AUTOMATIC TRANSAXLE DIAGNOSIS <A/T>

TSB Revision

AUTOMATIC TRANSAXLE

23C-101

.

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.

.

DTC SET CONDITIONS

Check Conditions <Stuck-off>

• Transmission range switch position: D

• Gear position: 2nd, 6th

• Time after shift changing finish: 2 seconds or

more

Judgment Criteria <Stuck-off>

• 2-6 brake pressure switch status: OFF (2 sec-

onds

× 2times)

Check Conditions <Stuck-on>

• Transmission range switch position: D or R

• Gear position: 1st, 3rd, 4th, 5th, reverse

• Time after shift changing finish: 2 seconds or

more

Judgment Criteria <Stuck-on>

• 2-6 brake pressure switch status: ON (2 seconds

× 2times)

.

OBD-II DRIVE CYCLE PATTERN

Drive in 2nd and 6th gears for 2 seconds or more.

.

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

• Malfunction of the 2-6 brake pressure switch sys-

tem circuit

• Damaged harness or connector

• Malfunction of the TCM

• Malfunction of the 2-6 brake pressure switch

(valve body assembly)

• Malfunction of the valve body assembly, abnor-

mal hydraulic circuit valve.

CAUTION

For the incomplete gear shifting and slippage,
first refer to the SYMPTOM CHART

P.23C-28

.

DIAGNOSIS

STEP 1. Check the DTC.
Q: Is the DTC other than the pressure switch set? (Is the

code other than P0846, 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. 44 and body
ground.

• 2-6 brake engaged: 0 V

• Other than above: Battery positive voltage

Q: Is the check result normal?

YES : Go to Step 3.
NO : Go to Step 7.

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.
NOTE: Prior to the wiring harness inspection, check the inter-
mediate connectors A-12 and repair that if necessary.

• Between C-37 terminal No. 44 and B-111 terminal No. 10:

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 2-6 brake pressure switch
connector.
Check for continuity between the B-111 A/T control solenoid
valve assembly connector terminals and 2-6 brake pressure
switch connector terminals.

• Between B-111 terminal No. 10 and 2-6 brake 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 2-6 brake pressure switch body ground.
Check for continuity between the 2-6 brake pressure switch
body and ground.

• Between the 2-6 brake 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.
