air con problem
Hello
Run on 5gen Prelude 2,2 vtec turbo and have a problem with AC.
S300-5143
My AC compressors clutch is still on, there is ground signal from ECU sended to the compresor clutch relay after ignition is turned on.
Doesn´t matter if the AC is on or off.
I have an adaptor harness. All pins on the harness are correct for the A/C.
On OBD1 the pin for the A/C relay is A15 and the pin for the A/C switch ia B5
On the OBD2a the A/C relay is A17 and the pin for the A/C switch ia C5
I did a double check of all cables and are OK.
With original ECU it is OK.
In SManager , in online sensors is at ACCL line still blue dot. It means something???
Thank you for help
Hopoefully you will understand my bad - Europe english

Re: air con problem
Have you tried this with a different OBD1 ECU?
Re: air con problem
No I haven´t.
Do you think use this hondata with different ECU?
It can be hardware problem?

Re: air con problem
It could be a problem with the ECU.
Re: air con problem
I took S300 out of ECU mother board and it is OK.
Also I took another P28 ECU without S300 and it is OK , there is not a ground signal from ECU sended to the compresor clutch relay after ignition is turned on.
So the problem can be be the S300???

Re: air con problem
I ordered new S300 V3 and let you know if it help.
Re: air con problem
So I bought a new Hondata S300 with clean ECU and I have a same problem like before.
But it must be a problem with my settings in calibration because If is virgin Hondata S300 installed (without my calibration downloaded) there is not a ground signal from ECU sended to the compresor clutch relay after ignition is turned on.
Can someone have a look on my calibration posted higher?
On picture below you can see my ACCL is still on.

Re: air con problem
Does the AC work with the stock ECU?
Re: air con problem
Post a datalog showing the issue.
Re: air con problem
On this picture is screenshot of problem: (ACCL is still ON, although engine is not running, but ACC button is turned off)
If I will delete all settings from Hondata, ACCL will be OFF.
If I will delete all settings from Hondata, ACCL will be OFF.

Re: air con problem
That is the calibration and not the datalog. I need to see the actual datalog not a screenshot.
Re: air con problem
Hope this is it
