Hi there, Which version of Rheingold are you using? Can you provide the VIN of the vehicle so I can walk you through to locate the test plan?
First connect the vehicle and performed a vehicle test. After the vehicle test is complete, select information search under the activities tab. Then select the function structure tab. Next, select 01 drive; then Engine control; then secondary air system, next select start search. This will pull up various test plans and wiring diagrams. Choose the "ABL" for secondary air pump; this will perform a function test for the air pump.
Hope this helps, please be sure to leave a positive rating, as this is the only way I receive credit for my work and time.
It should allow you to rate now.
What method did you use to clean the ports? How is the air volume coming out of the pump? Can you feel warm air out of the tail pipe when you run the system test and the pump is active?
The ports inside of the cylinder head need to be cleaned. This cannot be done using just a wire brush. My guess is the ports are still restricted and there isn't enough flow because of this. This is why the test is failing.
