Summary
This article supersedes TSB 17-0068 to update the Service Procedure and Parts List. Some 2016-2017 F-650/F-750 vehicles equipped with a 6.7L diesel engine and built on or before 21-Aug-2017 may exhibit an illuminated malfunction indicator lamp (MIL) with diagnostic trouble code (DTC) P203B. This may be due to a low voltage condition during engine cranking. To correct this condition, reflash the diesel exhaust fluid (DEF) reductant level sensor/quality module using the Urea Sensor Reprogramming tool.

Summary
This article supersedes TSB 17-0068 to update the Service Procedure and Part List.
Issue: Some 2016-2017 F-650/F-750 vehicles equipped with a 6.7L diesel engine and built on or before 21-Aug-2017 may exhibit an illuminated malfunction indicator lamp (MIL) with diagnostic trouble code (DTC) P203B. This may be due to a low voltage condition during engine cranking. To correct this condition, reflash the diesel exhaust fluid (DEF) reductant level sensor/quality module using the Urea Sensor Reprogramming tool.
Action: Follow the Service Procedure steps to correct the condition on vehicles that meet all of the following criteria:
- 2016-2017 F-650/F-750
- 6.7L diesel
- Built on or before 21-Aug-2017
- Illuminated MIL with DTC P203B
Special Tool(s)
Urea Sensor Reprogramming Tool
418-665
Service Procedure
1. Turn the vehicle ignition to the OFF position.
2. Locate the reductant tank on the side of the vehicle.
3. Remove the 4 skid plate retainers and then remove the skid plate. Do not remove the reductant tank. (Figure 1)
Figure 1
4. Locate the 4 pin electrical connector for the reductant level sensor/quality module (part of the reductant tank). (Figure 2)
Figure 2
5. Carefully unlatch the white secondary lock, depress the tab and remove the connector from the reductant level sensor/quality module. (Figure 3)
Figure 3
6. Is part number GC4A-5J242-AD printed on the component side of the reductant level sensor/quality module 4 pin electrical connector?
(1). Yes – proceed to Step 7.
(2). No – this article does not apply. Refer to the Powertrain Control and Emissions Diagnosis (PC/ED) Manual for additional diagnostics.
7. Connect the Urea Sensor Reprogramming tool into the reductant level sensor/quality module on the reductant tank. (Figures 4-5)
NOTE: When using the Urea Sensor Reprogramming tool for the first time, remove the plastic tab from the battery compartment to power the tool.
Figure 4
Figure 5
8. Once the Urea Sensor Reprogramming tool is connected, move the toggle switch to the ON position. The top green light emitting diode (LED) will illuminate and the software reprogramming process for the reductant level sensor/quality module will begin automatically. (Figure 6)
Figure 6
9. Allow up to 60 seconds for the tool to complete reprogramming the reductant level sensor/quality module.
10. Does the bottom LED on the Urea Sensor Reprogramming tool illuminate green? (Figure 7)
Figure 7
(1). Yes – the reductant level sensor/quality module has been successfully reflashed. Disconnect the Urea Sensor Reprogramming tool from the reductant level sensor/quality module and reconnect the 4 pin electrical connector from the wire harness. Re-install the reductant tank skip plate on to the reductant tank. Repair is complete.
(2). No – proceed to Step 11.
11. Is the bottom LED illuminated red?
(1). Yes – make sure the Urea Sensor Reprogramming tool is securely connected to the urea sensor and turn the reprogramming tool off then turn it back on again to restart the reprogramming process. Allow up to 60 seconds for the tool to complete reprogramming the reductant level sensor/quality module. Return to Step 10.
(2). No – proceed to Step 12.
12. Are both the red LED and green LEDs flashing?
(1). Yes – replace the 9 volt battery in the Urea Sensor Reprogramming tool. Make sure the Urea Sensor Reprogramming tool is securely connected to the urea sensor and turn the reprogramming tool off then turn it back on again to restart the reprogramming process. Allow up to 60 seconds for the tool to complete reprogramming the reductant level sensor/quality module. Return to Step 10.
(2). No – the reductant level sensor/quality module has been successfully reflashed. Disconnect the Urea Sensor Reprogramming tool from the reductant level sensor/quality module and reconnect the 4-way connector from the wire harness. Install the stone shield on the tank assembly using the 3 push pins. Repair is complete.

- Meets GM Original Equipment specifications to be approved for use in GM vehicles as well as in non-GM diesel vehicles that have an SCR (Selective Catalytic Reduction) system to meet regulated NOx emissions (Based on EPA certification testing. Your actual emissions will vary based on several factors including temperature, terrain, and driving conditions).
- High quality formula is made from high purity urea and deionized water.
- Meets API regulations and ISO 22241 standard for purity and concentration
- Nozzles sold separately
- One gallon of BlueDEF is used approximately every 300 miles
- A truck with a 20 gallon DEF tank can go up to 6000 miles between fill-ups
- When used in an SCR system BlueDEF will reduce the levels of NOx emissions of those engines
- Non-flammable
- Diesel exhaust fluid
- Prime Guard DEF is a safe, environmentally friendly solution for Selective Catalytic Reduction
- Prime Guard DEF meets the stringent ISO 22241, AUS 32 and DIN 70070 standards for purity and concentration
- Prime Guard DEF is an ultrapure, formaldehyde-free, NOx reducing treatment specifically formulated for diesel engines equipped with SCR systems
- Prime Guard DEF is API certified, guaranteeing the quality and suitability for proper SCR operation
- Prime Guard DEF 2.5 Gallon single-pack box includes a dispensing nozzle for an easy pour
- Excellent for diesel vehicles driven regularly at slow speeds, low loads, short durations or make frequent stops as these are more prone to having the problem of crystallization deposit build up in the SCR system.
- Regular use every 5,000 miles not only keeps the system clean, but works to prevent the white crystallization issues from returning.
- Will not void manufacturer’s new vehicle warranty. Specifically designed and safe to use on vehicles which have DOC catalytic converters, DPF particulate filters, SCR selective catalytic reduction devices, ASC ammonia slip catalyst or DEF / AdBlue systems.
- Works with all AdBlue, Aria 32 (Automotive Nitrogen Oxide Liquid Reducing Agent), AUS 32 (Aqueous Urea Solution), BlueHDi, BlueTEC, Cummins, DEF UREA, Duramax, EcoDiesel, PowerStroke, TDI Clean Diesel, and many more.
- DEF Crystal Clean is specifically designed to only be installed in the Diesel Exhaust Fluid / AdBlue tank which usually has a blue cap. Do not add to the diesel fuel tank.
