FRU Codes (3545)



FRU Codes

If an error is detected by the diagnostic tests, a four-digit  FRU code is displayed. Two suspected FRU codes are shown. The two leftmost digits  indicate the first FRU code. The following table shows the FRU codes and their FRUs. The most probable failing FRU is shown first. Always start with the first FRU then continue down the list. The two rightmost digits  indicate the net FRU code. Do these FRU replacements in the same way as with the first FRU codes.

Undock the computer from the Dock I to check that the FRU code appears with the computer only. If a FRU code appears, replace the FRU by following the instructions in the Symptom-to-FRU Index for the computer being serviced. Then dock the computer on the Dock I to check if any FRU codes appear. Use the table below.
