P161A | LIN Communication Error with Alternator |
DESCRIPTION
The generator control ECU assembly and generator assembly detect reception errors respectively. The generator assembly reception error detected by the generator assembly is sent to the generator control ECU assembly via LIN communication. If an error occurs in the generator control ECU assembly or generator assembly, the generator control ECU assembly determines there is a LIN communication error and stores this DTC.
