Headlight Control Module (ULB Control Unit), Specifications & Fitment

This is the OEM Universal Light Bar (ULB) control unit that manages the LED headlight functions on the New Cascadia. It regulates the current and switching supplied to the headlamp, controlling low beam, high beam, and daytime running lamp operation based on driver input, so it is the module to suspect when a headlight stops responding, drops a beam mode, or sets a headlamp control fault while the lamp assembly itself tests good. It is the updated control unit that supersedes the earlier 66-01405-040.

Specifications
  • Type: LED headlight control module (ULB control unit)
  • Connector: 28 pin
  • Function: Controls low beam, high beam, and daytime running lamp operation
  • Supersession: Updated unit, replaces 66-01405-040
