PARTS INFORMATION
SERVICE PROCEDURE:
1. Using a GDS, check for DTCs in both the "Engine" and "Automatic Transaxle" menus. Record the DTC and description.
2. From the GDS, select:
^ Vehicle

4. Disconnect the connectors at the input and output speed sensor and PCM/TCM. Check for bent pins or pins not fully inserted into the connector.
5. If a harness open/short is found, repair or replace the ECM control harness between the PCM/TCM and transaxle and go to Step 8. If not, go to Step 6.
