Detroit Diesel

NOTE: This fault indicates the Aftertreatment Control Module (ACM) has detected a sudden temperature shift on the Diesel Particulate Filter (DPF) outlet temperature sensor. The most likely cause is an intermittent wiring concern (poor terminal fit, corrosion, chaffing, etc.). NOTE: Please see the step by step troubleshooting procedures for this specific code. NOTE: If 3246-3 or 3246-4 are active, fix those first. PROBABLE CAUSES:1. Check all wiring and connectors for the DPF outlet temperature sensor.2. DPF outlet temperature sensor.3. Inspect all harnesses and connectors between the DPF outlet temperature sensor and the ACM (Aftertreament Control Module). Detroit DD16 GHG14 (2014-16)...

DESCRIPTION:High side digital output circuit shorted to power. MONITORED PARAMETER:High sided digital output. TYPICAL ENABLING CONDITIONS:Always on MONITOR SEQUENCE:None EXECUTION FREQUENCY:Continuous when enabling conditions met. TYPICAL DURATION:2 Seconds DASH LAMPS:1. MIL2. CEL ENGINE REACTION:None VERIFICATION:Key Cycle NOTE: The supply voltage circuit is networked internal of the Aftertreatment Control Module (ACM). This circuit supplies voltage to the Coolant Valve, DEF Post Run indicator (if equipped), and the Inlet NOx sensor. A short to power on any one of those circuits will set this fault code. PROBABLE CAUSES:1. Coolant valve connector/harness.2. Failed ACM (Aftertreament Control Module). Detroit DD16 GHG14 (2014-16) Fault Code:...
