What can I do if the vehicle has a digital SWC system?
A CANBUS SWC adaptor will be required to convert the digital signals to analogue
signals.
What if the vehicle does not have any SWC functions or the SWC
function is not needed?
Insulate the key wires.
The SWC wires are connected, but when a button is pushed during
the programming procedure, there is no response from the radio
screen.
The resitance of the corresponding resistor in the steering wheel is likely too
high to be detected. If the radio is not detecting the button, disconnect the key
wires. With an Ohm meter, probe the posistive and negative SWC connections

steering wheel will need to be replaced with a lower value resistor. If there is no
reading, try probing the other positive SWC connection on the vehicle instead. If
all connections have been probed and there is still no reading when the button is
pushed, then there is a fault in the vehicle wiring. Locate and rectify the fault. If
there is a resistance reading while no buttons are being pressed, there is a fault in
the vehicle wiring. Locate and rectify the fault.
All of the SWC buttons were successfully programmed, but 1 or more
of the buttons do not work.
If 2 or more of the resistors in the steering wheel have resistance values that are

button, overwriting 1 or more of the programmed functions. If the radio is unable
to distinguish 2 or more buttons, the resistors in the steering wheel will need to be
changed to more distinct values.
