TP Dock II - FRU Codes

Applicable to: World-Wide

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.

Note:
Replace the FRUs one at a time in the sequence shown in the FRUs of the Dock II column. If a replaced part did not resolve the problem, put the original part back in the Dock II. Do not replace non-defective parts. 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 II to check that the FRU code appears with the computer only. If a FRU code appears, replace the FRU indicated in the Symptom-to-FRU Index for the computer you are servicing. Then dock the computer on the Dock II to check if any FRU codes appear. Use the table below.
