Troubleshooting
1) Verifythatyouhave12-voltDContheRedaccessorywireoftheRFASWC,
usingamultimeter.
2) ReconfirmthatyouhaveagoodgroundtothesolidBlackwireoftheRFASWC.
Attention: Due to the nature of how microprocessors function, sometimes
having the ground on the RFASWC shared with the radio, and/or using the
factory ground in the vehicles wiring harness is not sufficient; and will cause
problems. Attaching the Black wire of the RFASWC to a chassis ground, solely
by itself, is highly recommended to avoid grounding issues. Ensure this wire
is straight from the RFASWC without any extensions, and make sure a ring
terminal (not supplied) is used, and crimped properly. This will alleviate any
grounding issues that may keep the RFASWC from programming; most cases of
the RFASWC not programming comes from the lack of this step being done.
3) Confirmthatthe3.5mmjackonRFASWCisconnectedtoyourradiosecurely,

Note: Some radios do not use a jack for the steering wheel controls, instead
they use a wire. If so, reference Connections to be made, and ensure that you
have the proper wire(s) connected.
