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.

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

• Malfunction of the high clutch linear solenoid

valve system circuit

• Damaged harness or connector

• Malfunction of the TCM

• Malfunction of the high clutch linear solenoid

valve (valve body assembly)

DIAGNOSIS

STEP 1. Check the TCM terminal voltage.
[C-38 TCM connector (vehicle side, connected)]
Measure the voltage between the terminal No. 1 and body
ground.

• High clutch engaged: 0 V

• Other than above: 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-38 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-38 terminal No. 1 and B-111 terminal No. 19:

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 high clutch linear solenoid.
Refer to

P.23C-275

.

Q: Is the check result normal?

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

STEP 4. Check between the A/T control solenoid valve
assembly connector and the high clutch linear solenoid
valve connector.
Check for continuity between the A/T control solenoid valve
assembly connector terminals and the high clutch linear sole-
noid valve connector terminals.

• Between C-111 terminal No. 19 and high clutch 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.
