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
.
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
.
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.
