Motorola Mobility Confidential Restricted:
Do not share without consent from Motorola
In the event of charging issues, check charging voltages along the charging path:
● Check the battery is inserted the CON1002 or not
● Check battery ID voltage at TP1006 about 1V
● Check thermistor voltage at TP1005 about 0.63V
● Measure USB_PWR charger input voltage at TP1004. The voltage should
be between 4.75V~5.25V.
● Measure VCHG voltage at C1012. The voltage should be lower the
USB_PWR.
● Check battery voltage at CON1002 pin4. It should be 4.35V or lower. If
battery is 2.1 or 0, there maybe a short in the circuit somewhere. The battery
fault safe circuit is triggered.

sensor wrong reading
• Check I2C bus activities during ALS + proximity sensor access
(SENSORS_I2C_SDA, SENSORS_I2C_SCL)
• Check CON101 on ALS + Proximity sensor FPC and CON2101 on phone
board are corrected soldering
In the event of ALS + proximity sensor issue at phone level:
• Check for missing/missed alignment of rubber seal
• Missing/missed alignment of rubber seal can cause ALS + proximity
sensor wrong reading

• uSD connector is operated with its own power, detection and SDC bus
interface
In the event of uSD issue:
• Do a through visual check on uSD connector CON103 for any sign of
mechanical contact issues
• Insert uSD and detected SD_CARD_DET_N=low at TP1711
• Check the voltage VREG_L18_2P95 at TP1712 on board level
• Check uSD bus interface signal activities during uSD access (SDC_CLK,
SDC_CMD, uSD_DATA)

2) Check power supply voltages;
a. V_TP_3P1(C1823 ) = 3.1V
b. VREG_LVS1_1P8 (C1815) = 1.8V
3) Measure INT, RST,I2C signal are correct

1. Check Backlight Power Supply voltages:
a. LED+ (C1812)
b. LED1- (C1819)
c. LED2- (C1820)
2. Check LCM Power Supply voltages:
a. +5.5V (C1802)
b. -5.5V (C1804)
c. LCD_IOVDD (C1809)
• Check to make sure there is data activity on all MIPI differential pair
lines while display is on (TP1801,TP1802,TP1803,TP1804).
• Check reset line CON1801 pin 22. It should be set high (1.8V) after

If the Primary mic is not functioning…
• Check mic bias at C1624. This should be 1.8V when the microphone is
enabled.
• Check the microphone assembly to make certain it is not damaged, which may
indicate a broken diaphragm
