Appendix F: Troubleshooting Guide
No power / won’t go into programming mode:
• Check
Red
wire connection and fuse. Make sure INTERFACE is connected to switched 12V+.
• Make sure vehicle ignition is on.
Won’t program radio commands:
• Make sure version number and IR Extended mode setting are programmed before attempting to program radio commands. The
right LED of the INTERFACE will flash the programmed version number when power is applied.
Steering wheel controls won’t operate new head unit
• Make sure you have programmed the correct version number and IR Extended mode setting.
• Make sure you’ve followed the programming instructions precisely, noting each exception and time sequence. Repeat if neces-
sary.
• Place the INTERFACE emitter within range of the new head unit.
To replace a broken IR emitter:
•
Replace with standard IR emitter (i.e. Radio Shack part number 276-143). Long lead of IR emitter goes to INTERFACE’s emitter
Red
wire and short lead goes to INTERFACE’s black wire)
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.
During programming, the right LED turns off and goes to the left LED without pressing a button on the wireless remote:
• Turn off fluorescent droplights or shop lights during programming.
• Make sure the INTERFACE’s IR LED is not in direct sunlight.
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.
When pressing and holding down the volume button on the steering wheel, the volume or track on the radio only goes up or
down by one or is very slow. May also relate to other functions.
• Depending on some vehicles, some stereos may not respond very well. Try programming the interface for ‘Extended IR Mode’.
This may or may not help in response from the stereo.
For mostly GM vehicles, when going into radio programming the left LED turns off and goes to the right LED without press-
ing the steering wheel buttons.
• If the SWC wire in the vehicle’s steering wheel column is cut in half, do not cut the brown loop wire on the interface.
