Hi Guys

I purchased a newer model IMA battery for my car and I have the P1432 do to incompatibility. Does someone know what to do?. Thanks

What do you mean "newer model IMA battery"? As in a 2006+ model year battery? Or a new one in general?

It is my understanding that honda change some circuits in the IMA battery around the middle of 2003, which made the two versions incompatible.

Cardone refurbished batteries were universals but came with two different resistors depending of your battery model to address this problem. The battery I'm trying to install is from the second version and my IMA system is not recognizing it. The discrepancy can be resolved adding a resistor in one of the cables but I don't know the ohm value or which cable it is.

I have a hybrid repair manual around somewhere that I can check around in, but in my year of working on and around the system I don't believe I ever saw that there was a circuit change in 2003. When I bought my battery (from bumblebee batteries) it did include another MCM (Motor Control Module) that I installed, so maybe they already account for it? The batteries are the same from 03-05, using the Honda part number: 1D070-PZA-326. BUT, while looking at the MCM part numbers, only the 03 model year ECU is listed as a kit (P/N:1K080-PZA-445) while the 04/05 model year instead has the DC-DC converter (P/N:1C800-PZA-023) listed where the MCM is for the 03. This doesn't mean that those parts are necessarily different between the model years though. Looking at the ECUs shows that they did use different ones even in the same model years.

All this to say that between all model years, batteries are the same, MCMs are presumably the same, and ECUs are not the same.

From what I could find p1432 is actually a battery overheating code, not any sort of incompatibility code. I would start checking there before looking at anymore resistor stuff.

thanks for your help

yes it is something in the electronics, I have the manual too but in the manual it would not be considering the case that the battery was replaced with another one that was not yet produced.
the overheating code can be avoided adding a resistor somewhere in the circuit, to trick the computer. I just don't know where.
