Diagnosing Heavy-Duty Diesel Codes

Is your shop losing money swapping expensive SCR units only to have the same "SCR Performance Low" code return three days later? Onboard computers rely on sensors that have a critical engineering blind spot: they cannot distinguish between harmful NOx gases and excess Ammonia. When a DEF injector over-doses fluid ("Ammonia Slip"), the downstream NOx sensor gets overwhelmed and reports high NOx to the ECU, triggering a false SCR failure code. Bypass diagnostic guesswork and protect your shop's profitability: Bypass Computer Illusions: Directly measure true tailpipe emissions using the Kane EGA Gas Analyzer in under 90 seconds. Apply the Diagnostic Matrix: Compare live scan tool data against actual tailpipe readings. If the onboard sensor claims 400 PPM but the analyzer reads 10 PPM, the SCR is working—the sensor is overwhelmed. Prove the Repair: Use Bluetooth connectivity to generate pre- and post-repair emissions reports for fleet managers to eliminate invoice disputes and prove repair accuracy. Stop firing the "parts cannon" at false codes and verify the truth directly at the tailpipe. 🛠️ Upgrade your heavy-duty shop's diagnostic capabilities: Explore ANSED Gas Analyzers: anseddiagnostics.com Contact our technical team: info@anseddiagnostics.com #DieselTech #HeavyDutyRepair #SCRSystem #ANSEDDiagnostics #AmmoniaSlip #GasAnalyzer #FleetMaintenance #DieselMechanic #DiagnosticTools #NOxSensor
