Renault Trafic 2011 Dash problem-ABS block

[saint_84]

Hi,
I have problem with new Trafic, I remove dash from car read 93C76 put in the car,and speedo dont working(compleatly dead).
In forum, read about Can block from ABS unit.
And now I dont know how remove this problem.
Must read ABS module or change something in dash?
I dont have possibility to read faults or change via OBD SMOK tool ;/

I will add that, the counter has not been changed.(only saved original dump).

Guys please help me ;(

If you only read eeprom should work, check connections.

Have you changed something?

[saint_84]

Thank You for fast respond,
No, I dont change eeprom (only desolder and read)

Then I put him back in car and nothing hapend black,no reaction like power off or something.
I check all 2 times 93c76 soldering connection etc..maybe is blocked?

[saint_84]

Its possible that reaction when 93c76 epprom is corupted?
I read him via UPA USB and all working without problems,then i solder him back and put in car.

no need for any can blockers etc , its a simple eprom only job, put original dump back in make sure all is ok and start again from scratch

I this moment I read epprom again and ther is nothing changed all working.
In 5min I check in car with this dash connector.
I've never seen such a situation,no reaction like power cut or something...
OK I check and reaply

[saint_84]

Ok, Im back
Good news car starts without problems,engine work normaly,but dash not working.

I dont know where to search,I disconnect battery,reconnect all connectors.
Sick strange situation...
Maybe this is some goldpin soldering prolem?
or PCB soldered connections fault?

Guys where searching?

take eeprom out and check connetions, maybe you broke one

[saint_84]

I take it out 3 times all legs are ok.
Use hot air and/or UPA with pomona soic clip.
20min ago i checked upa reads without problem eeprom are ok nothing changed.
Beside of 93c76 is big controller like motorolla with many legs,maybe when I take out all plastic covers soldered legs in pcb broke?

I change km in many of cars but in my life Ive never seen
such thing.

The funny thing,is that my car!!

look if you have solder eprom with pin 1 in good position.

[saint_84]

VAGERIC
Thats idea,but checked

I thinking,maybe in first time I was so stupid and solder ic,upside down and in second time I solder it upside-result the same with no luck.

I give up, this french-german sh** win

Tommorow or maybe today I resolder all connections in dash PCB plate,now I must go to client without clocks.

[vageric]

try with a new eprom 93c76!

[saint_84]

PROBLEM SOLVED!
I buy used Dash and change eeprom with old one from defective speedo,and works perfectly.

And I still do not know the cause of counter corruption
situation one in a million.

Thanks guys for help!

Good to hear that you have solved the problem.

Are you using ESD protection during the work?
