Listen for leaks from the following components, air lines 2254, 2223, 2620, 2605, 2424, 2228, 2548, 2019,
2606, 2014, fittings, parking brake control valve, inversion valve, air bag control valve, air reservoirs, brake
relay valves, and multifunction valve.
CONDITION/INDICATION
Are air lines, fittings, valves, and/or reservoirs free of leaks?
DECISION
Air fitting(s) are leaking or loose - Tighten fitting(s). Go to (Step 6 - Does test equipment pass offset test?) to verify
problem is solved.
Air Emergency brake air line leaking - Replace emergency brake air line (WP
0073). Go to (Step 6 - Does test
equipment pass offset test?) to verify problem is solved.
Air hose(s) leaking - Replace leaking air hose(s) (WP
0067). Go to (Step 6 - Does test equipment pass offset
test?) to verify problem is solved.
Parking brake control valve leaking - Replace parking brake control valve (WP
0074). Go to (Step 6 - Does test
equipment pass offset test?) to verify problem is solved.

0081). Go to (Step 6 - Does test equipment pass
offset test?) to verify problem is solved.
Air reservoir 1 leaking - Replace air reservior 1 (WP
0068). Go to (Step 6 - Does test equipment pass offset test?)
to verify problem is solved.
