STEERING WHEEL CONTROL NOTES & EXCEPTIONS

The illustrations of steering wheel controls and buttons in this manual are “typical”.
The actual controls and placement of the controls varies between each make, model,
trim level, and/or options package. The overall operation and characteristics are
similar between makes. If you experience difficulty with operation or the information
provided in this manual, please call our Toll-free Tech support line [phone]
Ext. 3 or visit our website for other support options including “Live” chat and email:

www.scosche.com.

For Volume UP/DOWN operation, pressing either button once will increase or decrease
ONE small increment. Press and hold for continuous UP or DOWN volume adjustment.

For CD Seek UP/DOWN operation, pressing either button once will skip UP or DOWN
tracks. Press and hold for manual track FWD/RR.

The radio seek UP/DOWN operation varies between stereo brands. In some cases
pressing the seek UP/DOWN button once will skip UP or DOWN to the next strong
radio station. In other cases, this button will select through Memory preset stations
on the stereo. Consult the steering wheel control pages for your particular brand and
configuration.

TROUBLESHOOTING

Stereo will not respond to Factory steering controls:

Verify vehicle compatibility. Check the S3-1 harness instruction for your particular
vehicle listing.

Verify / Check installation:

1. Check connections at S3-1 module, verify power, ground is present.

2. Check to determine if steering wheel control module is properly connected to
main S3-1 module.

3. Check to determine if steering wheel OUTPUT wire or 3.5mm cable is
connected to the correct steering wheel INPUT at the back of the aftermarket
stereo.

4. Check to determine that steering wheel selection potentiometer is set to
matching brand of aftermarket radio i.e. A: Alpine, C: Clarion, J: JVC,
K: Kenwood, P: Pioneer, S: Sony (see page 3)

connecting additional +12V switched accessories to this output source as
it may cause damage to the S3-1 module itself. If 10A output is not
sufficient, then a relay is needed (Relay not included).

The following steps are provided as a general guide. For specific information for your
vehicle, consult the instructions supplied with your vehicle-specific S3-1 harnness
(sold separately).

1. Disconnect the negative battery cable from the battery to avoid short circuits.

2. Remove and unplug factory stereo. (If needed, call Scosche Toll-free Tech for
assistance with radio removal: [phone] Ext. 3)

3. Match and connect the Power/ground wires from the S3-1 Vehicle specific
harness to the wires provided with your stereo. The color codes on the Scosche
harness are designed to match most aftermarket stereos.

• Take note that some of the wires for your new stereo come from the S3-1
interface box itself and not the vehicle connectors.

4a. The S3-1 speaker connections are pre-terminated with RCA jacks for installations
requiring Line input: Toyota JBL, GM Standard Bose and Ford Premium sound.

4b. If your vehicle does not have a Bose or Premium system, cut off the RCAs
and wire the speaker leads directly to the speaker wires from the new stereo.

4c. All FORD harnesses must have RCAs cut on vehicle side of circuit board.

5. Tape any unused wiring to prevent short circuit.

7. Reconnect the negative battery cable**.

** For GM vehicles, alternate power up (initialization steps) are required.
See General Motors specific notes section.

8. As you install your new stereo, place the S3-1 module(s) and harnesses in the rear
of the dash cavity behind the stereo.

OPTIONAL: Cable ties or double-sided tape can be used to secure the module, but
are not included.

GENERAL MOTORS INSTALLATION NOTES

HOW TO TEST FOR “PREMIUM BOSE” SYSTEMS

There are two types of Bose systems available in some models of GM vehicles. The
S3-1 interface is not compatible with the Digital Premium BOSE (y91/z75 systems) To
test for digital Bose systems, tur n the factory radio volume up and down rapidly. If the
sound system reacts immediately then the system is a Standard Bose, not a Premium
Bose. If there’s a slight delay in the system as you turn it up and down quickly, then this
vehicle may have Premium BOSE. Note: you may also check the service parts code
sticker usually located in the glove box for “y91” or “z75” equipment codes.

S3-1 GENERAL MOTORS INTEGRATED SAFETY & WARNING CHIMES

When replacing the factory stereo in your GM vehicle, the S3-1 interface will replace
portions of your vehicle’s audible SAFETY and WARNING CHIME systems. If the stereo
is removed without the proper accessory these functions of your vehicle will be LOST
including: Your vehicle’s ECM (Electronics Control Module) will also store an error code if
operated without the factory radio installed and you may experience difficulty in having
the vehicle serviced at the dealership. The Scosche S3-1 will send the proper data
commands to your vehicle’s ECM (Electronics Control Module) to indicate a “healthy”
status for diagnostic purposes.

WARNING & SAFETY CHIMES LIST:

• Parking assist • Seatbelt warning chime

• Lights left on reminder • Check engine/service indicator

• Turn signal click • Key left in ignition reminder

• Low fuel

POWER UP (Initialization procedure)

In order to ensure the proper functionality of the S3-1’s +12V RED Accessory wire, we
recommend that the following procedure be followed; in sequence.

1. Disconnect the Scosche Interface from the vehicle radio harness.

2. Close all doors and hood, Turn off all lights and remove the keys from the ignition.

3. Wait 3 to 4 minutes (without opening a door, turning on a light, inserting keys,etc.).

4. Connect the Scosche Interface to the vehicle’s radio harness and start vehicle.

5. Test interface for functionality.

STEERING WHEEL MODULE

STEERING WHEEL MODULE SETUP

The Scosche S3-1 offers “plug and play” steering wheel control setup. No complicated
learning, programming or splicing wires is required. Setup can be completed in just
seconds! (Tool is provided by Scosche.)

1. Break off the small flat blade
adjustment driver from the
side of the steering wheel
module housing as shown in
illustration.

2. Carefully click the selector (arrow)
dial to the correct letter that
corresponds with the brand of
aftermarket stereo you are installing:

A=ALPINE, C=CLARION, J=JVC,

K=KENWOOD, P=PIONEER, S=SONY

3. Connect the steering wheel control module harness to the Main S3-1
interface via the 10-Pin connector. (This step not shown)

4. Plug the 3.5mm connector into the “Remote” jack on the back of your
aftermarket stereo. For Kenwood, connect the Blue wire to the remote
control input wire of the radio. (This step not shown)
