Tasked to work non routine iPad write up for failing First Officer lower pitot/static system. The non-routine work history indicated the previous crew had troubleshot the cause down to the elevator feel computer. My work mate and I decided to do a test equipment test first to verify the integrity of the hoses and manifolds of the test unit. We found multiple problems with leaking hoses and a loose pitot connection.After obtaining a tight test system we performed a successful low range leak test of the lower probe. I signed off the write up as accomplished and noted the finding of bad test equipment on the sign off. I referenced the pitot/static [manuals] found on the job card that generated the non-routine.After the aborted takeoff on [date]; I was tasked with troubleshooting the First Officer airspeed indication failure; associated with the upper First Officer pitot probe. Upon removing the upper probe the quick disconnects for the pitot and 1 of 2 static lines partially engaged. Have pitot probe task cards amended to reflect the connection of the quick disconnects as an Inspection item as per [company procedure].
Technician reported unserviceable test equipment caused a misdiagnosis of a pitot/static problem and an aborted takeoff.
