Is there any indicator on the cx-5 that shows an under-charge condition? Or is the symptom just a dead battery?
Only a generic chsrging system (battery) light which could mean under or over charge. But you can read volts directly from the ecu and i monitored it goes from 13.2 volts to only 12 to and slightly less even at high rpm.
