DTC SET CONDITIONS

Check Conditions <Circuit continuity ground>

• Sport mode: 1st or Lock-up status: engaging (2nd 

to 6th).

Judgment Criteria <Circuit continuity ground>

• Lock-up and low-reverse brake linear solenoid 

valve actual current: more than 1.7 A (1 second)

Check Conditions <Circuit continuity open>

• Sport mode: 1st or Lock-up status: engaging (2nd 

to 6th).

• Lock-up and low-reverse brake linear solenoid 

valve actual command: more than 612 mA

Judgment Criteria <Circuit continuity open>

• Lock-up and low-reverse brake linear solenoid 

valve actual current: less than 190 mA. (5 sec-
onds)

.

OBD-II DRIVE CYCLE PATTERN

Drive with the sport mode (1st gear) for approxi-
mately 10 seconds, and then drive with the transmis-
sion range D, throttle valve opening 50% or less, and 
vehicle speed 60 km/h (37.3 mph) or more for 
approximately 10 seconds continuously.

.

TROUBLESHOOTING HINTS (THE MOST 
LIKELY CAUSES FOR THIS CODE TO BE 
SET ARE:)

• Malfunction of the lock-up and low-reverse brake 

linear solenoid valve system circuit

• Damaged harness or connector

• Malfunction of the TCM

• Malfunction of the lock-up and low-reverse brake 

linear solenoid valve (valve body assembly)

DIAGNOSIS

STEP 1. Check the TCM terminal voltage.
[C-37 TCM connector (vehicle side, connected)]
Measure the voltage between the terminal No. 52 and body 
ground.

• Lock-up released: 0 V

• Lock-up engaged: 300 Hz

Q: Is the check result normal?

YES : Go to Step 5.
NO :  Go to Step 2.

STEP 2. Check between the TCM connector and A/T 
control solenoid valve assembly connector.
Check for continuity between C-37 TCM connector and B-111 
A/T control solenoid valve assembly connector.
NOTE: Prior to the wiring harness inspection, check the inter-
mediate connectors A-12 and repair that if necessary.

• Between C-37 terminal No. 52 and B-111 terminal No. 4: 

Continuity exists.

When the continuity check result is OK, check that the wiring 
harness is not shorted to the body and other wiring harness.
Q: Is the check result normal?

YES : Go to Step 3.
NO :  Repair or replace the failure section.

STEP 3. Check the lock-up and low-reverse brake linear 
solenoid.
Refer to 

P.23C-275

.

Q: Is the check result normal?

YES : Go to Step 6.
NO :  Go to Step 4.

AUTOMATIC TRANSAXLE DIAGNOSIS <A/T>

AUTOMATIC TRANSAXLE

23C-76

STEP 4. Check between the A/T control solenoid valve 
assembly connector and the lock-up and low-reverse 
brake linear solenoid valve connector.
Check for continuity between the A/T control solenoid valve 
assembly connector and the lock-up and low-reverse brake lin-
ear solenoid valve connector terminals.

• Between C-111 terminal No. 4 and the lock-up and 

low-reverse brake linear solenoid valve: Continuity exists.

Q: Is the check result satisfactory?

YES : Replace the valve body assembly.
NO :  Repair or replace the failure section.

STEP 5. Check the TCM and A/T control solenoid valve 
assembly connector pin terminals and the connection 
status.
Q: Is the check result normal?

YES : Go to Step 7.
NO :  Repair or replace the failure section.

STEP 6. Check the TCM and A/T control solenoid valve 
assembly connector pin terminals and the connection 
status.
Q: Is the check result normal?

YES : Replace the TCM.
NO :  Repair or replace the failure section.

STEP 7. Erase the DTC code, and drive the vehicle for a 
while.
Check that the normal code is displayed.
Q: Is the check result normal?

YES : The procedure is complete.
NO :  Return to START.
