A1.0701: Trays 2, 3, and 4 Controller PCA (A23) failure
Initial Steps
1. Check all electrical connections on the Trays 2, 3, and 4 Controller PCA (A23).
Check the 3.3, 5, 12, 24, 32, and 52 Vdc LEDs on the Power Distribution PCA (A1)
1. Verify that the LEDs are lit.
Are the 3.3, 5, 12, 24, 32, and 52 Vdc LEDs on A1 lit?
No Yes
Check the 5, 24, and 32 Vdc LEDs on the Trays 2, 3, and 4 Controller PCA (A23)
1. Verify that the LEDs are lit.

1 Are the 5, 24, and 32 Vdc LEDs on A23 lit?
No Yes
1
Check the wire harness between the Trays 2, 3, and 4 Controller PCA (A23) and the Power Distribution PCA (A1)
1. Check the wire harness between A23 and A1. Repair as needed.
