P21/P22 Delivery Test

The P21/P22 Delivery Test will check that the module is correctly plumbed to the brake chambers and test

the brake delivery air pressure. Park the vehicle on level ground and chock the wheels. During this test,

the delivery pressure should match the control pressure. After applying the brakes, the technician must

verify that the delivery and control pressures are the same. Bendix

ACom

Diagnostics system will then

release the brakes and the technician must verify that the brakes have released. The final step is for the

Bendix ACom Diagnostics software to re-apply the brakes.
