I have a 2016 Honda odyssey LX
It only has front climate control module
There is a code B1244 and B1245
Open/short rear air mix motor control
I can control everything from front. There are no controls in rear. Is this a bogus code because it is a LX trim model or is there an adapter or plug missing because there is no rear controls.
All controls in front work a/c, heater top and bottom vent control in rear of van.
Could there be a jumper plug someone removed because there are not rear climate controls.
This is a basic Honda model odyssey van-
Even on the LX trim, the Odyssey still has a rear air mix door and a rear mode door — the difference is that you don’t have a rear control panel. The front climate control module still commands the rear actuators, so the system expects to see those motors and their position feedback.
The B1244 and B1245 codes mean the front control unit isn’t seeing the rear actuators electrically. It’s not a bogus code. Usually it means one of these:
- The rear air mix or mode actuator is unplugged.
- A connector or jumper in the rear HVAC harness is missing (common after interior work).
- One of the actuators has failed internally and is “open circuit.”
The rear HVAC unit is behind the right rear interior panel. Check that both actuators are actually plugged in and that the harness hasn’t been disconnected or damaged. The LX still uses the same rear HVAC box as the higher trims; you just don’t have the rear buttons.
If all the rear vents work but the codes stay stored, one of the actuators is likely bad and not sending position feedback. Replacing the faulty actuator usually clears the codes.
