Problem: The OBD socket pin is powered normally, and the connection is Mercury M072 Cable, but the OBDSTAR iScan Pro Volvo tablet cannot communicate with the ECM.
Here are the operation steps, where did I go wrong?
Recommended Solution
- Verify the cable:
Try replacing the M072 cable with the M086 cable;
- Test on Different Models:
If the issue persists, proceed to test the communication on other compatible Volvo marine engines. Select models such as:
KAD-300
KAD-44
TAMD-74
TAMD-75
Testing across different models helps determine if the problem is isolated to a specific ECM or is a more general communication issue.
Conclusion
By systematically checking the diagnostic cable and verifying functionality across multiple engine models, you can effectively isolate the cause of the communication failure between your OBDSTAR iScan Marine Scanner and the ECM. This method ensures a professional and efficient troubleshooting process.
