Before On-Board Diagnostics

Special Tools:

INSTRUCTIONS
EEC-V 104-Pin Breakout Box allows testing of the electrical portion of the transaxle, independent of the vehicle electronics, to determine transaxle concerns.

NGS Tester allows DTC retrieval, monitoring and manual control of the transaxle.

PRELIMINARY INSPECTION
Before any diagnostic testing is done on the vehicle, some preliminary checks must be performed. Be sure to write down any results, especially DTCs retrieved, for future reference.
1. Check the ATF level and condition. Correct as necessary.
2. Visually inspect wiring harness and connectors.
3. Check for any vehicle modifications.
4. Check shift linkage for proper adjustment.
5. Verify the customer concern:
- Upshift.
- Downshift.
- Coasting.
- Engagement.
- Noise/Vibration.
6. Vehicle must be at normal operating temperature.
7. Perform vehicle OBD using NGS Tester.
8. Retrieve and record all DTCs.
9. Diagnose and repair all non-transaxle DTCs before proceeding with any transaxle diagnostics.

INSTALLATION PROCEDURES
Access the Powertrain Control Module (PCM) and connect the EEC-V 104-Pin Breakout Box. Connect NGS Tester to the Data Link Connector (DLC) and battery power.

CAUTION: Do not attempt to pry off connectors with a screwdriver. This will damage the connector and could result in transaxle concerns.
