CONNECTIONS TO BE MADE 

(CONT)

INSTALLING THE AX-AU12-SWC

With the key in the off position:

  •  Connect the 16-pin harness with stripped leads, and either the LD-BX-AU1 or LD-BX-AU2 harness, 

into the interface. 

  •  Connect either the LD-BX-AU1 or LD-BX-AU2 harness, to the wiring harness into the vehicle.
 

Note:

 If retaining steering wheel controls, ensure the jack/wire is connected before 

proceeding onto the next step.

  •  For the steps below, the 

Red

 L.E.D. (located inside the interface, next to the potentiometer) can 

only be seen while active. The interface does not need to be opened to see the L.E.D.

  •  Turn the key (or push-to-start button) to the ignition position, the L.E.D. will turn on.
  •  Within a minute, the L.E.D. will turn off for a couple seconds, then flash slowly (up to (18) times, 

indicating which radio is connected to the interface), and then turn off. Pay close attention as 

to how many slow flashes there are. This will help in troubleshooting, if need be. Refer to the 

L.E.D. feedback section for more information.

  •  Within a few seconds the L.E.D. will turn on, and the radio will turn off.
  •  Within a minute the L.E.D. will turn off, and the radio will come back on, indicating the 

initialization process is successful.

 

Note:

  If the radio does not come back on within a minute, the interface is not communicating to 

the vehicle. Turn the key off, check all connections, and then try again. The interface may need to 

be reset at this point.

  •  If the vehicle has engine noise after installing the AX-AU12-SWC, use Axxess part 

number AX-AGL610, qty. (2) for Bose, qty. (1) for non-Bose.
