LOGIC FLOW CHARTS (Monitor Sequence)
DTC SET CONDITIONS
Check Conditions
- Voltage of battery: 2 volts or more.
Judgment Criteria
- Transmission range switch: no signal detected. (30 seconds)

OBD-II DRIVE CYCLE PATTERN
Start the engine, keep the vehicle stopped in "P," "R," "N," "D" ranges respectively for more than one minute, and turn "LOCK" (OFF) the ignition switch. Then restart the engine, and stop the vehicle in "P," "R," "N," "D" ranges respectively for more than one minute.
TROUBLESHOOTING HINTS (THE MOST LIKELY CAUSES FOR THIS CODE TO BE SET ARE:)
- Malfunction of the transmission range switch system 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 positive voltage
- "N" range: Terminal No. 21 to body ground -> Battery positive voltage
- "D" range: Terminal No. 8 to body ground -> Battery positive 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 terminal 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 intermediate connectors A-12 and A-13, and repair that if necessary.
- 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 Testing and Inspection.
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 Adjustments.
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.
