 5. Measure the solenoid valve resistance at the 
low-reverse solenoid valve connector B-02-5 inside the 
transmission.

(1) Disconnect solenoid valve connector B-02-5 and measure 

at the solenoid valve side.

(2) Measure the resistance between low-reverse solenoid 

valve terminals 1 and 2.

Resistance value: 2.7 

 3.4  [at 20°C (68°F)]

Q: Is the measured resistance 2.7 

 3.4  [at 20°C (68°F)?

YES : Replace the harness wire between A/T control 

solenoid valve assembly connector B-02 and the 
solenoid valves.

NO :  Replace the low-reverse solenoid valve. Refer to
