Tech Tips

The battery ECU assembly, battery voltage sensor (for upper side) and battery voltage sensor (for lower side) cannot be checked due to the installation condition. As a result, in some cases the voltage and waveform cannot be checked for some parts. Voltages and waveforms are indicated for reference only.
