Default HV battery too low??

Just got a not working 09 FEH. It just won't start with the following code:



P0A7D Hybrid battery pack state of charge low
U0131 Power Steering Control Module: No Communication
U2511 CAN - Data Mis-Match (Receive data does not match expected)
U2023 Fault Received From External Node
U0111 Battery Energy Control Module: No Communication


Does it need a new HV battery or it's something else?


Thanks!

Default Re: HV battery too low??

12V is likely low/dead. Replace.

Hybrid battery is likely low.

Both can occur due to extended periods of sitting with the 12V connected.

They removed the HV jump chargers sometime in 2007, so the battery has to be jumped with a special charger at the dealership. It's also possible to remove the battery, pull the cover and charge it with a high voltage power supply, but that's not for the meek.
