I have purchased an 03 battery pack to replace my unbalanced 05 hybrid battery pack. Put it in, but does not work. (I know it is good) What step am I missing?

I had to remove the battery to replace the headlight. Since then the p1600 and p1433 codes are showing up. Could disconnecting the battery cause this

So I've looked all over the web on how to install after market speakers into the rear deck of my 2005 civic hybrid, but the only instructions I can find are for regular civic sedans. The issue is that in Hybrids the IMA battery vent prevents you from folding the rear seats down to get to the deck to remove the speakers and put in new ones. I've asked so many people, starting to lose hope that it can even be done. I'm thinking you might have to remove the back seat and bench all together, but I can't even get instructions on that. If anyone has any idea on how this is done, I'd be very appreciative.

IMA replaced 7/15 IMA charge drops quickly after starting car and the charging side green lights never come on even when revving engine to 3500-4000 rpms. for the last three weeks if it dropped all I had to do was rev and it would completely charge up and keep the charge for 2 or 3 days.

Can the water pump be replaced without messing with the timing chain

Shop does't answer calls now and I don't know who to go to. The system seems to be working but it won't pass inspection because the IMA trips the service engine light. Other problem which may be related is the A/C works great until the engine shuts down at a stop then the A/C won't come back on for another day!

I have maintained my car impeccably from the day I've owned it. In the 8 years I've owned it, I've had to completely replace the whole airbag system, air conditioning system, heating system, and the IMA battery. Now the transmission went out yesterday. It isn't worth repairing anymore. This car has cost me more to operate in the 8 years I've owned it then my 08 Ford F150 I purchased in 2008. I will never own another Honda product. I've called Honda of North America and they have refused to help with any of those repairs including the IMA battery, which went out when the car had 130K miles. They argued with me for days and then finally paid for labor cost. I paid $2200 for the IMA battery, $650 for the air conditioning system and $1200 for the airbag system. Honda is terrible in customer service and paying for any repairs the government hasn't forced them to under recall.

I had the 12V battery changed last week and everything worked fine after that. Then I went back to have air bag replaced and they noticed the IMA light and engine light were on(I didn't notice it). They told me that the IMA battery needed to be replaced. (diagnosed codes P1435 and P1433) They said the car is safe to drive. So should I follow the recommendation to change the IMA battery? My mileage is only 69,900 and I purchased it for less than 5 months.

Intermittently. I replaced the alternator and it happened again. I replaced the battery and it happened again. Help??? what is wrong with this crazy thing?

Can you help me with a similar issue... My HCH 2005 rear sensors replaced by Honda 2 years ago and in the past month I got the same PO135 code for the rear sensors to be replaced, Honda verified the same and gripped with Honda not standing behind their product as the cost an arm and leg to be done by honda. Bought the Denso replacements and less than a month later, I am getting engine light on with the same replace sensor codes. Read this PCM option as a solution and a check under the hood for the . under the hood VIN J and it wasn't their. Is my HCH eligible for a PCM update? JHMES96695S000119
Any advice would help...

I've checked the fuse. I've check the deoor regulator motor by hooking up a 12 volt battery direct with lead wires, and it worked fine. I am curios if its the power switch on the door itself, but having a hard time locating one on the web?
