The diagnostics and test procedures shall be in accordance with current technical specifications.

2.17 FAULT ISOLATION. Troubleshooting of electronic equipment and modules shall recognize the fault symptom, identify the circuit responsible, and isolate the defective component(s) or sub assembly. After a fault has been localized, but prior to corrective action, ascertain that the specific fault is actually the cause of the malfunction rather than a symptom of some other malfunction. The Contractor shall be responsive to the troubleshooting procedures as indicated in the applicable technical documentation or established test procedures.

2.18 DISASSEMBLY. The degree of disassembly on any equipment or module processed by the Contractor shall be commensurate with the level of repair required.
