STEP 13. Check the harness for an open or short circuit to
ground between A/T control solenoid valve assembly
connector C-03 (terminals 6, 7, 8 and 10) and solenoid
valve connectors C-03-4, C-03-5 and C-03-6.
Q: Is the harness wire in good condition?
YES : Replace the PCM.
NO : Replace the harness wire.

DTC 36: Torque Converter Clutch Solenoid Valve System
.
Solenoid Valve System Circuit
Refer to

.
CIRCUIT OPERATION
Refer to
.
.
DTC SET CONDITIONS
If the resistance value for the torque converter clutch
solenoid valve circuit is greater than 3.5 ohms (open)
or less than 2.6 ohms (short) for 4 seconds, DTC 36
is set. 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 are:)
• 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, check actuator test
item 06: Torque Converter Clutch Solenoid Valve.
CAUTION
To prevent damage to scan tool MB991502, always turn the
ignition switch to the "LOCK" (OFF) position before con-
necting or disconnecting scan tool MB991502.
(1) Connect scan tool MB991502 to the data link connector.
(2) Turn the ignition switch to the "ON" position.
(3) Set scan tool MB991502 to actuator test mode for item 06,
Torque Converter Clutch Solenoid Valve.
• An audible clicking or buzzing should be heard when the
torque converter clutch solenoid valve is energized.
(4) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is the solenoid valve operating properly?
YES : It can be assumed that this malfunction is intermittent.
Refer to GROUP 00, How to Use Troubleshooting/
Inspection Service Points
− How to Cope with
Intermittent Malfunctions
.
NO : Go to Step 2.

STEP 2. Using scan tool MB991502, read the A/T
diagnostic trouble code.
(1) Connect scan tool MB991502 to the data link connector.
(2) Turn the ignition switch to the "ON" position.
(3) Check for A/T diagnostic trouble code.
(4) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is DTC 54 set? (DTC 54 may be set along with multiple
DTCs.)
YES : Refer to
DTC 54: A/T Control Relay
System.
NO : Go to Step 3.
STEP 3. Using scan tool MB991502, read the A/T
diagnostic trouble code.
(1) Connect scan tool MB991502 to the data link connector.
(2) Turn the ignition switch to the "ON" position.
(3) Check for A/T diagnostic trouble code.
(4) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Are DTC 31 and DTC 35 set? (Multiple DTCs may be set.)
YES : Go to Step 8.
NO : Go to Step 4.
STEP 4. Measure the torque converter clutch solenoid
valve resistance at A/T control solenoid valve assembly
connector C-03.
(1) Disconnect connector C-03 and measure at the solenoid
valve side.
(2) Measure the resistance between solenoid valve assembly
connector C-03 terminals 7 and 10.
Resistance value: 2.7
− 3.4 ohms [at 20°C (68°F)]
Q: Is the measured resistance 2.7
− 3.4 ohms [at 20°C
(68
°F)]?
YES : Go to Step 6.
NO : Go to Step 5.

STEP 5. Measure the solenoid valve resistance at the
torque converter clutch solenoid valve connector C-03-4
inside the transmission.
(1) Disconnect solenoid valve connector C-03-4 and measure
at the solenoid valve side.
(2) Measure the resistance between torque converter clutch
solenoid valve terminals 1 and 2.
Resistance value: 2.7
− 3.4 ohms [at 20°C (68°F)]
Q: Is the measured resistance 2.7
− 3.4 ohms [at 20°C
(68
°F)?
YES : Replace the harness wire between A/T control
solenoid valve assembly connector C-03 and the
solenoid valves.
NO : Replace the torque converter clutch solenoid valve.
