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.
Cars without pinch protection : the button has one position.

Procedure M03

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.

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.

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.

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

Procedure M04-

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."

1.c.

1.d.

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.

4D/5D M05-M06: If the fault remains, proceed to step 2.

4D/5D M07-: If the fault remains proceed to step 3.

CV M04-06: If the fault remains, proceed to step 2.

CV M07-: If the fault remains, proceed to step 3.

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

If the software number is older than those specified above :

Connect Tech2 (version 126.000 or later) and perform update. Add the door control module with Tech2 under menu All - Add / Remove. Check the operation.

4D, M04 : If the fault remains, carry out checking and fault diagnosis M03-M04, see page 8.

4D/5D M05- If the fault remains, proceed to step 3.

CV : If the fault remains, carry out the CV procedure, see page 10.

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

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.

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.

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.

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.

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.

If the test is OK, proceed to step 18.

In the event of error messages, proceed to step 8.

Error message: "Check/adjust window anchorage point/window lift". The difference in clamping force for the first 20 mm is higher than 20, check the window anchorage point/window lift.

Carry out step 7 again and check the improvements.

Read out the following read values in Tech2 under Read Values - Advanced, miscellaneous:

9.a.

False pinch protection activation during whole cycle : Lower the window to the bottom. Activate "Express up" and check the read values following pinch protection activation.

Check the mechanics in accordance with steps 11-18. Use "Position of max. force" to locate the problem area.

9.b.

False pinch protection activation at turning centre of window : Lower the window, stop and raise it before it has reached the bottom position. Read off the values following pinch protection activation.

Check the window anchorage point if "Force difference first 20 mm" is higher than 20.

In the event of a value above 20, carry out step 15.
