We had heavy rainfall and high tide here on long island, NY, the day before Christmas. My 02 c5z was parked on the street and was flooded, not to bad but bad enough to damage the Body Control Module and corrode the fuse box.

In the rain i pulled the seats out and sucked up all the water from the carpet and pulled all fuses and BodyCM. Proceed to spray the fuse box and BCM connectors with electrical cleaner and began to disassemble the BodyCM to asses the damage.

The BCM has corroded pins and don't see it being salvageable. The fuse box looks promising once all relays are replaced. Once i replace the replays ill diagnose further in needed.

I looked at past threads on replacement BCM programing and some of the vendors no longer offer services.

I plan on buying a working used BCM and have it programed to my RPO codes.

Can anyone recommend someone who can do this ?

I dont want to part the car out or sell it. Im adement about keeping it and enjoying it. Its a clean title, low milage Z06, it deserves to be back on the road.

Also, I don’t have access to anyone with a Tech2.

 

 

Don’t know what part of the Island you’re on but but try googling automotive computer programming…you may find someone close…good luck.

 

I have nothing local out here. Tried to google and even left a few voice mails to serveral shops.

Nothing

 

That corrosion happened in one day? Looks like it was in the ocean for a year.

 

Less then three hours.

 

UPDATE

I got the new fuse box in along with a used BCM. I did the 11 min key on and 30 seconds key off three times and got the BCM to learn the key and got the car started. Luckily the motor seems fine, i did do an oil change right after the flood anyway and witnessed no water in the oil.Now my problems are

-Steering lock stays in the LOCKED position

-Nothing in the door controls work. NO power windows, locks, memory seats.

( i do have the seats out ) would missing the seat control module cause this?

-No interior lights

Radio / HVAC and cluster all work.

I still cant track down anyone with a TECH2.

 

Looks like i need to fix this pin, does someone have access to a wire diagram to this pin ? looks to be B12. Its from the back of the interior fuse box, bottom most connector.

Anybody know where i can buy a new pin to replace it once i de-pin the harness.

 

Automotive connection pins and plugs are available all over. Amazon is one.
