The BCU communicates with the instrument pack via a serial data bus.
- The instrument pack provides the BCU and IDM with details of vehicle speed.
- Signals are provided from the IDM to the instrument pack and BCU when the direction indicator lamps are active.
- For certain markets, the BCU provides a signal to the instrument pack for indicating when the transfer box is in neutral.
- The IDM can signal the instrument pack to illuminate a trailer warning lamp. This operates when the IDM senses that the current drawn by the indicator circuit exceeds a preset threshold.
- The odometer reading displayed on the instrument pack LCD screen is also stored in non volatile memory in the BCU. Whenever the ignition is turned from position I to position II, the instrument pack and the BCU compare their stored values.
- The gear selector position is displayed on the instrument pack LCD screen under the direction of the BCU.
