The J1587 and J1939 serial data lines are used as the standard communication link for on-board vehicle instrumentation, off-board service diagnostics and fleet management.
The transmission oil temperature sensor sends a signal to the instrument cluster module which relays a signal to the engine control module (ECM) via the data link. The signal is used to demand fan activation. If the transmission oil temperature gets too high, a yellow check lamp or red stop lamp will illuminate. The engine will also derate.
