Hi:

The P1600 code is usually a IMA fault, and the P1449 code is a battery deviation fault.
Both are usually early warning of some sort of hybrid battery issues.
You need to have a system tech give the hybrid system a good look over, but most likely your IMA battery pack is most likely suspect

P1600 IMA system malfunction. A P1600 code is a generic code that is set in the engine computer to tell you that there is a Hybrid system problem. In order to find out what is wrong with the Hybrid system, you will need to take the vehicle to a Honda dealer so that they can read the code in that system.
P1449 Battery module,battery module deterioration, battery module overheating, battery cell overheating. Either way you need to take the car to a Honda dealership to find out the actual cause of the P1600 and replace teh battery module

Hello there,

Apparently, from here http://www.greenhybrid.com/discuss/f50/help-p1600-p1433-28749/
This means the battery is on the way out !!!!!
and here another forum
' Okay got your answer. p1600 is generic telling you there is a manufacture specific code and that becasue of the p1433.. This code is becasue of weak batteries. You will need to plan on battaries soon. They are spendy.'

Sorry friend this is gonna cost thousands :(

I think the dealers codes.

The P1600 is a generic OBD II code. It just means that a more specific code (Honda) has been set. To find the specific code you have to take it to the dealer or have a Vetronics Mastertech scan tool to get the actual code. The P1433 indicates thats the the main battery contactor or the by-pass contactor is staying active when it should not. Using an Actron pocket code reader will only read generic OBD II codes. Hope this helps.

those codes are thrown when there is a momentary hicup in the electrical delivery from the battery pack. clear the codes and drive it, if they dont come back you are all good, it they do come back then you most likely have a corrosion issue between the battery monitor system and the battery
