The car is Honda Accord 2003 coupe with V6 engine and above 150,000 miles

I need help me. I have been using this car for quite sometimes now after i bought it 3 months ago (as Nigerian used) and I discovered that the instrument cluster is having issue.

Some of the gauges in the instrument cluster is not working fine. For instance, the speedometer, the RPM gauge and the temperature gauges are not working well. But the fuel gauge is working very well. The failing gauges only work when I turned ignition to ON and after few seconds they went off and remain off (except the fuel gauge) until when next I put off the car and turn again.

I have also used a working instrument cluster I removed from another similar car but still did not work.

I have called experts to help scan the car but unfortunately the ECU can not connect with the car scanner.

Please help, how can I get the ECU to work with the scanner machine?

Secondly what do you think is wrong with the those gauges why they are not working.

Can sensors be responsible for failing gauges?

Sensors like speed sensors etc.

I don't know much but I love to learn more so that I can advise my mechanic on what to do?

Try another ECU

How Sir. I think the ECU is the port under the dashboard where car scanner is plugged. Is there any other ECU ?

I need your contributions guys

ECU means brain box Sir. He mean you should test another brain box in your car to see if the guages on your instrument cluster will wotk

OK Sir.

Is this why car scanner couldn't work or scan the car?

Of course if the ECU is faulty there might be no communication whatsoever

What about the failing gauges that work and stop ?

Ok

That's not the ECU...the ECU is what they call the brain box in local parlance

ECU is the brainbox

I have had this same Experience on my Honda Accord 08 v6 Evil spirit

There are two things most likely involved

1.) Like otheres have suggested you might have to use another ECU to test and see.

2. It might be the immobilizer unit I think, during my own time a guy from Oyingbo which is like Honda village in Lagos came and changed those things , they are around the steering side, and the computer connected with the car,

I'm 100% sure if you try both if this options you would solve your problem or be close to solving it

Thank you very much... I will try these two options
