CANBUS TPMS Dashboard Car Tire Pressure Monitoring System for Fleet Telematics

CANBUS TPMS Dashboard Car Tire Pressure Monitoring System for Fleet Telematics

Most tyre pressure systems stop at their own display. This one also speaks to the vehicle. Pressure and temperature from all four wheels are streamed onto a CAN 2.0B bus in SAE J1939 frames, so the same data that appears on the dashboard screen can be read by a telematics unit, a fleet platform or an OEM head unit without any extra gateway. That single design decision is what separates an integration-grade CANBUS TPMS from a consumer kit that only shows numbers on a windscreen display.

The kit is built for buyers who are wiring tyre data into something larger: fleet managers adding pressure alarms to an existing telematics subscription, converters fitting factory-style dashboard displays, and workshops that want one screen showing four wheels instead of a phone app. Sensors are internal clamp-in units fitted inside the tyre, so they are protected from kerb damage and theft and cannot be removed without breaking the bead.

What makes this CANBUS system different

• Dual output. Local dashboard display for the driver plus CAN 2.0B output for the vehicle network, both live at the same time.
• SAE J1939 frames. Pressure, temperature, sensor ID and alarm status are mapped to standard parameter group numbers; RS232 output and custom frame mapping available on request for OEM projects.
• Four internal sensors. Clamp-in valve, 433.92MHz radio link to the receiver, sealed body rated IP67.
• Real time refresh. Data updates within seconds, with configurable high and low pressure thresholds and a high temperature alarm.
• 12V and 24V supply. Wide input range covers passenger cars, vans, light trucks and bus applications without a separate converter.
• Simple wiring. Four wires to power and CAN, no programming tool needed, no pairing procedure beyond the automatic sensor learn on first power up.

Specifications

Typical applications

• Fleet cars and vans where tyre pressure feeds an existing telematics dashboard rather than a separate app.
• Vehicle converters and upfitters building a factory-style dashboard readout into a new build.
• Rental and leasing fleets that need tyre alarms logged centrally without fitting a consumer display per car.
• Bus, coach and light commercial operators running 12V and 24V vehicles in the same yard.
• OEM and ODM projects needing custom CAN frame mapping under the buyer's own part number.

Frequently asked questions

Will this CANBUS TPMS read directly on my car's original dashboard?
Not on a standard passenger car. Factory dashboards only accept the vehicle maker's own tyre pressure messages, so a universal system cannot overwrite that screen. What this kit does is provide its own dashboard display plus a CAN output that your telematics unit or head unit can read. If the goal is the original dashboard, the practical route is an OE replacement sensor for that model instead of a separate system.

What exactly comes out of the CAN port?
Pressure, temperature, sensor position, sensor ID, battery status and alarm state, transmitted as SAE J1939 frames at 500kbps. The frame mapping document is supplied with every set, and custom mapping is possible on OEM orders so that the data lands in the parameter group your platform already parses.

Do the sensors need programming?
No. The receiver learns the four sensors automatically the first time it is powered up. Replacement sensors are learnt the same way, which keeps spares simple for fleet buyers.

Internal or external sensors, which should I order?
Internal clamp-in sensors are the right choice for cars and fleets because they sit inside the tyre, resist theft and kerb damage and last five to seven years. External screw-on sensors suit trailers and seasonal tyre changes where the sensor has to move between wheels quickly.

Can I get a sample before a production order?
Yes, one sample set is available at sample price with the frame mapping document, and OEM branding, cable length and connector type can be adjusted on production runs. Contact us with your vehicle mix and platform details for a quotation.
