Check Hybrid System

Check Hybrid System

These warnings can be triggered when the difference between the highest charge and lowest charge modules in pairs within the High voltage (HV) battery exceeds 1.2 volts. This can be caused by as little as one failing module in the whole HV battery, when the rest could still be going strong. So in a large percentage of electric/hybrid battery failures they are definitely worth repairing.

With many different vehicle types, we can have your hybrid vehicle up and running how it should be. Which means, improved fuel economy with the HV battery more able to support the internal combustion engine, correcting any battery related (VSC) vehicle stability control and (ABS) Anti lock braking system/(EBC) electronically controlled brake issues, plus it stops the high voltage battery cooling fan running constantly.

In the unlikely event that the battery pack is overcharged, the modules vent gases directly outside the vehicle through a vent hose
