CAN bus interfaces

How do I retrofit parking sensors on a CAN bus vehicle?

A CAN bus interface lets retrofit parking sensors switch on and off correctly by reading gear and road speed from the vehicle bus, arming the sensors at low speed and muting them once you drive away.

Fitting aftermarket parking sensors to a modern vehicle used to mean finding a reverse-light feed and an ignition wire. On a CAN bus vehicle those simple wires are harder to find, and cutting into the loom is best avoided. A CAN interface solves it by reading the signals the sensor kit needs directly from the bus.

Arming and muting at the right time

Good parking sensor behaviour is about timing. The sensors should be active when you are manoeuvring and silent once you drive off. The interface reads road speed and gear position from the vehicle bus, so it can arm the sensors below a set speed and mute them above it. Rear sensors can follow reverse gear, and front sensors can be brought in at low speed and then muted as you pull away.

Choosing the unit

For a rear-only fit, the CAN KONTROL PARK REAR reads reverse gear off the bus. For front sensors that need speed-based muting, the CAN KONTROL PARK FRONT handles the low-speed arm and drive-away mute. Where you want both ends managed together, the CAN KONTROL PARK DUAL covers front and rear from one module.

All three are built on the i2CAN platform, designed and manufactured in the UK by Intellitec, part of Scorpion Group. One configurable platform covers the range, set up to the vehicle and the sensor kit rather than swapped for a different box each time.

What to tell us

Tell us the make, model and year, whether you are fitting front, rear or both, and the sensor kit you are using. We confirm the right unit and configure the arm and mute behaviour for the vehicle.

Frequently asked questions

Why do retrofit parking sensors need a CAN interface?
Aftermarket sensor kits need to know when to switch on. On a CAN bus vehicle there is no simple wire to tap, so the interface reads gear and speed off the bus and drives the sensor kit at the right time.
Will the sensors switch off when I drive away?
That is the point of reading road speed. The interface can arm the sensors below a set speed and mute them above it, so they are active for manoeuvring and quiet once you are moving.
Front, rear or both?
There are units for rear only, front only, and dual front and rear. Tell us the layout you are fitting and we confirm the right unit and configuration for the vehicle.
Does it work on vehicles under warranty?
Yes. On vehicles under warranty the unit can read the bus with a no-cut inductive reader, so the native wiring is left intact.
