Pinch protection activates

Cars affected Saab 9-3 equipped with pinch protection: 4D/5D: M03- CV: M04- Background The software for pinch protection functionality has been improved from M07 in order to prevent the pinch protection from activating, which means that the window cannot be closed even if there is nothing obstructing it. The software is also available for older cars as per above (does not apply to 4D M03). The software also includes diagnostic and fault diagnosis options (does not apply to CV and 4D M03-M04). The control module must not be replaced when the pinch protection incorrectly activates, as the fault is not in the control module. In order to facilitate fault diagnosis, two new tests and new read values have been added into Tech2 (not CV and 4D M03-M04). The tests and read values are oriented toward adaptation performance and mechanical problems. As the pinch protection system is adaptive the adaptation performance is one of the most important parameters. A system with poor adaptation performance is more likely to activate the pinch protection incorrectly. One of the reasons the pinch protection may activate before the window is closed is that the window's actual position does not correspond to the programmed position. This means that the window lift motor will not stop at the end position but instead will back up a bit. In the case of customer complaint, the following procedure must be carried out. Symptom description

The pinch protection activates before the window is closed. Parts required As required, see EPC for part numbers. Note

First ensure the car is fitted with the pinch protection. Lift up the window lift button.

Cars with pinch protection: the button has two positions.

Page 2: TECHNICAL SERVICE BULLETIN Pinch protection activates …downloads.innova.com/tsb-files/76000/831-2639 ed. 4.pdfDDM 12774949-AA PDM 12774950-AA Car variant - Model year Software number

Cars without pinch protection: the button has one position.

Procedure M03

1. Check if the window's actual position corresponds with the programmed position.

1.a. Do not program.

1.b. Raise the window using "Express Up." If this is not possible, temporarily disconnect the pinch protection so that the window can be closed. The ignition should be in the ON position. Hold down the disconnect button for the rear window lifts in the driver door (the button must be depressed the entire time the window is closing). Close the applicable window. The next time the window lift is used, the pinch protection will be active again.

1.c. Use Tech2 and check that the read values show that the window is closed. Body - Power Windows - option Driver/Pass door - Read Values. Select using operation button - advanced operation - select group. Read in menu Window position xxx counts - Window, programmed upper stop xxx counts.

1.d. Calculate the difference between the actual upper stop position and the programmed actual stop position by taking the values from pos 1 c "Programmed upper stop" minus "Window position," e.g. 1168 - 1151 = 17. If the value is higher than 15, change the window lift's electric motor and then program.

2. If the fault remains, carry out checking and fault diagnosis M03-M04, see page 7. If the fault has been rectified, then no additional steps are necessary.

Note

If the door control module has been replaced and is M04- then the window lift must be from M04-.

If the window lift has been replaced and is M04- then the door control module must be from M04-.

To distinguish the window lift from M03 and M04-, check the colour of the pulley behind the window lift motor.

M03= White

M04= Light brown/beige

Check the above in order to avoid the pinch protection incorrectly deploying.

3. If the problem remains following the above fault diagnosis, then the pinch protection can be deactivated using Tech 2 (version 127.000 or later) under the menu entitled Fault diagnosis - Model year 2003 - Saab 9-3 Sport (9440) - All - Service - Activate/Deactivate pinch protection.

Procedure M04-

Note

This deactivation means that the "Express up" function is deactivated.

1. Check if the window's actual position corresponds with the programmed position.

1.a. Do not program.

1.b. Raise the window using "Express Up." If this is not possible, temporarily disconnect the pinch protection so that the window can be closed. The ignition should be in the ON position. Hold down the disconnect button for the rear window lifts in the driver door (the button must be depressed the entire time the window is closing). Close the applicable window. The next time the window lift is used, the pinch protection will be active again.

1.c. Use Tech2 and check that the read values show that the window is closed. Body - Power Windows - option Driver/Pass door - Read Values. Select using operation button - advanced operation - select group. Read in menu Window position xxx counts - Window, programmed upper stop xxx counts.

1.d. Calculate the difference between the actual upper stop position and the programmed actual stop position by taking the values from pos 1 c "Programmed upper stop" minus "Window position," e.g. 1168 - 1151 = 17. If the value is higher than 15, change the window lift's electric motor and then program.

4D, M04: If the fault remains, proceed to step 2.

If the fault is rectified then no additional steps are necessary.

3. Raise and lower the window several times. If the pinch protection deploys each time the window is raised, proceed to step 9. If the pinch protection deploys sporadically, proceed to step 4.

4. If the pinch protection deploys while raising from the bottom position, proceed to step 5. If the pinch protection deploys during raising following lowering, but not to the bottom position, proceed to step 7.

5. Perform the adaptation test. Start the test in Tech2 under Body - Power Windows - Driver Door/Passenger Door - Miscellaneous - Adaptation test window system. The windows will now be lowered and raised 10 times in order to test the adaptation performance and to read the clamping forces.

The test is now complete.

6. If the test is OK, proceed to step 18. In the event of error messages, proceed to step 6a.

6.a. Error message: "Slow mechanical system". Max. clamping force is higher than 70, the window runs slowly. Check the mechanical system in accordance with steps 11-17. Use the read value "Position of max. force (mm)" in order to locate the problem area.

Check the adjustments using the read values. Then proceed to step 18.

6.b. Error message: "Mechanical problem, adjust window lift/window seal". Check the mechanical system in accordance with steps 11-17.

Check the adjustments using the read values. Then proceed to step 18.

6.c. Error message: "Poor adaptation performance". Adaptation approved less than 8 out of 10 times. The system cannot adapt itself. Carry out the programming of the window in accordance with step 18 and repeat the adaptation test. Note that several messages may arise at the same time. In which case carry out the mechanical fault diagnosis first.

7.

Carry out the Window opening/Closing test. Start the test in Tech2 under "Body - Power Windows - Driver Door/Passenger Door - Miscellaneous - Window opening/Closing test. The test is used to check whether the window is unsteady during the change of direction which creates the so-called "drawer effect". Tech2 opens the window to the selected opening point and closes it again. Start the test, open 1/3, 1/2 and 2/3.
