Description of Self-test Test Items C-17
 Analysis to test failure
The drive goes wrong if the test result appears Error.
Backlight control of LCD monitor goes wrong if the test fails.
 Suggestion to failure test
a) Restart the device and perform the self-test if the test result appears Error. It is
necessary to restore the device if Error re-appears.
b) It is recommended to replace CPU if the test result is FAIL.
C.1.37 Z0801 Left Battery I2C Interconnection Test
 Top test items
DSP FPGA and SM ARM Interconnection Test
 Test content
Read the left battery status when it is on the site via SM serial port, and test whether
12C bus communication between left battery and SM ARM works well.
 Analysis to test failure
The drive goes wrong if the test result appears Error.
The left battery and SM ARM go wrong if the test result is FAIL.
 Suggestion to failure test
a) Restart the device and perform the self-test if the test result appears Error. It is
necessary to restore the device if Error re-appears.
b) It is recommended to replace the left battery, and then replace CPU board if the
test result is FAIL.
