I noticed a problem with the car that Start/Stop is not working and normally this indicate some issues like low voltage etc however I have no errors lights on the cluster.

I decided to scan the car and found out 8 errors.
u0010, U0140, U0073, U0140, U0121, U0151, U0159, U0131

After Reset the car voltages look normal:
Engine Running : 14.5v idle, 14.3v on Load.
Engine off : 12.6v
Ac voltage : 0V
Voltage drop is normal.

The car is working fine with Start/Stop disabled that is the only symptom, Any idea please on how I can try to remove these errors?

Thanks

Visit Autofthings to review headlight uv protection in case you concern.

Have you try to reset PCM to clear the codes and check the battery voltage?

This issue was from a faulty ELM327.

Tested with New Elm327, reset PCM and everything is working fine.

Thanks
Steve
