Condition Two different conditions:

  1. Difficulty in completing a diesel particulate filter (DPF) regeneration during specific/short drive cycle conditions.
  2. Soot jump events. This is when the soot collapses in the DPF which causes a sudden high flow resistance and sets a DTC P2463 (with a Service Vehicle Soon message) or P242F (with a Check Engine Lamp on and ‘Reduced Power Mode’). The customer will require to visit a dealer to rectify the concern.

 

Either condition can result in diagnostic trouble codes (DTC’s) being logged and the service vehicle soon (SVS) message on the cluster. The vehicle may also go into “Reduced Power Mode” requiring dealer interaction to attempt a service regeneration or replacement of the diesel particulate filter (DPF).

Correction Those vehicles flagged (may or may not present with the above conditions) are require to be actioned with the following steps:

 

fuse 35(UA)

fuse 35(UA)
Important: To prevent programming failures, please adhere to SPS guidelines detailed in DL2017–28 (25 Sept 2017).

Prior to SPS programming the ECM, remove fuse 35(UA) from the underhood fuse box.

After successful SPS programming refit fuse 35(UA) in the underhood fuse box.

GM Diagnostic/Programming (TIS2Web)

Approved J2534 Device with TIS2WEB can reprogram 1996 and later All GM Modules.

To obtain the latest electronic controller calibration information for your vehicle, go to https://tis2web.service.gm.com/tis2web and enter the vehicle’s 17 character Vehicle Identification Number (VIN) and select ‘Get CAL ID’.

You can then compare the latest part number with the actual number installed on the vehicle to determine if a reprogram is needed.

The Service Programming System (SPS) application is part of the TIS2Web system. To program an ECU, the SPS application must communicate with the vehicle control modules using the proper J2534 programming interface tool.

The following are the supported interface tools:

The Tech 2 supports model years 1996 and beyond. With the addition of the CAN Diagnostic Interface (CANdi) module, Tech 2 is fully backward compatible with current Tech 2 functionality and operates transparently when diagnosing non-CAN-equipped vehicles.

Servicing the next generation Global A vehicles will require the diagnostic software, GDS2, Global Diagnostic System 2 running on a local PC device while the MDI is connected to the vehicle.

The GM MDI is the Global Diagnostic tool for future vehicles starting with Global A vehicles. The GM MDI was introduced in the fall of 2007 for Pass-Thru programming and offers faster programming speed. It can be used to perform Pass-Thru programming on all vehicles built since 1996 and into the future. Click here to view a list of GDS supported vehicles.
