4.4.5 BIM-22-3 (Tire Pressure Monitoring System)

Dakota Digital BIM-22-3 TPMS

Type: Tire Pressure Monitoring System (TPMS)

Model: BIM-22-3

Manufacturer: Dakota Digital

Product Page: Tire Pressure Monitoring System

Manual: BIM-22-3 Manual

Overview

Wireless TPMS module displaying real-time tire pressure for all four wheels on HDX dashboard message center. Includes 4 wireless valve stem sensors.

Mounting: HDPE panel on firewall (behind dashboard)

Power: Via BIM/IO cable from HDX control box (no separate power wiring)

Specifications

  • Sensors Included: 4x wireless valve stem sensors
  • Maximum Sensors: 4 (fixed - cannot add spares)
  • Sensor Type: Dismount-to-install valve stem replacement
  • Communication: Wireless RF (sensors → BIM-22-3 receiver)
  • Display: Dashboard message center shows all 4 tire pressures
  • Programming: Sensors easily reprogrammed via Bluetooth app
  • Current Draw: TBD (powered via BIM cable)
  • Compatibility: HDX, RTX, GRFX systems (limited VFD3/VHX compatibility)

Display Integration

Dashboard Message Center:

  • Displays all 4 tire pressures simultaneously
  • Pressure units: PSI (configurable)
  • Low pressure threshold: User-configurable via Bluetooth app
  • Visual warnings for low pressure conditions

Tire Rotation:

  • Sensors remain with wheels during rotation
  • Reprogram sensor assignments via Bluetooth app after rotation
