Vehicle Installation Instructions

The instructions below will guide you through the installation of the AXSWC-2 in your vehicle.

NOTE Though Metra has done extensive research, testing, and verification that the Steering Wheel Control (SWC) wires for the listed vehicles are accurate, it is the installer’s responsibility to verify that the Steering Wheel Control wires are installed correctly. If a discrepancy is found after following all instructions, please notify Technical Support.

Connections

Aftermarket Radio Harness

1. Connect Pin 6 of the AXSWC harness to the Black ground wire of the aftermarket radio.
2. Connect Pin 12 of the AXSWC to the Red accessory wire of the aftermarket radio (shown below).

Vehicle Connection(s) to Factory Harness  

1. Connect Pin 4 of the AXSWC (Green/Orange wire) to the wire in Pin 21 of the vehicle's radio harness (shown below).
2. Connect Pin 8 of the AXSWC (Black/Green wire) to the wire in Pin 22 of the vehicle’s radio harness (shown below).
3. (Optional) If a wire is present in Pin 24 of the vehicle’s radio harness:
1. Connect Pin 11 of the AXSWC (Gray/Blue wire) to the wire in Pin 24 of the vehicle’s radio harness (shown below).

TIP The connection to this wire will commonly need to be made on the factory harness side of the connector.

→→ Splicing the Steering Wheel Control Wire to the Connector

TIP At minimum, the connection point must be protected with a non-conductive tape (such as electrical tape).

Follow the steps below to splice the SWC wire into the connector wire:

1. Locate the wires entering the connector at Pin 21 and Pin 22.
1. (Optional): If a wire is present in Pin 24 of the vehicle’s radio harness:
1. Locate the wire entering the connector at Pin 24.

2. Carefully strip away a half-inch section of each wire covering using a wire stripping tool.

3. Twist the following wires around the exposed wire sections created in Step 2.
1. Pin 21: the Green/Orange SWC wire
2. Pin 22: the Black/Green SWC wire
3. (Optional): If a wire is present in Pin 24 of the vehicle’s radio harness:
1. the Gray/Blue SWC wire

NOTE Ensure the SWC wire is secured to the connector wire.

4. Secure the splice between the connector wire(s) and the SWC wire(s) with non-conductive electrical tape.

WARNING Wire color depicted does not necessarily represent the actual wire color in the vehicle.

SWC 3.5 Jack Connections

For radios with a 3.5mm port located on the rear, plug the male 3.5mm jack directly into the back of the radio.

1. Connect the 3.5mm Jack to the SWC (Steering Wheel Control) input on the back of the radio. This can be achieved through one of the methods detailed in the following sections.

Kenwood/JVC Radios with Single SWC wire

1. Connect the Blue/Yellow wire labeled  Steering Wheel Remote Input to the Brown wire of the female 3.5mm jack.
2. Plug in the male 3.5mm jack into the female 3.5mm jack.

NOTE Kenwood & JVC radios may list their SWC wire as a Marine Remote. Refer to your radio manual if you are unsure. Radios will typically auto-detect as a Kenwood, or need to be force-programmed to a Kenwood radio type (refer to Changing Radio Type below). Contact Technical Support for situations in which the above note isn’t the case.

→ Kenwood & JVC Radio Troubleshooting

If your Kenwood or JVC radio has the connector displayed below (Figure A) and you experience issues programming the SWC, please review this troubleshooting guide before contacting Technical Support.

Universal 2-Wire Radios

1. Connect the steering wheel control wire, Key-A or SWC-1, to the Brown wire of the connector.
2. Connect the remaining steering wheel control wire, Key-B or SWC-2, to the Brown/White wire of the connector.
3. The SWC (Steering Wheel Controls) functions will need to be programmed within the radio. Refer to Radios with Built-In SWC Menus below.

