Status Contents
Search Mode Initial status after start.
Search wireless terminal (Initial mode, Parameter writing wait

Inspection Mode Perform diag communication with the vehicle through wireless
terminal (Inspection mode).
Parameters Write Mode Write parameter for wireless terminal (Parameter write mode).
Write BodyNo mainly.
Maintenance Mode Change wireless ST parameter (Through wired LAN)。
No wireless communication at this mode.
●Operation mode of wireless terminal
Status Contents
Initial Mode Initials status after start in BodyNo wireless registered
terminals.
Wait for test mode transition instruction from wireless ST.
Inspection Mode Diag communication is performed. According to wireless ST
instruction,
Diagnostic program communication with vehicle is
performed, and send communication results to wireless ST.
Mode to confirm write completion result.
Software Write Mode Mode that downloads software write data and performs write.
Parameter Write Wait Mode Status of start at BodyNo delete.
Wait receiving shift instruction to parameter write mode.
Parameter Write Mode Register (write) BodyNo that was instructed by wireless ST
register.
Sleep Mode Modes that is running on power savings.
Shift to sleep mode if set time by initial or parameter write
mode is passed.
●[Radio frequency]
Communication is performed out in setting frequency. it is necessary to match the radio frequency of
wireless ST and wireless terminals for communication.

Instruction
Form：DP5-005 Revised：05 11
●[Wireless ID]
Only if wireless ID is matched, it is functioned as receive filter.
Transmitted data from wireless VIM station are identified by wireless terminals in the same radio
frequency or adjacent frequencies.
However, if it was sent in same frequency, it is impossible to communicate normally because of
interference.
(Specials function for being identified by wireless terminals near line)
Keep wireless ID for inspection mode as ID for parameter write wait mode when BodyNO delete so
that next line is not identified incorrectly when Diag when disconnection confirmation after Diag
inspection.
