STE/ICE:Diagnostic and test equipment used to troubleshoot at unit maintenance level. It isused to make measurements and find faulty parts in the carrier system.4. VERIFY NO FAULTSFOUND:After you have completed the corrective action, you must verify that no faults exist.If the fault condition still exists, then the fault is not fixed or there is another fault.If this happens, start at the beginning of the correct/appropriate troubleshootingprocedure until you find and correct all faults.
