STEP 2. Using scan tool MB991502, check actuator test
item 03: Second Solenoid Valve.
(1) Connect scan tool MB991502 to the data link connector.
(2) Turn the ignition switch to "ON" position.
(3) Set scan tool MB991502 to actuator test mode for item 03,

Second Solenoid Valve.

•

An operation sound should be heard from solenoid
valve when the second 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

.

NO : Go to Step 3.

STEP 3. Check the solenoid valve output voltage at PCM
connector C-61 <2.4L Engine> or C-63 <3.0L Engine> by
backprobing.
(1) Do not disconnect connector C-61 <2.4L Engine> or C-63

<3.0L Engine>.

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

(3) Measure the voltage between terminal 106 and ground by

backprobing.

•

Voltage should be battery positive voltage.

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

Q: Is the voltage normal?

YES : Go to Step 4.
NO : Go to Step 9.
