IMA Light and P1637
 

Hi,

I just finished reconditioning the battery sticks on my 2005 Honda Civic Hybrid. Prior to starting this process I had no codes......just numerous recalibrations that I was trying to resolve.

I swapped out the 20 sticks from a different battery (after reconditioning them of course).
Upon reinstalling the IMA battery I now have the IMA light and a P1637 code.

I reconnected all the connectors.....it did not help.

Any help would be appreciated.

The battery is currently out of the vehicle.

I am checking the battery voltage at the large positive and negative terminals (where the positive and negative wires are bolted in from the car) and showing 0 volts.

Yet when I check the voltage from the first cell to the last cell I am showing 163V when the switch is on and 0 when it is off.

Pick a thread and stick with it. You're just wasting people's time.
