While on a descending grade at 55 MPH, you notice on the DP remote screen that Consist C is in a 'BV OUT' condition. Can you correct this issue, and if so, how?

While on a descending grade at 55 MPH, you notice on the DP remote screen that Consist C is in a 'BV OUT' condition. Can you correct this issue, and if so, how?

• A. No correction is possible; continue with BV OUT.
• B. Reduce the speed to below 20 mph and wait.
• C. Reboot the DP remote system.
• D. Yes. Select NORMAL from the remote display. Cut in the automatic brake valve by making at least a 10-psi brake pipe application and release.

Answer: (D)

When BV OUT appears, the brake valve signal to the DP remote has lost its normal control path. The fix is to re-establish normal brake valve operation and cut-in the automatic brake valve. Select NORMAL on the remote display to re-enable standard brake valve control. Then perform a brake pipe application of at least 10 psi and release. This action re-cuts in the automatic brake valve, restoring proper brake control for Consist C, which is especially important on a descent where reliable braking is critical. Other options don’t address reinitializing the brake valve signal or rely on unrelated steps, so they don’t resolve the BV OUT condition.
