Congratulations, your vehicle will be auto-detected by the
ASWC-1 Connections
1) Connect the Black wire of the ASWC-1 to chassis ground.
2) Connect the Red wire of the ASWC-1 to a 12-volt accessory wire, one that turns on
and off with the ignition key.
3) Connect the Green/Orange wire of the ASWC-1 to pin 7 of the vehicle. Below is a
picture of what the connector in the vehicle looks like:
This is the wire view of the connector in the vehicle.
NOTE: Wire colors may vary between vehicles but the pin locations remain the same.
4) Connect the Black/Green wire of the ASWC-1 to pin 8 of the vehicle.
5) Connect pin 6 of the vehicles harness to chassis ground. You may use the same chassis
ground as the black wire.
6) All other wires on the ASWC-1 please tape up, they will not be used.
Aftermarket Radio Connection
If you are using an Eclipse or Kenwood radio, plug the female 3.5mm
connector with the Brown and Brown/White wires into the male 3.5mm connector of the
ASWC-1 harness.
* For Kenwood radios or JVC’s with the Blue yellow wire: Connect the
Kenwood/JVC SWC wire (normally Blue/Yellow) to the Brown wire of the ASWC-1.
Isolate and tape the Brown/White wire, it will not be used.
**Some of the newer Kenwood radios will auto-detect as a JVC. If this is the
case, you can use a 12k ohm resistor (included) in line between the Blue/Yellow and
brown wire of the female 3.5mm jack during programming. Or you can manually
set the radio type which is in ASWC-1 manual.
* For Eclipse radios: Connect the Eclipse SWC wires (Normally Brown and
Brown/Black) to the Brown and Brown/White wires of the ASWC-1. Brown goes to
Brown and Brown/White goes to Brown/Black.
* For Parrot Asteroid Smart or Tablet: Connect the ASWC-1 male 3.5mm
jack into the AX-SWC-PARROT (sold separately) female 3.5mm jack and plug the
4 pin end into the corresponding SWC plug on the radio.
* For XITE radios: Connect the steering wheel control SWC-2 wire to the
BROWN wire of the ASWC-1. Isolate and tape up the Brown/White wire, it will not be
For all other radios, plug in the male 3.5mm connector of the ASWC-1 into the back
of the aftermarket radio, designated for an external SWC control interface. Please refer to
the aftermarket radios manual if you are in doubt where the 3.5mm connector of the
ASWC-1 goes.
Once all connections have been made, plug in the aftermarket radio if not done already.
* If this is the first time the ASWC-1 is being installed:
1) Turn the ignition on; the led will start flashing rapidly which means the ASWC-1 is
looking for the vehicle and the radio. Go to step 3.
* If the ASWC-1 was installed before:
1) Turn the ignition on; the led will flash 1 time.
2) Hold down the reset button more then 2 seconds but less then 10 seconds, the led will
start flashing rapidly.
3) The ASWC-1 will automatically find the vehicle and radio.
4) After a couple of seconds the led should stop flashing and not light up for 2 seconds.
At this point, do not push any buttons.
5) After the 2 seconds there will be a series of 7 Green flashes, some short and some
6) The led will pause for another 2 seconds then flash Red up to 15 times.
7) This is the end of the auto-detection stage. If the ASWC-1 detected the vehicle and the
radio successfully, the led will light up solid.
8) Make sure the steering wheel control buttons function correctly in the vehicle and
enjoy your radio.
So what if the led does not light up solid or the steering wheel controls do not function
properly? Check out troubleshooting section below.
Troubleshooting the Auto-Detect Mode
So you tried the auto-detect feature and at the end the led did not stay on solid, it started
flashing Red slowly, or the steering wheel controls did not function properly. That means
the ASWC-1 did not detect the vehicle or the proper radio. Follow these steps to
determine what happened:
First, some basic tips:
1) Verify that you have 12-volt accessory and a good chassis ground to the ASWC-1.
2) Verify with the vehicle information sheet on the Axxess website that you connected
the correct steering wheel control wire(s) in the vehicle to the correct wire(s) on the
3) Verify that the 3.5mm connector is connected to your radio securely and in the correct
4) If using the female 3.5mm connector on an Eclipse or Kenwood radio, verify that the
radio’s SWC wire is connected to the correct wire on the ASWC-1.
Once all the information above has been verified and correct, you will need to put the
ASWC-1 back into auto-detect mode. Follow the instructions from “If the ASWC-1 was
installed before” section above, however this time take notice of the led flashes in steps
5 and 6. Here is what the flashes stand for:
LED Feedback
The 1st series of Green led flashes represent the wire(s) that are connected to the
vehicle from the ASWC-1.
Short flashes represent the steering wheel control wire(s) that ARE NOT connected to
the vehicle.
Long flashes represent the wire(s) that ARE connected to the vehicle
1st led flash is the White/Green wire on the ASWC-1
2nd led flash is the Yellow/Green wire on the ASWC-1
3rd led flash is the Green/Orange wire on the ASWC-1
4th led flash is the Gray/Red wire on the ASWC-1
5th led flash is the Black/Green wire on the ASWC-1
6th led flash is the Gray/Blue wire on the ASWC-1
7th led flash is the Pink wire on the ASWC-1
If during the auto-detect sequence there was no long Green led flash, just short ones, the
ASWC-1 was not connected to the correct wire in the vehicle, or the incorrect wire was
used on the ASWC-1. Double check connections and the vehicle information sheet to
verify that you have the correct wires connected.
The 2nd set of Red led flashes represents what brand radio the ASWC-1 believes it
is connected to. Each flash is for a different radio manufacturer. For example if you are
installing a JVC radio, the ASWC-1 should blink Red 5 times.
1st led flash is for Eclipse
2nd led flash is for Kenwood
3rd led flash is for Clarion
4th led flash is for Sony and Dual
5th led flash is for JVC
6th led flash is for Pioneer and Jensen
7th led flash is for Alpine*
8th led flash is for Visteon
9th led flash is for Valor
10th led flash is for Clarion 5v
11th led flash is for Metra OE
12th led flash is for Eclipse type 2
13th led flash is for LG
14th led flash is for PARROT (note: AX-SWC-PARROT required (sold separately), radio
MUST be updated to rev 2.1.4 or higher and ASWC-1 MUST be updated to the latest
firmware from
15th led flash is for XITE
* Note: If the ASWC-1 flashes Red 7 times and you do not have an Alpine radio
connected to it that means that the ASWC-1 did not see any radio connected. Verify the
3.5mm connector is connected to the SWC input on the radio.
