B1135 engine switch/electric motor switch and C1776 Acc system fail detected.

[Dirk-Jan Kuijt]

Hi all,

Tried to search the forum for possible solutions to my problem(s) but couldn't find a suitable one yet.

I've got both faultcodes on my obd reader and they can't be reset.
Also the car seems to only use the electric motors, when the engine runs it still misses power.

Got the fault after a DC charging session. Got the obd reader out and noticed low (aux) battery voltage so immediately changed the battery but that didn't solve the problem.
Also the display shows; ev system service required/electrical system service required/acc system service required...

Hopefully somebody has suggestions...

Edit: B1135 motor switch was indeed the motor switch. Inside the switch, it holds a rubber membrane type spring of which one was not working. Replaced the switch and gone the fault code. Remaining the ACC failure though...