Universal 3-Wire Radios

1. Connect the steering wheel control wire, Key-A or SWC-1, to the Brown wire of the connector.
2. Connect the remaining steering wheel control wire, Key-B or SWC-2, to the Brown/White wire of the connector.
3. If your aftermarket radio has a KEY/SWC Ground wire, leave it disconnected and test your SWC controls.
4. (Optional) If some SWC functions do not program or function correctly, connect the KEY/SWC Ground to the radio’s ground wire.
5. The SWC (Steering Wheel Controls) functions must be programmed within the radio. Refer to Radios with Built-In SWC Menus below.

Programming the AXSWC

In order to effectively program the AXSWC, the aftermarket radio needs to be (or remain) completely wired. The AXSWC harness should be wired and the (Steering Wheel Control) SWC 3.5mm Jack or SWC wiring should be connected.

WARNING Do not plug the AXSWC harness into the interface until Step 3 below.

NOTE

If your aftermarket radio is from the Sony XAV Series, before programming to the vehicle, you must:

1. Turn the radio On.

2. From the radio's home screen, click Settings.

3. Click System.

4. In the Steering Wheel Settings section, toggle the Custom switch to Off.

5. Return to the Main Menu.

6. Power Off the radio.

You may now proceed with programming the radio to your vehicle with the steps below.

Follow the steps below to programming the AXSWC to your vehicle:

1. Open the driver’s door. Keep it open during the programming process.

2. Turn the vehicle’s ignition On.

3. Plug in the AXSWC.

4. The LED on the SWC begins rapid flashing Green and Red.

TIP Once the LED is rapidly flashing, quickly proceed to Step 6.

5. (Optional) If the LED does not turn on, refer to Connections above and ensure all steps were performed precisely.
6. The AXSWC is in Auto-Detect mode.
7. (Optional) If a Return button is present on the steering wheel:
1. Hold the Return button until the LED rapid flashing stops
2. Release the Return button and wait until the LED turns solid
1. If the LED does not turn solid, see LED Feedback below for information about how to proceed. 
3. Test the steering wheel buttons

8. (Optional) If the Green and Red flashes are missed, reset the AXSWC (as explained below) and restart the programming process from the beginning.
9. The AXSWC is being programmed into the vehicle’s steering wheel controls (SWC).

NOTE A series of seven (7) Green LED flashes identifies your vehicle type. Once the detection process completes, the Green LED will pause for one to two (1-2) seconds.

TIP Refer to Vehicle LED Feedback below for additional information about Green LED flashes.

9. The LED begins flashing Red while the interface programs itself to the aftermarket radio. A series of up to twenty-four (24) Red LED flashes identifies the detected Radio Type.

TIP Refer to Radio LED Feedback below for radio types.

10. Upon successfully programming, the LED turns solid Red.

11. Test all functions of the AXSWC installation for proper operation.

Troubleshooting

1. Verify that 12-volt power and chassis ground have a solid connection.

TIP If a ground wire is attached to the radio harness, remove it and attach it to a bolt or solid piece of metal in the vehicle dash.

2. Verify your connections are correct and that the view of the connector was established properly when locating your connections.
3. Verify the 3.5mm jack is secured in its proper location and not a secondary one.
4. Remove any aftermarket T-taps or barrel connections. These will add resistance to a resistance-based system.
5. If using a 2-wire or 3-wire universal-style radio, verify proper connection to the radio using the female 3.5 jack.
6. (Pioneer radio users) If the radio buttons are not functioning as expected or at all, attempt the following:
1. Insert and remove the 3.5mm male jack in and out of the back of the radio five to six (5-6) times.
2. On the final insertion, ensure the jack is well set.
3. Reset and reprogram the AXSWC.
7. If you’ve established all connections and the AXSWC won’t connect, remove any aftermarket connectors, T-taps, barrel connectors, and quick connectors. These will all add resistance.

WARNING Steering wheel controls must be the ones that came with the vehicle when purchased. Axxess does not support custom work to vehicles, such as adding a new steering wheel with new/different buttons.
