Current DTC and history DTC can be identified by lighting and flashing of ªAIR BAGº warning lamp as
follows.
Current DTC is set.
(Abnormality exists at present.)History DTC is set only. (Faulty condi-
tion occurred once in the past but nor-
mal condition is restored at present.)

Current DTC is displayed.History DTC is displayed.
However, if a multiple number of DTC's are set an even one of them is a current DTC, ªAIR BAGº warning
lamp remains on after ignition switch is turned ON. Therefore, it is not possible to identify any of them
as to whether it is a current one or a history one. (But use of scan tool (Tech 1) will make identification
possible.)
