11.5.7 Diagnostic information and steps

11.5.7.1 Diagnosis descriptions

Refer to 11.5.2 description and operation to get familiar with the system functions and operation
before starting system diagnosis, so that it will help to determine the correct diagnostic steps, more
importantly, it will also help to determine whether the situation described by the customer is
normal.

11.5.7.2 Visual inspection

–

Inspect the after-sales optional device which may affect the normal operation of glass lifter
and electric rearview mirror system.

–

Inspect components easy to access system to identify whether there is a significant damage
that may lead to the fault.

–

Inspect whether the initialization of window is invalid.

–

Inspect battery voltage.

–

Put diagnostic tester into BCM fault memorizer to read fault code.

11.5.7.4 Glass lifter initialization (such as anti-clamp function)

If the system needs to be initialized, the glass must be completely risen to the ceiling and the
switch is held down until the control module stops the glass lifting motor (the window is located at
the top for blockage rotation within 1s). When the system loses initialization at every turn, the
above operation must be repeated to restore the anti-trapping function. After initializing, all
specified system functions must be operated; the voltage on the control mode can not be reduced
to below 9V during initializing; and when the supply voltage on the control module drops
instantly but more than 6V, the initialized state keeps valid.

Notes:

If the initialization procedure has not been executed or has been lost, the anti-trap and comfort
closing functions are not provided. Manual lifting up and down functions and automatic lifting
down function can also be operated.

The following situations will cause the initialization loss (such as anti-trapping function of the
equipment).

–

When the lifter moves, voltage of power supply should be lowered to below 6V.

– Power

supply was cut off

–

Control module detects illogical hall sensor signal.

–

Vehicle window is moved to the position outside the standard operation range.
