Preliminary Inspections

Before any diagnostic testing is done on a vehicle, some preliminary checks must be performed as follows. Be sure to note findings, especially any DTCs found, for future reference.
- Check fluid level and condition of the transaxle.
- Check for add-on items (phones, computers, CB radio, etc.).
- Visually inspect wiring harness and connectors.
- Check for vehicle modifications.
- Verify the shift linkage is properly adjusted.
- Verify customer concern:
- upshift, downshift, coasting, engagement, noise/vibration
- Vehicle must be at normal operating temperature.
- Perform vehicle On-Board Diagnostic.
- Record all DTCs.
- Service all non-transaxle codes.
