REV. 11/6/2018 INSTAX-HYKIA4-SWC
With the key in the off position:
1. Connect the
16-pin harness with stripped leads
, and the
AX-HYKIA4-SWC harness
, to the
AX-
HYKIA4-SWC interface
.
2.
Connect the
AX-HYKIA-SPDIF interface
to the 14-pin connector from the
HYKIA4-SWC harness
.
Attention! Do not connect the
AX-HYKIA4-SWC harness
to the wiring harness in the vehicle just yet
.
Attention! If retaining steering wheel controls, ensure that the jack/wire is connected to the
radio before proceeding. If this step is skipped, the
AX-HYKIA4-SWC interface
will need to be
reset for the steering wheel controls to function.
For the steps below, the L.E.D. located inside the AX-HYKIA4-SWC interface can only be seen
while active. The interface does not need to be opened to see the L.E.D.
1. Start the vehicle.
2. Connect the
AX-HYKIA4-SWC harness
to the wiring harness in the vehicle.
3. The L.E.D. will initially turn on solid Green, then turn off for a few seconds while it auto
detects the radio installed.
4. The L.E.D. will then flash Red up to (18) times indicating which radio is connected to the
interface, and then turn off for a couple of seconds. Pay close attention to how many red
flashes there are. This will help in troubleshooting, if need be. Refer to the L.E.D. feedback
section for more information.
1. With the vehicle and radio turned on, turn the volume up 3/4 of the way.
2. With a small flat-blade screwdriver, adjust the potentiometer clockwise to raise the audio
level; counter clockwise to lower the audio level.
3. Once at a desired level, audio adjustment is complete.
5. After a couple seconds the L.E.D. will turn on solid Red while the interface auto detects the
vehicle. The radio will shut off at this point. This process should take 5 to 30 seconds.
6. Once the vehicle has been auto detected by the interface, the L.E.D. will turn on solid Green,
and the radio will come back on, indicating programming was successful.
7. Cycle the key off, then back on. If the driver’s door is closed, open and close the door.
8. Test all functions of the installation for proper operation, before reassembling the dash.
9. If the interface fails to function, refer to the Troubleshooting section.
Note: The L.E.D. will turn on solid Green for a moment, and then turn off under normal
operation after the key has been cycled.
