3.2.8 T-Flash fault
FS501 T - Flash circuit is connected with CPU through the special SDIO bus, circuit diagram
shown below. T - Flash the common faults and reasons are:
1, T – Flash read-write test is failure
1) T - flash for fault card or and T kaka seat have had no contact with good
2) below the resistance there may be short circuit, or virtual welding phenomenon. Capacitance
may on short circuit. (using a multimeter to test whether T card signal and ground and VMCH
short circuit can eliminate)
3) software reason
2, T card not to know card: T holder PIN feet virtual welding, on MLV welding reverse and
capacitance breakdown
3, T - Flash can't through the USB for transmission
1) T - Flash itself, speaking, reading and writing test failure fault
2) software fault 3) USB fault
T card circuit
3.2.9Touch Panel function
Touch Panel common fault and reasons are:
1,The Sensor sensitivity low, slow reaction: software problem
