Code P1569
Hello all,
swapped out battery packs and the code P1569 came on. I swapped them back and the code is still on. I see no cut wires or issues. I have reset the ima system, recharged the 12 volt, etc and still on. What am I doing wrong…thank you

Re: Code P1569
P1569 is Battery Cell Temperature Signal Circuit Problem
Refer to page 4:

mid way through the 2004 MY, they removed the PTC strips from the packs. Older style MCM expects to see a 20-30Ω resistance in that circuit. New style MCM expects to see nothing on that circuit.
If you have an old MCM and a new pack, update MCM or spoof it with a 20-30Ω resistor.
If you have a new MCM and an old pack, cut the circuit, so it's open.
There are other causes, but this is the most common cause when replacing a pack - MCM and battery configuration mismatch.

Shows the wire on page 3.
If old MCM, this wire should be intact and measure around 20-30Ω resistance at the connector. If this wire is cut or not present, you need to install a 20-30Ω resistor to simulate this circuit.
If new MCM, this wire should be cut or not present.
You should likely get the two packs together and compare.

Re: Code P1569
Thank you. I am thinking the batteries most likely have the red wire. So it is not just a matter of cutting them and all is well at that point? I can cut them and then put the pack back together and reset the codes?

Re: Code P1569
Please note that at no point did I indicate swapping the junction board was an option.
I have told you your two options for correcting the issue IF this is the cause. It could be something else.
The implicit 3rd option is to pay the dealership to update the MCM.

sorry if my questions are beneath your knowledge level but take a chill pill. This is a public forum and stupid or repetitive questions get asked all the time. Appreciate your help and the information you have shared.
best regards. Larry

Re: Code P1569
My level of chill is very high. I have not been upset in any way. I'm well aware of the bolded portion and the regular misspelling of names. I'm very accustomed to it. It doesn't mean I should encourage it, especially when questions are asked without any forethought or effort. The provided TSB 12-048 indicates that the junction boards are completely interchangeable (that's the purpose of the TSB - how to swap them), thus unrelated to this issue.
Good luck.
