This test will confirm if power is applied to the source.

If the output switch is not on, disconnect the electrical

connector from the lift axle valve and manually

apply 12 VDC to determine if the problem indicates

electrical wiring or the TLV-9000

2 - MANUAL (NON-SOFTWARE) METHOD OF TESTING

VALVE OPERATION

1. Block the vehicles wheels and fully charge the tractor

and trailer air system. The trailer must not be loaded

for this test.

2. Apply the vehicle parking brakes.

3. With the wiring harness disconnected from the

TLV-9000 lift axle valve, disconnect both air lines

from the lift bag delivery ports (Ports 23) and install

test plugs into the fittings. Apply a soap solution around

the opening of the exhaust port and check for leakage.

Leakage must not exceed a one (1) inch bubble in less

than five (5) seconds around the exhaust seal.

4. Remove the test plugs and reconnect both air lines back

to the lift bag delivery ports (Ports 23). Apply power

(12 VDC) via a separate power supply to the TLV-9000

valve. The lift axle must rise to the desired position.

5. With the lift axle in the raised position, disconnect both

air lines from the suspension bag delivery ports (Ports

21) and install test plugs into the fittings. Apply a soap

solution around the opening of the exhaust port and

check for leakage. Leakage must not exceed a one

(1) inch bubble in less than five (5) seconds around the

exhaust seal.

6. Remove the test plugs and reconnect both lines back

to the suspension bag delivery ports (Ports 21). Turn

off the power to the TLV-9000 lift axle valve. The lift

axle should return to its original position.

If the valve does not function as described; or if leakage is

excessive, replace the valve.
