INDIVIDUAL COMPONENT FUNCTION
Control module in generator controls power generation voltage by generator voltage request signal at normal running, and generator has self-diagnosis function.
COMPONENT OPERATION
Power Generation Control
ECM calculates target power generation voltage according to 12V battery condition and sends calculated value as power generation command value signal to control module in generator. When generator receives its signal, control module controls power generation voltage by its signal.
Self-Diagnosis Function
Generator transmits diagnosis result to ECM via LIN communication when detecting any malfunction. When it receives diagnosis result, ECM detects DTC and turns on charge warning light.
