Monitor will not set

Car currently has factory setting (following stage 1 and stage 2 tune - both removed).
1- The secondary air pump has been evaluated by Subaru and a mechanic to be operational.
2 - The car has no codes showing.
3 - The computer has been reset by disconnecting the battery and we went through drive cycles to reset the ECU.
4 - All codes reset with the exception of the secondary air pump which reads incomplete.

Any suggestions on how to get the computer to read the secondary air code as complete? Some have recommended a new ECU.

Hello,

For this monitor to run you must drive the car at least fifty miles.

Please let us know what happens.

Cheers, Ken

We have driven the car several hundred miles. It will not clear the secondary air pump which reads incomplete.

Hello,

Is the engine running at temperature? Because if the engine never reaches its normal temperature the computer will never go into closed loop and run all of the monitors. Do you have a temperature gauge or light?

Best, Ken

Hello,

Yep I am starting to lean towards a bad computer that is not running the monitors. We have tried everything else.

Please let us know what happens.
