S300 Solid Red LED
Posted: Sat Jul 11, 2015 3:21 pm
A customer brought me his S300v1 ECU and it's showing a solid red light and does not run his car properly. I connected using SManager and the settings are out of range and do not make sense. I can upload his calibration or create a new calibration but the red LED does not go out. I also tried erasing the ECU but SManager says it cannot erase it.
I tested his ECU with another S300 and it worked fine. I then put his S300 in my ECU and the same red LED came on.
I believe the S300 is bad and would like to send it in for repair. Please tell me how to proceed. Thank you.
