multiple faults showed in dash-board

[TAM747]

my tamora’s (2004) dashboard shows multiple faults like watertemp/ fuelsensor/ oilpressure/airboxtemp. ..
BUT compared with olli’s dashboard via data-cable all IS OK.
when i reset adaptive maps and all other it’s ok for some time but after the sensor“horror“ starts again.

all sensors are new also the battery in the dash-ecu.

in the meantime my dashboard shows fault code 21 „speedometer“; if i try to adjust through "factory" nothing happens ;-(

thank you very much for input !

thank you all ;-)

the earth in the footwell is tight since one year, i just looked again this morning still tight ..

could it be same screw on the "battery"-side as well or are there other places to look for ?

thanks for advice.

thank you !

it was the inner nut opposite side footwell in the battery compartement.

the nut was about 5mm loose on the thread ..

Does this involve taking off the front wheel?

yes and the battery cover panel ..

you see the nut at the left (2 black cables) and the 2nd earth at the frame. the nut is on both sides (footwell also) a 17mm
