NOTE: The common powertrain controller (CPC) digital outputs have the same SPN as some motor control module (MCM) faults. NOTE: If any battery voltage codes present, first those first. If code 625-9 active, fix that before proceding as well. PROBABLE CAUSES:1. CPC recently programmed incorrectly.2. Another computer on the truck is the cause of the problems (ABS, Transmission, etc…).

DESCRIPTION:Idle speed out of range. MONITORED PARAMETER:Engine rpm TYPICAL ENABLING CONDITIONS:Engine rpm = idle. MONITOR SEQUENCE:None EXECUTION FREQUENCY:Continuous when enabling conditions met. TYPICAL DURATION:10 seconds DASH LAMPS:MIL VERIFICATION:Engine Idle: One minute. PROBABLE CAUSES:1. If any camshaft or crankshaft codes, fix those first.2. If any throttle or idle validation switch codes, fix those next.3. Injector failure.

DESCRIPTION:This fault code sets when the engine speed is above 2500 rpm. MONITORED PARAMETER:Engine speed TYPICAL ENABLING CONDITIONS:Engine speed greater than idle. MONITOR SEQUENCE:None EXECUTION FREQUENCY:Continuous when enabling conditions met. TYPICAL DURATION:Two seconds DASH LAMPS:MIL ENGINE REACTION:Engine brakes are activated. VERIFICATION:Start and run the engine. POSSIBLE CAUSES:1. Vehicle was driven downhill in too low of a gear or without using the engine brakes.2. Vehicle equipped with a DT12 transmission driven downhill with the engine brakes set on high.3. Crankshaft speed sensor fault.4. External combustible fluids drawn into the air intake. NOTE: This fault code can be induced by the driver...
