Chevrolet Sonic Repair Manual: Window Motor Programming - Express Function

Window Motor Normalized Procedure

A window motor that has not been normalized will no longer perform the express up and express down functions, this may occur during the following conditions:

• When a window motor has been disconnected
• When a door harness has been disconnected
• When the battery has been disconnected or replaced

Note:

When DTC B3205?€‰4B is set, the following warnings will be displayed on the driver information center:

Open, then Close Driver Window

These warnings will clear once the window has been "Normalized" and the DTC will clear.

To normalize the window motor, follow these steps:

Note:

The doors must be completely closed prior to normalizing the windows, a door that is open or ajar may cause the power window to function abnormally or to become inoperative while performing the normalizing procedure. If this occurs, verify that the door is completely closed then repeat the normalizing procedure.

1. Ignition ON.
2. Starting with the window completely UP, press and hold the power window switch until the window is fully open and continue holding the switch down for approximately 5?€‰seconds after the window is completely open.
3. Pull the power window switch up until the window is fully closed and continue holding the switch up for approximately 5?€‰seconds after the window is completely closed.

The window should now be normalized and the window should perform the express up and express down functions.

Window Motor Relearn Procedure

A relearn procedure may need to be performed for any Local Interconnect Network (LIN) window motor for the following conditions:

• When the window glass is out of alignment
• When the window glass has been replaced
• When the door has been replaced
• When the window regulator has been replaced

Note:

Prior to performing the relearn procedure the vehicle must have all 4?€‰wheels properly inflated and mounted, the vehicle must be sitting on a level surface and all doors must be completely closed.

To relearn the window motor, follow these steps:

1. Ignition ON.
2. With a scan tool, select Module Diagnosis, Body Control Module, Configuration/Reset Functions and then select the appropriate Clear Window Learn Values for the window motor requiring the relearn procedure.
3. After the learn procedure, exit the scan tool learn procedure completely, the power window cannot be normalized and will not function until you exit the program.
4. Starting with the window completely UP, press and hold the power window switch until the window is fully open and continue holding the switch down for approximately 5?€‰seconds after the window is completely open.
5. Pull the power window switch up until the window is fully closed and continue holding the switch up for approximately 5?€‰seconds after the window is completely closed.

The window is now reprogrammed.
