The check tag antenna might have failed. Verify that the check tag
antenna is correctly positioned in relation to the transmit antenna
(see Figure 4-17 on page 4-23). Be sure that the check tag
antenna cable is securely fastened to the check tag antenna port
on the RF module.
Repeat the check tag test. If the problem persists, replace the
check tag antenna.

Verify that the check tag antenna is correctly positioned in relation
to the transmit antenna (see Figure 4-17 on page 4-23). Be sure
that the check tag antenna cable is securely fastened to the check
tag antenna port on the RF module.
Repeat the check tag test. If the problem persists, replace the
check tag antenna.

If, after moving vehicle to check for holes in the read pattern, the
problem persists, repeat the test using a different tag.
If the problem persists with a new tag, verify that the transmit and
receive antennas are correctly positioned (see Figure 4-15 on
page 4-20). Check that the antenna cables are securely
connected to the RF module.
If no problem can be found with the antennas or antenna cables,
contact the TransCore Action Center (TrAC).
