11.5.7 Diagnostic Information and Procedures
11.5.7.1 Diagnosis Description
Refer to 11.5.2 Description and Operation get familiar with the system functions and operation before start system diagnostics, so
that it will help to determine the correct diagnostic steps, more importantly, it will also help to determine whether the customer
described situation is normal.
11.5.7.2 Visual Inspection
– Check installed aftermarket equipments that may affect the power windows and power mirrors operations.
–
Check the easy to access system components to identify whether there is a significant damage or potential malfunction.
– Check whether the window initialization failed.
11.5.7.3 Control Module Diagnostic Information
Power window control module reports the following failures through the LIN bus:
–
Motor / Relay Malfunction
– Hall Sensor Malfunction
– Thermal Protection Triggered
– Up Button Is Pressed
– Down Button Is Pressed
11.5.7.4 Glass Regulator Initialization (If Window Express Down Feature Is Available)
–
To initialize the system, the glass must be up all the way to the top, and the switch is pressed to lift the window glass until the
control module stops the glass motor (within 1s after the glass reaches the top). Each time the system lost initialization, repeat
these steps to restore the window express down function.
– Initialization, all system functions must be operational.
– Initialization, the control module voltage should not drop to below 9 V.
– When the control module supply voltage drops momentarily, but the voltage is still higher than 6V, the initialization is effective.
–
Every time the glass is lift to the top till stop using automatic mode (at the top position); system will obtain the latest top position
and overwrite the previous value to calculate the top position.
Note
– Only when the new value is in the calibrated value range, it overwrites the original value, otherwise the control
module will ignore the new value.
–
If the initialization process has not been implemented or have been lost, system does not provide automatic up,
express down and comfort closing function. Manual up, down and auto-down feature can be operated.
In the following circumstances, the initialization will be lost (If window express down is available is equipped)
– Power supply is cut off.
– When the glass is moving up, the power supply voltage drops below 6 V.
–
Control module can not detect logical Hall sensor signals.
– Window glass moves to a location outside the operating range.
