STEP 8. Using scan tool MB991502, check actuator test
item 01: Low-Reverse 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
01: Low-Reverse Solenoid Valve.
•
An operation sound should be heard from solenoid
valve when the low-reverse 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
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
Connector Inspection
.

STEP 10. Check the low-reverse 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 6 and 10.
Standard value: 2.7 - 3.4
Ω
Q: Is the resistance at the standard value?
YES : Go to Step 11.
NO : Replace the low-reverse solenoid valve. Refer to
GROUP 23B, Valve Body
.
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 10 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.

STEP 12. Check connector A-19X at A/T control relay for
damage.
Q: Is the connector in good condition?
YES : Repair it because of harness open circuit or short
circuit to ground between solenoid valve assembly
connector B-40 terminal 10 and A/T control relay
connector A-19X terminal 3.
NO : Repair or replace it. Refer to GROUP 00E, Harness
Connector Inspection
.
STEP 13. Check connectors C-61 <2.4L Engine> or C-63
<3.0L Engine> at PCM connector for damage.
Q: Are the connectors in good condition?
YES : Go to Step 14.
NO : Repair or replace it. Refer to GROUP 00E, Harness
Connector Inspection
.
STEP 14. Check harness for open circuit, or short circuit to
ground between solenoid valve assembly connector B-40
terminal 6 and PCM connector C-61 <2.4L Engine> or C-63
<3.0L Engine> terminal 129.
Q: Is the harness wire in good condition?
YES : Replace the PCM.
NO : Repair it.
