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.

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.

DTC P0846: 2-6 Brake Pressure Switch System

M12301000419USA0000010000

PRESSURE SWITCH SYSTEM CIRCUIT
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.

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

Malfunction of the 2-6 brake pressure switch system
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, abnormal
hydraulic circuit valve.

For  the  incomplete  gear  shifting  and  slippage,

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
