Co oznacza ten kod błędu?
Although the code is titled lost communication with the hybrid powertrain control module and invalid signal, it applies to a request for speed limitation from the electric rear axle drive control module (IEM). The code is set when the engine control module has received such a request. It is set as a follow-on fault from one or more faults registered by the IEM.

- Follow-on fault from one or more faults detected by the IEM
