Troubleshooting Guide
Working on a new or unlisted vehicle?
We are always looking for new vehicle information. If you’ve successfully completed the installation on a vehicle with
steering wheel controls, and the vehicle is not listed in these instructions or on our Website, contact us at
[email protected] so that we may add the information to the instructions.

My Vehicle is not listed in the Identification and Connection Chart:
• Please visit

for the most up to date listing of compatible
vehicles.
No power / won’t go into programming mode:
• Check
Red
wire connection and fuse. Make sure INTERFACE is connected to sw12 volts, not co12 volts.
• Make sure vehicle ignition is on.
The INTERFACE controls the stereo immediately without pressing any buttons on the steering wheel:
• During programming, press the buttons on the steering wheel firmly UNTIL the left LED turns off. Releasing the button too early
will cause the INTERFACE to send out a signal even when no buttons are pressed.
I am using Version # , 8, 9 or and the LED goes out after I push the program button and before I push a SWC button:
• Remove any resistors connected to the White INTERFACE wire and ground; then try the program button again.
• If voltage on the INTERFACE's White wire is LESS THAN 4.60v with the key on you need to visit
http://www.pac-audio.com/
bulletins/swicalculator.htm
. Here you will find a SWI Calculator. When measuring SWC resistance the INTERFACE's White
wire cannot be connected to the vehicle.
• Detach the White Interface wire from the vehicle. Does the LED now stay on when the program button is now pressed?
• If YES: Visit
http://www.pac-audio.com/bulletins/swicalculator.htm
and use the SWI Calculator.
• if NO: The interface needs to be replaced.
The radio changes when the key is off (RAP mode pertaining to GM vehicles) or does not work when the car/truck is running:
• The INTERFACE's Red accessory wire needs to be connected to the same circuit as the radio. If you are using a radio
replacement interface that does not supply BATTERY voltage as the ACC. circuit, a relay need to be installed as follows:
• Terminal 86 to supplied ACC wire, Terminal 85 to Gnd Terminal 30 to the INTERFACE Red wire and Terminal 87 to BATTERY.
I cannot program the INTERFACE version number:
• Is the radio selection switch in position "0"? If so refer to page 5 and select a radio position before attempting to program a
version number.
When programming the SWC buttons, it takes seconds for the light to go out and it never comes back on:
• Do the connection instructions say to connect another vehicle wire to ACC voltage or chassis ground? If so, test the circuit with a
Digital Multi Meter (the factory radio must be plugged in) and verify that the factory radio is providing the same output.
The INTERFACE controls the radio whenever the steering wheel is turned (mostly late 80’s early 90’s Honda/Acura):
• Program the INTERFACE for version #11.
