AUTOMATIC TRANSAXLE DIAGNOSIS <A/T>

TSB Revision

AUTOMATIC TRANSAXLE

23C-37

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

• Malfunction of the transmission range switch sys-

tem circuit

• Damaged harness or connector

• Improper installation angle of transmission range 

switch

• Malfunction of the transmission range switch

• Malfunction of the TCM

DIAGNOSIS

STEP 1. Check the TCM terminal voltage.
[C-38 TCM connector (vehicle side, connected)]
Turn ON the ignition switch, and check by shifting to each 
range.

• "P" range: Terminal No. 6 to body ground → Battery positive 

voltage

• "R" range: Terminal No. 7 to body ground → Battery posi-

tive voltage

• "N" range: Terminal No. 21 to body ground → Battery posi-

tive voltage

• "D" range: Terminal No. 8 to body ground → Battery posi-

tive voltage

Q: Is the check result normal?

YES : Go to Step 6.
NO :  Go to Step 2.

STEP 2. Check the path between the ignition switch and 
the transmission range switch.
Turn OFF the ignition switch, and check the following items.

• Open/short circuit of wiring harness between the ignition 

switch and B-110 transmission range switch connector ter-
minal No. 3.

• Blown fuse

Q: Is the check result normal?

YES : Go to Step 3.
NO :  Repair or replace the failure section.

STEP 3. Check the wiring harness between the 
transmission range switch and TCM.
Check for continuity between B-110 transmission range switch 
terminals and C-38 TCM terminals.
NOTE: Prior to the wiring harness inspection, check the inter-
mediate connectors A-12 and A-13, and repair that if neces-
sary.

• Between B-110 terminal No. 2 and C-38 terminal No. 6: At 

the "P" range, continuity exists.

• Between B-110 terminal No. 9 and C-38 terminal No. 7: At 

the "R" range, continuity exists.

• Between B-110 terminal No. 8 and C-38 terminal No. 21: At 

the "N" range, continuity exists.

• Between B-110 terminal No. 5 and C-38 terminal No. 8: At 

the "D" range, 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 transmission range switch as a single 
unit.
Refer to 

P.23C-269

.

Q: Is the check result normal?

YES : Go to Step 5.
NO :  Go to Step 7.

STEP 5. Check the TCM connector pin terminal and the 
connection status.
Q: Is there a failure point?

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

STEP 6. 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 7. Adjust the transmission range switch.
Refer to 

P.23C-269

.

After adjustment, check the continuity between the terminals 
again.
Q: Is the check result normal?

YES : Go to Step 8.
NO :  Replace the transmission range switch.

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 :  Return to START.
