Bonneville V8-4.6L VIN Y (2004)
Service Procedure
Important:
Verify that the 12-volt battery has a battery charge of 12 to 16 volts. The battery must be able to maintain a charge during programming. Only use
approved Midtronics 165-PCS charger to maintain proper battery voltage during programming. The J2534 MDI will reprogram the modules in less time
than the Tech 2(R) scan tool.
1. Reprogram the PCM controller with the updated calibration files using the TIS2WEB Service Programming System (SPS) application.
1.1. Refer to SI and Service Programming System (SPS) documentation for further programming instructions, if required.
1.2. Select J2534 MDI or Tech 2(R) and Reprogram ECU from the Select Diagnostic Tool and Programming Process screen.
1.3. Select PCM Powertrain Control Module from the Supported Controllers screen.
1.4. Follow the on-screen instructions for programming the PCM.
1.5. Using the MDI or Tech 2(R), clear all DTCs if required.
2. Verify SAI pump and valve operation.
2.1. Start and idle the engine.
2.2. Allow the engine to reach Closed Loop.
2.3. Command the SAI System ON with a scan tool. The SAI Pump should turn ON and the Shut-Off valve should open.
2.4. Observe the HO2S Bank 1 Sensor 1 Voltage parameter while the SAI System is commanded ON. The HO2S Bank 1 Sensor 1 Voltage parameter
should decrease below 100mV.
2.5. If the HO2S Bank 1 Sensor 1 Voltage parameter does not decrease below 100mV, refer to DTC P0410 to diagnose and repair the SAI system.
Refer to SI, for DTC P0410 Secondary Air Injection (SAI) System.
3. CALIFORNIA, MASSACHUSETTS, MAINE, & VERMONT VEHICLES ONLY: Install a Recall Identification Label. Also, for California vehicles
complete a "Proof of Correction" certificate upon recall completion.
Recall Identification Label -- California/Massachusetts/Maine/Vermont Vehicles Only
Place a Recall Identification Label on each vehicle corrected in accordance with the instructions outlined in this Product Recall Bulletin. Each label
provides a space to include the recall number and the five-digit dealer code of the dealer performing the recall service. This information may be inserted
with a typewriter or a ballpoint pen.
Put the Recall Identification Label on a clean and dry surface of the radiator core support in an area that will be visible to people servicing the vehicle.
When installing the Recall Identification Label, be sure to pull the tab to allow adhesion of the clear protective covering. Additional Recall Identification
Labels for US dealers can be obtained from Dealer Support Materials by ordering on the web from DWD Store, www.gmdealerworld.com, and then
click on the DWD Store link. Request Item Number S-1015 when ordering.
