B1634 CHRYSLER, DODGE, JEEP, RAM: LEFT HIGH BEAM CONTROL CIRCUIT HIGH
The TIPM (Totally Integrated Power Module) is a controller that works as an intelligent fuse box for most of the vehicle’s electrical system. Its purpose is to observe the commands of several modules and switches, which are provided in the form of voltage. The Totally Integrated Power Module is located in the engine compartment near the battery. It is connected directly to the B+ cable through a bolt located on the top of the controller, and it is grounded by electrical connectors. It has internal relays, fuses, and a microprocessor that perform tasks commanded by the FCM.
The OBDII diagnostic code B1634 for Chrysler, Dodge, Jeep, and RAM vehicles is related to the left high beam. It is set when the TIPM detects that the left high beam does not meet the factory specifications due to high voltage.
