Welcome to the Ultimate Freightliner & Detroit Diesel Fault Code Guide
This page acts as a comprehensive diagnostic reference for GHG14, EPA10, and EPA07 emissions standards. We have compiled detailed lists of SPN (Suspect Parameter Number) and FMI (Failure Mode Identifier) codes for the:
- ACM (Aftertreatment Control Module)
- MCM (Motor Control Module)
- CPC (Common Powertrain Controller)
Pro Tip:
Since this list is extensive, the fastest way to find your code is to press Ctrl + F (on Windows) or Command + F (on Mac) and type your SPN number into the search bar.
Section 1: How to Find Your Fault Codes (Dashboard Method)
Before you can fix the problem, you need the SPN (Suspect Parameter Number) and FMI (Failure Mode Identifier). You don't always need a scanner; you can often read them directly from the dashboard.
Method A: Newer Freightliner Cascadia (Digital Dash)
- Park the truck and set the parking brake. Turn the key to the ON position (engine off).
- Use the Steering Wheel Controls (+ / - buttons).
- Scroll until you see "Park Menu" or the Wrench Icon on the screen.
- Select "Diagnostics" and press Enter (OK).
- Select "Fault Codes" or "Active Faults".
- The screen will display the SPN and FMI (e.g.,
SPN 3216 FMI 13).
Note: It may also show the module (ACM, MCM, CPC).
Method B: Older Cascadia & M2 Business Class (Standard Dash)
- Turn the key to ON.
- Locate the Mode/Reset buttons on the dash (often to the right of the steering wheel).
- Press and hold Mode until the display changes to "Diag" or "Faults".
- Press Mode again to cycle through codes.
- Codes often flash in a sequence: SYS (System) → SPN → FMI.
Section 2: The "Color Codes" (Dashboard Warning Lamps)
In the GHG14 ACM2.1 system, "color codes" refer to the severity of the dashboard lamps. The color tells you how urgent the repair is.
Section 3: Common Fault Codes (GHG14 ACM2.1)
1. ACM (Aftertreatment Control Module)
Controls the DPF, DEF, and SCR systems.
- SPN 3216 / 3226: Inlet/Outlet NOx Sensor Drift/Failure.
- SPN 3364: Improper DEF Quality.
- SPN 3719: Soot Level High (Regen required).
- SPN 4364: SCR NOx Efficiency Low.
2. MCM (Motor Control Module)
Controls the engine block, fuel, and air.
- SPN 100: Engine Oil Pressure Low.
- SPN 110: Coolant Temperature High.
- SPN 636: Crankshaft Position Sensor.
- SPN 651-656: Injector Cylinder Faults.
3. CPC (Common Powertrain Controller)
Controls throttle, speed, and communication.
- SPN 84: Vehicle Speed Sensor.
- SPN 91: Accelerator Pedal Position.
- SPN 168: Battery Voltage High/Low.
Section 4: Next Steps for Repair
Is the Red Lamp (RSL) Active?
Do not drive. Check vital fluids (Oil, Coolant). If levels are fine, it is likely a sensor failure or mechanical blockage. Tow recommended.
Is the Amber Lamp Active?
- Perform a Parked Regen if the DPF light is on.
- Check DEF Fluid: Ensure it is topped up and not contaminated.
- Check Battery: Weak batteries cause "Ghost Codes".
