DESCRIPTION:This fault code sets when the Aftertreatment Control Module (ACM) detects a momentary abnormal Selective Catalyst Reduction (SCR) inlet temperature reading. MONITORED PARAMETER:Selective Catalyst Reduction Inlet temperature sensor. TYPICAL ENABLING CONDITIONS:Non-regen mode MONITOR SEQUENCE:None EXECUTION FREQUENCY:Continuous when enabling conditions met. TYPICAL DURATION:Two seconds DASH LAMPS:1. MIL2. CEL ENGINE REACTION:None VERIFICATION:SCR efficiency test. NOTE: This fault indicates that the ACM has detected a sudden temperature switch on the SCR outlet temperature sensor. Most likely cause is wiring failure. NOTE: If codes 4360-3 or 4360-4 are active, fix those first. PROBABLE CAUSES:1. Check all SCR sensor wiring for looseness, breaks, rubs, etc…2....

DESCRIPTION:Selective Catalyst Reduction (SCR) outlet temperature high. MONITORED PARAMETER:SCR outlet temperature. TYPICAL ENABLING CONDITIONS:Non regen mode. MONITOR SEQUENCE:None EXECUTION FREQUENCY:Continuous when enabling conditions met. TYPICAL DURATION:2 seconds DASH LAMPS:1. MIL2. CEL ENGINE REACTION:1. Derate 25%.2. 30 seconds shut down. VERIFICATION:SCR efficiency test. NOTE: If code 3246-15 active, fix that first. PROBABLE CAUSES:1. Inspect all connectors and wiring upstream of the ACM (SCR inlet temp, ATD harness 10-pin connector, VIH 47-pin connector, and ECM 120-pin connector).2. SCR outlet temperature sensor.3. SCR outlet temperature sensor connector/harness.

DESCRIPTION:This fault code sets when the Aftertreatment Control Module (ACM) detects that the Selective Catalyst Reduction (SCR) outlet temperature sensor reading and SCR outlet model temperature is greater than 70°C (158°F). MONITORED PARAMETER:SCR outlet temperature. TYPICAL ENABLING CONDITIONS:1. Exhaust flow greater than 600 Kg/hr.2. Coolant temperature greater than 60°C (140°F).3. Non-regen mode. MONITOR SEQUENCE:None EXECUTION FREQUENCY:Continuous when enabling conditions met. TYPICAL DURATION:2 seconds DASH LAMPS:MIL ENGINE REACTION:Derate 25% VERIFICATION:SCR efficiency test. NOTE: Monitor the DOC outlet, DPF outlet, SCR inlet, and SCR outlet temps. If they are no close together, the one that is off is the failure sensor. PROBABLE...

DESCRIPTION:This fault code sets when there is an open in the SCR outlet temperature circuit or a short to power on the SCR outlet temperature sensor signal circuit. MONITORED PARAMETER:SCR onlet temperature sensor. TYPICAL ENABLING CONDITIONS:Always enabled MONITOR SEQUENCE:None EXECUTION FREQUENCY:Always enabled TYPICAL DURATION:2 seconds DASH LAMPS:1. MIL2. CEL ENGINE REACTION:Derate 25%. VERIFICATION:Engine idle (one minute). NOTE: If code 3246-15 active, fix that first. PROBABLE CAUSES:1. Inspect all connectors and wiring upstream of the ACM (SCR inlet temp, ATD harness 10-pin connector, VIH 47-pin connector, and ECM 120-pin connector).2. SCR outlet temperature sensor.3. SCR outlet temperature sensor connector/harness.
