Jeep Drive-train control module repair

[unimatrix93]

Dear forum,

My father's Jeep has this annoying rattling sound which is caused by the Drive train module as it constantly moving a solenoid.

It comes and goes as the temperature changes. For example, when you cold start the vehicle from a long parking time, it starts loudly (especially on winter) then it goes silent as the vehicle's temperature rises.

So I took the DTCM apart and found this damaged ceramic cap, which I should replace:


Now the problem is that I couldn't find the schematic for this module, nor I could identify the circuit by checking the IC next to it (TI A2C44458).

What value this SMD cap could be?

Here are some other pictures of the board:


Thank you!

Not hard to figure that out. You could make an educated guess or get a donor board, I suppose. But how you can figure this out by yourself isn't impossible and actually gets you right into the ball park.
Try to dig carefully around this damaged cap and see that you can get it off the board without any more damage.

A: this this an automotive module, so unless that MLCC in a boost converter circuit, its value rating is 25V or 50V.
B: take a set of calipers. Establish the size (length, height and width) of the damaged MLCC.
C: Download a spec sheet from a reputable MLCC manufacturer and it will tell you what capacitance that size and voltage rating has to offer. Usually there are 3 or 4 caps to choose from. Take the one with the most capacitance and you just made Bob your uncle.

Thank you very much, I will proceed to do that.
