STEP 8. Using scan tool MB991502, check actuator test
item 04: Overdrive Solenoid Valve.

CAUTION

To prevent damage to scan tool MB991502, always turn the
ignition switch to "LOCK" (OFF) position before
connecting or disconnecting scan tool MB991502.
(1) Connect scan tool MB991502 to data link connector.
(2) Turn the ignition switch to "ON" position.
(3) Set scan tool MB991502 to the actuator test mode for item

04: Overdrive Solenoid Valve.

•

An operation sound should be heard from solenoid
valve when the overdrive solenoid valve is operated.

(4) Turn the ignition switch to "LOCK" (OFF) position.

Q: Is the solenoid valve operating properly?

YES : This malfunction can be intermittent. Refer to GROUP

00, How to Use Troubleshooting/Inspection Service
Points

−

How to Cope with Intermittent Malfunction

P.00-6

.

NO : Replace the PCM.

STEP 9. Check connector B-40 at solenoid valve assembly
for damage.
Q: Is the connector in good condition?

YES : Go to Step 10.
NO : Repair or replace it. Refer to GROUP 00E, Harness

STEP 10. Check the overdrive solenoid valve at solenoid
valve assembly connector B-40.
(1) Disconnect connector B-40 and measure at the solenoid

valve side.

(2) Measure the resistance between terminal 5 and 9.

Standard value: 2.7 - 3.4

Ω

Q: Is the resistance at the standard value?

YES : Go to Step 11.
NO : Replace the overdrive solenoid valve. Refer to

GROUP 23B, Valve Body

P.23B-69

.

STEP 11. Check the power supply voltage at solenoid
valve assembly connector B-40.
(1) Disconnect connector B-40 and measure at the harness

side.

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

(3) Measure the voltage between terminal 9 and ground.

•

Voltage should be battery positive voltage.

(4) Turn the ignition switch to "LOCK" (OFF) position.

Q: Is the voltage normal?

YES : Go to Step 13.
NO : Go to Step 12.
