San Diego Smog STAR in Chula Vista holds BAR Automotive Repair Dealer license #283817 as a STAR-certified test-only station on Main Street, authorized to perform DMV-directed inspections for gross polluters and change-of-ownership transfers. The test-only designation means the facility cannot sell repairs on the vehicles it inspects, a regulatory firewall that separates diagnosis from service and pairs with the maintenance work at Jiffy Lube Oil Change for drivers combining a smog check with routine fluid service along the same Main Street corridor. STAR certification requires the station to maintain passing scores across BAR's quarterly performance metrics, including the follow-up pass rate that tracks whether vehicles initially failed elsewhere pass after documented repairs. The 3311 Main Street bay serves used-vehicle dealers preparing inventory for resale, including lots at HS Cars Chula Vista Auto Sales that need pre-sale STAR smog clearance before titling. The analyzer platform runs OBD-II readiness-monitor checks across all supported PIDs, with catalytic-converter efficiency evaluated against mode-6 threshold data and EVAP system leak detection calibrated to 0.020-inch orifice equivalence per California's enhanced inspection protocol.
