DIAGNOSIS:
1.
2.

4.
5.
6.

Position the vehicle at the workplace.
Open the engine hood.
Fit the bodyguards (fenders and front bumpers).
Run the motor up to the working temperature.
Connect wiTECH to the vehicle.
Access the injection ramp pressure values in the injection control module (ECM) in graphical mode. To do
this, choose the following parameters:

● Engine speed (or engine speed).
● Fuel rail pressure (or Fuel pressure instruction on common ramp high fuel pressure).
● Desired Fuel Line Pressure (or Common Fuel Injection Chute Pressure).
7. Observe if the graph read on the vehicle is as shown in the images of the examples below.

Fig. 1
Graphical Mode - KO Result
8. Monitor wiTECH whether the high-pressure fuel pump will deliver the desired pressure immediately at the
time of start-up when the failure occurs:
9. Is there a delay in the pressure increase or does the actual pressure not reach the desired pressure?
● YES >>> Print or capture the image (print screen) showing the injection ramp pressure loss failure with
the parameters "Fuel rail pressure" and "Desired fuel line pressure" (for possible warranty submission)
and proceed to the next step.
● NO >>>Do not apply for this TSB.
10. Disconnect the contact (key-off).
11. Mount the pressure gauge on the low-pressure line between the fuel line and the inlet of the high-pressure
fuel pump.
12. Start the engine (key-on).
13. Measure the fuel pressure of the low-pressure line with the pressure gauge mounted between the fuel line
and the high-pressure fuel pump during the evaluation of the vehicle with the fault:
● If the pressure measured on the pressure gauge is between 5.2 and 6.0 bar, but the rail pressure
(injector ramp) measured does NOT follow the desired pressure in the parameters via wiTECH, take a
screenshot or PDF print of the screen demonstrating the incident and perform the INJECTION SYSTEM
CLEANING PROCEDURE.
● If the pressure measured on the pressure gauge is between 5.2 and 6.0 bar and the rail pressure
(injector ramp) measured follows the desired pressure in the parameters via wiTECH, DO NOT apply
this bulletin.
● If the pressure measured on the pressure gauge is below 5.2 bar, it indicates a failure of the lowpressure pump or other component. Therefore, DO NOT apply this bulletin.

**INJECTION SYSTEM CLEANING PROCEDURE:
1.

4.
5.

Open the hood of the vehicle.
Fit the bodyguards (front fenders and front panel).
Open the fuse box cover in the engine compartment.
Remove the F009 fuse from the fuel pump.
Start the engine and keep it running until it stops running due to lack of fuel. Repeat this procedure
described above three times to ensure that the fuel supply line is completely depressurized.
6. Remove the F009 fuse of the fuel pump.
7. Close the fuse box cover in the engine compartment.
8. Remove the complete air filter.
9. Disconnect the fuel inlet quickly coupling at the high-pressure fuel pump and insert a plug to ensure the
pipe seals.
10. Prepare the "IT200E - GDI Flex Injector Cleaner Applicator" kit (PN: 2850000486), according to your
equipment user manual.
11. Insert the quick coupling of the tool "IT200E - GDI Flex Injector Cleaner Applicator" (PN: 2850000486) into
the inlet of the high-pressure fuel pump.
12. Pour the additive "Isotech 012 GDI Injector Cleaner" (PN: 2850000479) into the cylinder of the tool "IT200E
- GDI Flex Injector Cleaner Applicator" (PN: 2850000486).
13. Pressurize the "IT200E - GDI Flex Injector Cleaner Applicator" kit (PN: 2850000486), according to your
equipment user manual.
14. Start the engine.
15. Run the vehicle at idle speed until the product is finished when the engine turns off by itself.
16. Disconnect the equipment from the vehicle's power system.
17. Reconnect the quick fuel inlet coupling to the high-pressure fuel pump.
18. Reassembly the complete air filter.
19. Delete the DTCs recorded in the ECM control panel's memory with wiTECH.
20. Perform injector learning with wiTECH.
WARNING!
Learning the injectors with wiTECH is essential after replacing the injectors, at the risk of
generating DTC P0171 and/or P0172.
21. Start the engine and keep the engine running.
22. Monitor once again with wiTECH whether the high-pressure fuel pump will deliver the desired pressure
immediately at the time of start-up when the failure occurs (as requested in the "DIAGNOSIS" section).
23. Is there yet a delay in the pressure increases or does the actual pressure not reach the desired pressure
(as requested in the "DIAGNOSIS" section)?
● YES >>> Print or capture the second image (print screen) showing the injection ramp pressure loss
failure with the parameters "Fuel rail pressure" and "Desired fuel line pressure" after INJECTION
SYSTEM CLEANING PROCEDURE and perform the REPAIR PROCEDURE.
● NO >>> The incident has been resolved. Print or capture the second image (print screen) showing the
injection ramp pressure with the parameters "Fuel rail pressure" and "Desired fuel line pressure" after
INJECTION SYSTEM CLEANING PROCEDURE.
24. Remove the bodyguards on the front fenders and bumpers.
25. Close the hood of the vehicle.
26. Remove the vehicle at the workplace.
27. Release the vehicle for delivery to the customer.**

REPAIR PROCEDURE:
WARNING!
**The replacement of the high-pressure fuel pump will be applicable only if the injection system
cleaning procedure is not effective.
1. Replace the high pressure fuel pump. Refer to the detailed service procedures available in
DealerCONNECT/Service Library under: Service Info>1056F72 - Bomba de Pressão - Remoção/
Recolocação.
2. Delete the DTCs recorded in the ECM control panel's memory with wiTECH.
3. Perform injector learning with wiTECH.

WARNING!
Learning the injectors with wiTECH is essential after replacing the injectors, at the risk of
generating DTC P0171 and/or P0172.
Start the engine and keep the engine running.
Remove the bodyguards on the front fenders and bumpers.
Close the hood of the vehicle.
Remove the vehicle at the workplace.
Release the vehicle for delivery to the customer.

IMPORTANT! When it is found that there is a need to replace the high pressure fuel pump, it is
necessary to attach the Vehicle Scan Report generated by wiTECH (containing the DTCs
stored in the memory of the ECM center) to the SCP system and the screenshots or PDF
printouts of the screen demonstrating the failure before and after the cleaning procedure
of the high pressure fuel pump for the said Warranty Claim (SG). The chassis and data
regarding the vehicle must be properly entered into wiTECH so that it can be correctly
identified. If this does not occur, the Warranty Request (SG) may be reversed. For
more information, please refer to the current Warranty Manual and Stellantis Practical
Information.
NOTE: After applying this TSB, it is not necessary to send DID-I or DID-A.**
