DESCRIPTIONS OF MONITOR METHODS

｠

With the solenoid failure not detected and during 1st
to 4th gear driving, the switch OFF status continues
for 2 seconds. (The detection is achieved twice
during 1 driving cycle*1, and it continues for 2
driving cycles.)
*1: Indicates the series of driving cycle "ignition key
OFF → ON → drive → OFF." The "1 driving cycle,"
"2 driving cycle," and so on indicates how many
cycles are required to detect a failure.

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

｠

Malfunction of the low clutch pressure switch
system circuit

｠

Damaged harness or connector

｠

Malfunction of the TCM

｠

Malfunction of the low clutch pressure switch (valve
body assembly)

｠

Malfunction of the valve body assembly, abnormal
hydraulic circuit valve.

For the incomplete gear shifting and slippage,
first refer to the SYMPTOM CHART P.23A-23.

DIAGNOSIS

STEP 1. Check the DTC.

Q:Is the DTC other than the pressure switch set? (Is the

code other than P0841, P0846, P0871, P0876, and P0988

set?)

YES:

Check and repair the relevant DTC system.

NO:

Go to Step 2.

STEP 2. Check the TCM terminal voltage.
[C-37 TCM connector (vehicle side, connected)]
Measure the voltage between C-37 terminal No. 33 and body
ground.

｠

Low-clutch engaged: 0 V

｠

Other than above: Battery positive voltage

Q:Is the check result normal?

YES:

Go to Step 7.

NO:

Go to Step 3.

AUTOMATIC TRANSAXLE DIAGNOSIS

STEP 3. Check between the TCM connector and A/T control
solenoid valve assembly.
Check for continuity between C-37 TCM connector and B-111
A/T control solenoid valve assembly connector.

｠

Between C-37 terminal No. 33 and B-111 terminal No. 8:
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 4.

NO:

Repair or replace the failure section.

STEP 4. Check the TCM, A/T control solenoid valve
assembly connector pin terminals, and the connection
status.

Q:Is the check result normal?

YES:

Go to Step 5.

NO:

Repair or replace the failure section.

STEP 5. Check between the A/T control solenoid valve
assembly connector and low clutch pressure switch
connector.
Check for continuity between the B-111 A/T control solenoid
valve assembly connector terminals and the low clutch pressure
switch connector terminals.

｠

Between B-111 terminal No. 8 and low clutch pressure switch:
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 6.

NO:

Repair or replace the failure section.

STEP 6. Check the low clutch pressure switch body ground.
Check for continuity between the low clutch pressure switch
body and ground.

｠

Between the low clutch pressure switch body and body
ground: Continuity exists.

Q:Is the check result normal?

YES:

Replace the valve body assembly, and then go to Step

8.

NO:

Repair or replace the failure section.

STEP 7. Check the TCM, A/T control solenoid valve
assembly connector pin terminals, and the connection
status.

Q:Is the check result normal?

YES:

Go to Step 9.

NO:

Repair or replace the failure section.

STEP 8. 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:

Replace the TCM.

STEP 9. 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.

Refer to P.23A-91.

DESCRIPTIONS OF MONITOR METHODS

｠

With the solenoid failure not detected and during
2nd or 6th gear driving, the switch OFF status
continues for 2 seconds. (The detection is achieved
twice during 1 driving cycle*1, and it continues for 2
driving cycles.)
*1: Indicates the series of driving cycle "ignition key
OFF → ON → drive → OFF." The "1 driving cycle,"
"2 driving cycle," and so on indicates how many
cycles are required to detect a failure.
