C-20 Description of Self Test Items
C.1.43
Z1501
MF FPGA and SM ARM Interconnection Test

Top test item
Communication self test between PC Module and MF FPGA

Test content
Test whether UART communication between MF FPGA and battery management ARM works well.
Send the order through SM serial port drive, and re-read the data via the serial port.

Analysis to test failure
The drive goes wrong if the test result appears Error .
UART interconnection between MF FPGA and battery management’s ARM goes wrong if the test
fails.

Suggestion to failure test
Restart the device to perform the self test if the test result appears Error. It is necessary to restore
the device (OS+doppler) if Error re-appears.
It is recommended to replace the battery management board if the test result is
FAIL
.
C.1.44
Z1502
Battery I2C Interconnection Test

Top test item
Communication test between MF FPGA and battery management ARM

Test content
Read the position of battery via SM serial port, and test whether 12C interface communication
between battery and battery management ARM works well.

Analysis to test failure
The drive goes wrong if the test result appears Error .
The interconnection between left battery and battery management ARM goes wrong if the test
result is
FAIL
.

Suggestion to failure test
Restart the device to perform the self test if the test result appears Error. It is necessary to restore
the device (OS+doppler) if Error re-appears.
It is recommended to replace the battery, and then replace battery management board if the test
result is FAIL .
C.1.45
Z1503
Battery Test

Top test item
12C interconnection self test of battery

Test content
Read the voltage, temperature, current, volume and charging times, etc., of the battery via SM
serial port.

Analysis to test failure
The drive goes wrong if the test result appears Error .
The interconnection between the battery and battery management ARM goes wrong if the test
result is FAIL .
