Background

The software to the engine management system PSG 16 has been revised on the following points in order to improve drivability.


• Improved cold starting

• Reduction of noise arising in the intake in the event of load changes

• Elimination of torque delay following disconnection of cruise control

• Improvement of torque expansion with acceleration

• Improvement of drive off from a standing start


Symptoms

Poor drivability.



Parts required

Software F5BMLML0

Procedure


Check box C3 on the modification identity plate before taking any action. Continue as follows if the box is not marked.

Read this first!

Check that the computer to be used includes the latest issues of Tech2 and TIS 2000 with the correct versions for SPS programming.

Tools for SPS programming

PC with TIS2000 and WIS installed

Dongle with adapter

Tech 2 with 32 Mbit card

Tech 2’s PC cable with RS232 adapter (max length 10 m)

Battery Tester 311

Pliers

12 Volt current requirement for programming

It is essential that the battery is in good condition in order to carry out successful SPS programming. Before work is started the status of the battery must be checked. This is done using "Battery Analyser 311" Battery tester 86 12 533 (EU) or 86 12 525 (US). Follow the battery tester instructions. Remove the car's main fuses with the battery in order to eliminate "System noise" during the test. Fit the main fuses after the battery test has been carried out.

If necessary charge the battery with low level current (less than 15 A) at the same time as SPS programming is carried out. Avoid rapid charging (above 20 A) as this can disrupt SPS programming.

SPS Programming:

Follow the instructions below carefully for a successful result


1. Read and note the car's VIN.

2. Connect Tech2 to the data link connector and turn the ignition key to the ON position.

3. Start Tech 2 and read off any diagnostic trouble codes from all systems.

4. Select Diagnostics

Then select

Model year: 2002 or 2003

Car Type: 9-5

System: All

System: Read / Clear all DTC information

System: Read all DTC Information

Then follow the instructions in Tech 2

5. Note the diagnostic trouble codes.

6. Go back to the main menu and select Service Programming System (SPS) .

Select Request Information

Then select

Model year: 2002 or 2003

Car Type: 9-5

Group: Engine

System: PSG 16

Then follow the instructions in Tech 2.

7. Connect Tech 2 with dongle to the COM port on the computer via a flat cable.

Note

Tech 2 can be connected to the car and the PC at the same time during the entire SPS programming.


8. Go to the "Start Menu" in Tech 2.

9. Start the program TIS 2000 and select Service Programming System .

Then select:

Diagnostic Tool: Tech 2

Programming progress: Reprogram ECU

ECU location: Vehicle

Follow the instructions and select Next

Verify VIN and select Next

Verify Car data and select Next

If the software in Selected ECU software is newer than the software in Current ECU software, select Reprog

10. After the programme transfer is complete disconnect Tech2 from the computer and reconnect it to the car.

11. Remove the cooling fans' relay "FAN Low" in the relay box in the engine bay.

12. If the car has TCS, remove fuse 29 ABS/TCS/ESP in the dashboard fuse box.

13. Shut down all demanding power consumers: such as lighting, ACC, the audio system, electrically heated seats, seat ventilation, etc.

14. Start Tech2 and select Service Programming System (SPS)

Select Program ECU .

Follow the instructions in Tech 2.

15. Check that the ACC fan is shut down during programming.

16. Wait until the entire SPS programming is carried out. This takes approx. 15 minutes.

17. When the message Programming successful is displayed in Tech 2, SPS programming is finished.

18. Go back to the Main Menu in Tech 2.

19. Fit the cooling fans' relay.

20. Fit TCS fuse 29.

21. Read off diagnostic trouble codes from all systems (see point 3). Compare with any diagnostic trouble codes before SPS programming. If new diagnostic trouble codes are generated then these can have arisen with programming.

22. Rectify and clear any diagnostic trouble codes in all systems.

23. Connect an exhaust extraction hose and start the engine in order to check its operation. Switch off the engine.

24. Disconnect Tech 2 and fold back the data link connector cover.


Marking the modification identity plate

After carrying out the procedures on the cars affected as per MI210-2364, MI210-2366 and MI248-2367 the modification identity plate must be marked in box C3. If the procedure is carried out by the importer, mark the box with the number "7" and if carried out by the dealer with the number "8".
