Fiat Grande Punto: Blue & Me Module Detection Issues, ESM0601 Overheating, Short to Ground

Hi,

Blue & Me module. Undetectable by body. The counter flashes.
I took the disc out of the casing from the clipboard, plugged it in.
The pendrive plugged into the USB socket blinks briefly every now and then, the circuits on the board are getting warm, but one - ESM0601 - is getting very warm.
I checked the legs and the 3 closest to the cut corner have a short to ground.
The layout is attached.
I can't find a description of this layout anywhere.
Maybe someone has already had contact with the Blue & Me module and maybe repaired it?
Attached photos of the plate on both sides.

When the counter is flashing, it means that it sees something in the network but is as if unpaired.
Do a proxy alignment and it should be ok and the counter will stop blinking confirming that all modules in the network are paired.

Moderated By tzok:

... or that he cannot see something that he had paired (scrambled).

Hi. Thanks for the answer.

I know that if the counter is flashing "something is missing". I'll try to do the alignment. Maybe he will see the module.
If not, I have to find some capable electronics to check these elements.
The question about the chip remains valid: if someone has a datasheet for this system, he could check with his B&M if these 3 pins have a short to ground.

Plug it in again. Very often, this driver most likely freezes. When reconnected, he recovers his life.

These switchboards are a garbage can, they fell as flies, is dead and that's why the meter is flashing because the CAN is incomplete, it is this element that is heating up is a standard, I did not repair this carcass, but I am curious if it is enough to replace this chip.

Disconnecting and reconnecting does nothing. Disconnecting the "-" clamp, removing the fuse.

How you searched for this datasheet

The chip inlet should revive the module if it is damaged.

But there is no datasheet for ESM0601 there. There are other models but I haven't found it there. Or I'm blind ;-)

Well, let's try today. I just wonder what the module is and whether anything can be done without it ...

I will be at home for a computer. I looked and in some link it was just to theog.

Cool. I will be very grateful.

Friend, you were right, the website referred me to a completely different system with the same number of feet.

It looks like an audio power amplifier.

Today I desolder these capacitors and check them with a tester. I will let you know the effects.
If necessary, they are not expensive, so when I desolder and turn out to be good, I will buy new ones and solder new ones. It won't be worse

Buddy, and any progress in the resuscitation of this module?

Hello, I have a similar problem when the Blue & Me unit discharges the car battery. Did replacing the chip help someone: SM0601? Mobile Bluetooth does not see this control unit.

Pin 3 reads like it is short to ground but it is not. Pin 3 is the current sense for the boost FET (IRF7484Q) on the back of the board. There is a 0.2 Ohm resistor between the source and ground, this is what people are reading and thinking it is a short.

I have one here and I think these boards have booted but are sleeping/hung. I have both 5V rails and the 4 outputs from the ESM0601 are all present - 3.3V, 2.75V, 1.8V and 1.4V. The 32kHz reference clock is there, the ARM is warm and I think it is running code - there is activity on the bus. The boost circuit is not running but I don't think that is an issue, I think it just hasn't got that far in the boot sequence.

I suspect it is waiting to speak to the vehicle but can't. I have seen CANBUS transceivers go back in vehicle modules before so I will run down that rabbit hole next.

Did anyone get theirs sorted?
