Yamae Posted August 15, 2017 Share Posted August 15, 2017 Things are a bit more complicated. In order to send accurate speed signal to the cluster, following process is done in the ABS/TRC/VSC computer monitoring and processing 4 speed signals from FL, FR, RL and RR hubs. 1, When all 4 sensors are getting signals properly, averaged RL and RR speed signal is sent. 2, When either one of rear speed sensors is not getting the signal properly, the one getting the signal is sent. 3, When both rear speed sensors are not getting the signal properly, averaged FL and FR speed signal is sent.
