Mac Pro: Apple Hardware Test error messages

Symptoms

When testing Mac Pro quad-core or 8-core computers using Apple Hardware Test (AHT) diagnostics, you may encounter diagnostic flags signaling the computer does not pass when the reading is actually acceptable.

Apple Hardware Test may display one of these error messages:

4 SNS/1/40000001:ICAC-3.222*

or


4 SNS/1/40000001:ICBC-3.222*

*3.222 is a value; this value varies.

Resolution

For this test, a reading of 1.000 to 4.000 can be considered as passing even though the diagnostic flags it as not passing. A value below 1.000 should still be treated as not passing. In this case, contact your local Apple Service Provider.
