Qwerty ms frumos pt informatii. Maine o duc in service si va spun pe urma ce si cum. Dar de senzorul inteligent de pe baterie ( IBS sau ISB asa ii spune ) ce parere ai ?
Am citit pe forum ca daca ar fi eroare pe toate 4 bujii at este dus releu. Asa sa fie ?
Yes, the blue wire should be connected. That is how ECU communicates to the IBS. If IBS itself has gone bad which is located directly on the negative terminal, then the car may not start. Often, taking that blue connector out temporarily, may start the car since that stops communication between ECU and IBS. Also, if you ever need to remove IBS to change battery, be very gentle since it is sensitive to mechanical stress and changes its calibration point needed for accurate measurement of battery charge characteristics and its history.
