Battery Light

[Blessed987]

so i just checked the app checked all the sensors and its showing the o2 sensor b is pulling 4v since its a narrowband it should only be 1v max right ? its disabled in the kpro and i dont have a engine light so i'm going to remove the pins/wires as you suggested and im guessing that will fix my issue. the eld sensor is showing between 2.95v and 3.30v so does that sounds correct ? appreciate the help!

so i moved the two wires as recommend by hondata but still having the battery draining issue. can you tell me what the correct voltage ranges for the secondary o2 sensor and eld numbers are or if the info i posted is correct or no ? thanks

There is not a set voltage, and it is not pulling any voltage, it is ouptuting and detecting a voltage.

What pins exactly did you move?

so i got the battery light off by switching to a PRB Kpro ecu instead of the PNF Kpro, now the temperature gauge doesn't work at all and the air conditioning doesn't work with the PRB. when i switch back to the PNF kpro ac and temperature guage works but the battery light stays on. cars runs fine on both ecus no error codes.

i found a post where someone had the same problem with ac and temperature guage not working and they changed the multiplexer setting and it started working so can you tell me the correct multiplexer setting to use fo the d17a2 ?

[Spunkster]

Are you uploading the same calibration to both these ECU's?

[Blessed987]

no different calibration two different ecus. so the issue im having with both ecus is when i disable the multiplexor my ac and temp guage do not work. i can select the option to use vtec pressure switch input for ac control but thats make my ac stay on all the time. when i set the multiplexor to normal the battery light comes on and stays on and drains my battery, what should i do '?

[Spunkster]

The multiplexor setting should be set to normal. VTEC pressure switch should be unchecked.

[Blessed987]

yes i have the multiplexor set to normal but battery light stays on is that normal? alternator is charging and everything works with normal setting, ac and temperature gauge work so i will just live with the battery light as the only way to get it off is to disable the multiplexer but then the ac and temp gauge dont work. Thanks

[Spunkster]

It sounds like you have something wired incorrectly in the car.

[Blessed987]

the car is 100% stock, any idea where to check or what it could be ? thanks

[Blessed987]

i only started having this issue when i got kpro, with the factory ecu i dont have these problems

[Spunkster]

Where are you getting the calibration you are using?

[Blessed987]

from the kmanager program

[Spunkster]

Tell me step by step exactly how you are opening the calibration.

Post the calibration that you are using for each of these ECUs.
