## Discrepancy

DURING GARMIN SELF-TEST, NEITHER THE PILOT OR COPILOTS MSG ANNUNCIATOR ILLUMINATED. ADDITIONALLY, WHEN INDUCING A MSG GENERATING FAULT IN THE GPS, WAS UNABLE TO VIEW THE FAULT WHEN PUSHING THE MSG BUTTON ON THE #2 GPS. ALL LIGHTS WORK WHEN W/U IS HELD, BUT NOT DURING GARMIN SELF-TEST. REPLACED #2 GNS 430 IAW CMM 145MMS-023. MOC SUCCESSFULLY COMPLETED.
