Remarks
SQ_IC communication not established
If the signal detection by the module microcomputer is properly performed, the unit operates on an external sync.
If BUSY_SQ remains high, a shutdown is generated.
The written SQ_PROG is incoherent with data on the DIGITAL Assy.
Check the pull-up resistor of the IIC control line and the power to the corresponding IC.
Check the pull-up resistor of the IIC control line and the power to the corresponding IC.
Check the pull-up resistor of the IIC control line and the power to the corresponding IC.
If RST2 does not become high after the unit is turned on, a shutdown will be generated in several seconds.
If TEMP1 that is read by the module microcomputer is 75°C or higher, a shutdown will be generated.
Check the connection with the SENSOR Assy.
Check if the AMP output is short-circuited.
Check if cables are firmly connected.
Check the communication lines (RXD_MOD/RXD_MOD/REQ_MOD).
Check if cables are firmly connected.
Check the communication lines (TXD_IF/RXD_IF/CLK_IF/BUSY_IF/CE_IF/REQ_IF).
Check the communication lines (TXD_IC3/RXD_IC3/CLK_IC3/CE_IC3/IC3_BUSY).
Check the communication lines (EXA/EXDIO).
Check the communication lines (TXD_IC6/RXD_IC6/CLK_IC6/CE_IC6).
Check the communication lines (SCL_AV3/SDA_AV3 or SCL_AV/SDA_AV).
Check the communication lines (SCL_AV3/SDA_AV3 or SCL_AV/SDA_AV).
Check the communication lines (SCL_AV3/SDA_AV3 or SCL_AV/SDA_AV).
Check the communication lines (SCL_AV3/SDA_AV3 or SCL_AV/SDA_AV).
Check the communication lines (SCL_AV3/SDA_AV3 or SCL_AV/SDA_AV).
