DESCRIPTIONS OF MONITOR METHODS

• With the ignition switch ON, an abnormal signal 

combination is detected for 2 seconds.

.

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

• Malfunction of the shift switch assembly system 

circuit

• Damaged harness or connector

• Malfunction of the TCM

• Malfunction of the select switch

• Malfunction of the Shift switch (up)

• Malfunction of the Shift switch (down)

DIAGNOSIS

STEP 1. Check the TCM terminal voltage.
[C-37 TCM connector (vehicle side, connected)]
Measure the voltage between the TCM connector terminals 
and body ground.

• Ignition switch: ON

• Between C-37 terminal No. 36 and body ground

Sport mode selected: 1 V or less
Other than above: battery positive voltage

• Between C-37 terminal No. 35 and body ground

Shift switch (up) operated: 1V or less
Other than above: battery positive voltage

• Between C-37 terminal No. 46 and body ground

Shift switch (down) operated: 1 V or less
Other than above: battery positive voltage

Q: Is the check result normal?

YES : Go to Step 2.
NO :  Go to Step 3.

STEP 2. Check the TCM connector, vehicle-side wiring 
harness connector pin terminal, and the connection 
status.
Q: Is the check result normal?

YES : Go to Step 9.
NO :  Repair or replace the failure section.

STEP 3. Check between the TCM connector and the select 
switch.
Check for continuity between the C-37 TCM connector and the 
C-24 select switch.
NOTE: Prior to the wiring harness inspection, check the inter-
mediate connectors C-33 and repair that if necessary.

• Between C-37 terminal No. 36 and C-24 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 between the shift switch assembly and 
body ground.
Check for continuity between the C-24 shift switch assembly 
(ground) and body ground.

• Between C-24 terminal No. 7 and body ground: Continuity 

exists.

Q: Is the check result normal?

YES : Go to Step 5.
NO :  Repair or replace the failure section.

STEP 5. Check between the TCM connector and the shift 
switch (up).
Check for continuity between the C-37 TCM connector and the 
shift switch (up).

• Between C-37 terminal No. 35 and C-24 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 6.
NO :  Repair or replace the failure section.

STEP 6. Check between the TCM connector and the shift 
switch (down).
Check for continuity between the C-37 TCM connector and the 
shift switch (down).

• Between C-37 terminal No. 46 and C-24 terminal No. 9:   

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 7.
NO :  Repair or replace the failure section.

STEP 7. Check the shift switch assembly as a single unit.
Refer to 

P.23C-284

.

Q: Is the check result normal?

YES : Go to Step 8.
NO :  Repair or replace the failure section.

STEP 8. Check the TCM, vehicle-side wiring harness 
connector pin terminal, and the connection status.
Q: Is the check result normal?

YES : Replace the TCM.
NO :  Repair or replace the failure section.

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.
