This controller is located in the engine compartment. Its function is to monitor the commands sent by switches and controllers in the form of voltage. The TIPM is connected directly to the B+ cable through a pin installed on top of the controller, and it receives ground signals through connectors provided for this purpose.

The B1630 OBD2 fault code is stored because it detects that the right low beam does not meet factory specifications due to higher voltages than the allowed voltage. It makes this process after the TIPM makes checks on the right low beam.
