DAF designs a better bus

DAF is aiming to improve flexibility and reliability with an improved CAN bus system ‘Body Builder CAN’. This reduces the number of electrical connections between the chassis and the body to just six offering benefits when it comes to service and vehicle availability.

Existing CAN bus technology combines all the electrical and electronic connections for the engine, cab, air suspension and ABS and EBS braking systems. The ‘Body Builder CAN’ sets about reducing the number of electrical connections between the chassis and the superstructure.

Reducing the number of wiring and connections also further reduces the likelihood of faults. A second factor is that the new CAN bus can be read out using DAF’s DAVIE XD diagnostic equipment. This means that DAF dealers can identify any electrical faults on the body.

The ‘CAN Extension Box’, which is programmed individually for each body, enables the addition of up to eleven switches in the cab of a DAF truck for controlling bodywork functions.

Furthermore, four switches for controlling vehicle functions can be added to the body, for instance for activating hazard warning lights or flashing beacons. The ‘Body Builder CAN’ is available on all CF and XF models.
