. Leak Test
i.
Measure the tire pressure as specified in the Maintenance
Action A. If the tire is low, fill it to the recommended pressure
and take note of which tire was inflated. If the tire is low at
two consecutive PMs, contact Aperia Customer Support.
ii.
Spray a soapy water mixture over each connection point of
the hose(s) and look for bubbles that could indicate a
leak. While spraying, lightly pull and wiggle on the hoses
to ensure air is not escaping from the tire valve stem.
If bubbles form, tighten hoses and repeat. If leak persists,
complete Maintenance Action D3.
