OBD-II DRIVE CYCLE PATTERN
Start the engine, and maintain the status for approxi-
mately 10 seconds. Then, turn the ignition switch
from OFF to ON, restart the engine, and then main-
tain the status for approximately 10 seconds.
.
TROUBLESHOOTING HINTS (THE MOST
LIKELY CAUSES FOR THIS CODE TO BE
SET ARE:)
• Malfunction of the line pressure linear solenoid
valve system circuit
• Damaged harness or connector
• Malfunction of the TCM
• Malfunction of the line pressure 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. 40 and body
ground.
• While driving: 300 Hz
• Other than above: 0 V
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. 40 and B-111 terminal No. 9:
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 line pressure linear solenoid.
Refer to
.
Q: Is the check result normal?

STEP 4. Check between the A/T control solenoid valve
assembly connector and the line pressure linear solenoid
valve connector.
Check for continuity between the A/T control solenoid valve
assembly connector terminals and the line pressure linear sole-
noid valve connector terminals.
• Between C-111 terminal No. 9 and line pressure linear sole-
noid 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.
