Troubleshooting
1.
2.
Harness Loop - The loop in the
FC-
CH21-HAR is a CAN termination resistor that needs to be
present on certain vehicles. If you have followed the instructions for cutting the loop and your
radio is not coming on and the amber LED is blinking, you may need to re-connect or cut the
loop (depending on what you did initially).
If the vehicle’s reverse lights come on when the forced reverse camera feature is engaged,
then the diode is not wired properly. Please refer to “Fig. F” on page 2 for proper diode wiring.
3.
Cannot hear uConnect or nav voice - Be sure that the 10-pin connector is plugged in behind
the
radio.
4.
If the factory radio does not come on or “flickers” off & on, the factory amplifier does not turn
on
or you are receiving audio on only one side of the vehicle, please make sure that the male
pins in
the
FC-
CH21 plug are not bent or out of place.
5.
The module can be reset to factory default settings by pressing and holding the reset button (on
the side of the module) for 5 seconds until LED1 begins blinking red. Release the button and both
LEDs will blink green indicating the module is initializing.
6.
The LEDs on the module can tell you what the
FC-
CH21 is doing. Please refer to the chart below
for LED status patterns and possible troubleshooting actions.
