23A-212

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 9 and A/T control relay
connector A-19X terminal 3.

NO : Repair or replace it. Refer to GROUP 00E, Harness

Connector Inspection

P.00E-2

.

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

P.00E-2

.

STEP 14. Check harness for open circuit, or short circuit to
ground between solenoid valve assembly connector B-40
terminal 5 and PCM connector C-61 <2.4L Engine> or C-63
<3.0L Engine> terminal 130.
Q: Is the harness wire in good condition?

YES : Replace the PCM.
NO : Repair it.

DTC 36: Torque Converter Clutch Solenoid Valve System

Solenoid Valve System Circuit
Refer to

P.23A-185

.

CIRCUIT OPERATION
Refer to

P.23A-185

.

DTC SET CONDITIONS
If the resistance value for a solenoid valve circuit is
greater than 3.5

Ω

for 4 seconds at 100

°

C (212

°

F) or

less than 2.6

Ω

for 4 seconds at 100

°

C (212

°

F), it is

judged that there is a short circuit or an open circuit
in the solenoid valve and the diagnostic trouble code
number "36" is displayed. The transmission is locked
into 3rd gear as a fail-safe measure, and the "N"
range light flashes once per second.

TROUBLESHOOTING HINTS (The most likely

causes for this code to be set:)

•

Malfunction of torque converter clutch solenoid
valve

•

Damaged harness, connector

•

Malfunction of the PCM

DIAGNOSIS

Required Special Tool:
MB991502: Scan Tool (MUT-II)

STEP 1. Using scan tool MB991502, read the A/T
diagnostic trouble code.

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 the data link connector.
(2) Turn the ignition switch to "ON" position.
(3) Read the A/T diagnostic trouble code.
(4) Turn the ignition switch to "LOCK" (OFF) position.

Q: Is the A/T diagnostic trouble code number "54" output?

YES : Refer to

P.23A-237

, code number 54: A/T control

relay system.

NO : Go to Step 2.

STEP 2. Using scan tool MB991502, check actuator test
item 06: Torque Converter Clutch 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 06:

Torque Converter Clutch Solenoid Valve.

•

An operation sound should be heard from solenoid
valve when the torque converter clutch 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 : 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 107 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.
