Axxess AXDIS-TY3 Data Interface Harness with SWC 2018-up Toyota

SKU CH-FKNA-W6420

Harness provides 12-volt 10-amp accessory power, retains chimes and steering-wheel audio controls, and adds NAV outputs for select 2018-up Toyota vehicles

  • Provides 12-volt 10-amp accessory power for aftermarket radios
  • Retains Retained Accessory Power so accessories stay on after key-off
  • Supplies parking brake, reverse and speed-sense outputs for navigation
  • Keeps factory chimes audible through the new head unit
  • Maintains steering-wheel audio controls and balance/fade on non-amplified models

Vehicle-specific data interface harness

The Axxess AXDIS-TY3 connects an aftermarket radio to select 2018-up Toyota vehicles. It supplies a 12-volt 10-amp accessory power feed and retains the factory Retained Accessory Power function. The harness is designed for non-amplified audio systems only and preserves balance and fade control. Steering wheel audio controls remain operational through the interface.

NAV outputs and firmware updates

The module provides dedicated navigation outputs including parking brake, reverse and speed sense signals for compatible head units. Factory warning chimes are retained through the harness connection. A Micro-B USB port allows the interface firmware to be updated when required. These features simplify integration of multimedia navigation radios without losing factory convenience functions.

Non-amplified system limitation

The harness supports only non-amplified factory audio configurations and excludes digital amplified models. It cannot retain steering wheel controls or audio balance in vehicles equipped with factory digital amplification. Installers must verify the vehicle uses a non-amplified system before fitting this interface. Buyers needing amplified system compatibility require a different solution.

Questions about this item

Will the Micro-B USB port need a firmware update to keep steering-wheel controls working?

The interface includes a Micro-B USB port labelled updatable, so future firmware can be loaded if a vehicle update changes the CAN data.

What stops the 12-volt accessory output from running continuously on a long drive?

The accessory power is rated at 10 amps; sustained loads above that will trip the internal protection.

How much heat does the module add behind the dash during all-day use?

It draws up to 10 amps at 12 volts, so the dissipated heat stays low enough for the enclosed cavity behind the radio.
