DTC SET CONDITIONS

Check Conditions <Stuck-off>

• Transmission range switch position: R

• Gear position: reverse

• Time after shift changing finish: 2 seconds or

more

Judgment Criteria <Stuck-off>

• Low-reverse brake pressure switch status: OFF

(2 seconds

× 2times)

Check Conditions <Stuck-on>

• Transmission range switch position: D

• Gear position: 1st, 2nd, 3rd, 4th, 5th, 6th

• Time after shift changing finish: 2 seconds or

more

Judgment Criteria <Stuck-on>

• Low-reverse brake pressure switch status: ON (2

seconds

× 2times)

.

OBD-II DRIVE CYCLE PATTERN

Reverse gear driving for 2 seconds or more

.

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

• Malfunction of the low-reverse brake pressure

switch system circuit

• Damaged harness or connector

• Malfunction of the TCM

• Malfunction of the low-reverse brake pressure

switch system (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. 43 and body
ground.

• Low-reverse 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. 43 and B-111 terminal No. 7:

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

• Between B-111 terminal No. 7 and low-reverse brake pres-

sure 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-reverse brake pressure switch
body ground.
Check for continuity between the low-reverse brake pressure
switch body and ground.

• Between the low-reverse 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.

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.
