STEP 1. Check the TCM terminal voltage and frequency.
STEP 2. Check the power supply and sensor ground.
STEP 3. Check for continuity in PGA1 line between the input shaft speed sensor connector and TCM connector.
STEP 4. Check the path between the battery and the input shaft speed sensor.
STEP 5. After replacing the input shaft speed sensor, drive the vehicle for a while, and then check the DTC again.
STEP 6. Check for continuity in PGA- line between the input shaft speed sensor connector and TCM connector.
STEP 7. Check the TCM connector pin terminal and the connection status.
Is there a failure point?
Repair or replace the failure section. Replace the TCM.
STEP 8. Drive the vehicle for a while.
Check that the normal code is displayed.Is the check result normal?
The procedure is complete. Replace the TCM.
STEP 9. DTC recheck.
