Hi, I have OBD1 Honda ECU with Hondata S300 v2.
Problem: Suddenly i'm unable to log my battery voltage or not getting any input in the ECU/s300 smanager. i checked and there's 12v power supply in: - D1 pin (VBU) - A25 pin (IGP2) - B1 pin (IGP1)
i need help isolating the issue by identifying what are the + and - (ground) ecu pins that actually generates/supplies the battery voltage datalogging in the Honda OBD1 ecu. This way, i'll make that as a jumping point in my troubleshooting.
any suggestion(s) in testing & troubleshooting would be best appreciated. Thank you very much.
