AXTC Advanced Programming
The AXTC interface can be used in vehicles without steering wheel controls to provide retained accessory power and wires for multimedia radios (park brake/reverse / speed-sense).
Follow the steps below to program the AXTC-CH5 for just these features.
- From the 3.5mm adapter, tie the Brown and Brown/White wires together and tape up or use a connector.
- Connect the 3.5mm adapter to the 3.5mm jack from the AXTC-CH5 harness.
- Program the AXTC-CH5 per the AXTC-CH5 instructions, page 3. Disregard steps 4 and 5.
Final LED Feedback
- At the end of programming the LED light will turn solid Green which indicates programming was successful.
- If the LED light turned solid Red instead, this means programming has failed. Reset the interface and try again.
- If still no success after resetting and reprogramming the interface, refer to the Vehicle Troubleshooting document for the interface.
- Ignore the steps referencing steering wheel controls.
