Does the CAN bus output work when running off USB? I'm working on my bench before setting up in the vehicle and I'm having issues with CAN communication.
Also does the Hondata TCS require 120 ohm termination?
CAN bus output, 120 ohm termination
Re: CAN bus output, 120 ohm termination
No, it works whenever the traction control has power. However it will stop transmitting if it has a large number of packets which are not acknowledged.
The traction control has a termination resistor.

Re: CAN bus output, 120 ohm termination
Thanks.
I've got it working on the bench. In test mode on the TCS controller slip set to 20%, knob in position 5.
Hondata TCS Live data reads the following
Second question regarding the rear wheel speeds, how do the have the same conversion as the fronts being 8bits instead of 16 bits?

You need to test in a vehicle to get accurate packets.
Rear wheel speeds are the same as the front.
