1. Swap Right Bleed Pressure Transducer with Left Bleed Pressure Transducer.

   1. If system checks are good, replace Right Bleed Pressure Transducer and do close out.
   2. If fault remains, continue with next step.

2. Perform wiring checks between BMC 2 and R BPT.

   1. If wiring checks are not good, repair defective wiring as required and do close out.
   2. If wiring checks are good, continue with next step.

3. Perform wiring checks between BMC 2 and JB4.

   1. If wiring checks are not good, repair defective wiring as required and do close out.
   2. If wiring checks are good, continue with next step.
      NOTE: Remove all interface components for short test.

4. Swap BMC 2 with BMC 1.

   1. If system checks are good, replace BMC 2 and do close out.
   2. If fault remains, continue with next step.

5. Replace JB4.
6. Do close out.
