Please follow the steps below to test the connection and ACC signal:
•
Connect the USB port of the hardware kit to the power outlet of the main device
(DC/IN). Start the engine and wait for the main device to turn on. If the main
device fails to power on, press and hold the power button to manually turn it on.
If the message “Connect to an external power source” is sh
own, check the power
cable of the hardware kit to see if it is correctly connected to the regular electric
fuse.
•
After the main device has turned on, turn off the engine and remove the key.
Check if the main device powers off or enters sleep mode. For some cars, the
ACC power off signal will only be triggered when the driver seat door is opened
after the engine is turned off. Some car models will only trigger the ACC power
off signal after the engine has been turned off for a certain period of time. For
such cars, observe for some time after the ACC power is turned off to check if the
main device powers off or enters sleep mode.
•
After the main device powers off or enters sleep mode, restart the engine and
check if the main device automatically turns on.
The above steps show that the connection is correct and that the ACC signal can be
triggered correctly.
If the connection or ACC signal test fails, please check the wiring of the hardware kit and
ensure that the fuse and ground are correctly connected. If the connection is correct,
but the test fails, contact the after-sales service for assistance.
After ensuring that the connection and ACC signal are correct, go to the next step
–

management.
Step 4: Cable management
Route the hardware kit to the location of the main device. If the hardware kit is too long,
tie it up, but do not cut it. Cutting the hardware kit will affect the power and ACC signal
to the main device.
