Hello guys,

I have a question for you:

After replacing and ECU SET (ECU, CAS, and Key).

The vehicle starts and runs fine however the emission monitors read N/A all across. "IT IS NOT THAT THEY ARE NOT COMPLETE" None of them are AVAILABLE. Does anyone know why this is?

Your help: GREATLY APPRECIATED.

THANK YOU

if you have swapped with the correct and the same type of the DME, you should not. but if it is the case, then update the DME with the ISTAp. make sure you have the battery charger hooked up when doing it
