General Description
When the new SRSCM is set up on a vehicle by SRSCM's failure, SRSCM(ACU) Variant coding must be performed.
Since a new SRSCM is normally supplied with unsetting state, the ACU has to be set up based on the vehicle specificaions by operating ACU Variant Coding procedure.
The SRSCM checks its specifications in it in order to run its airbag system normally.
If the warning light of airbag is flickering continuously, that is because SRSCM(ACU) Variant Coding is not completed.
noteSRSCM Variant Coding is available only one time. And when it is already finished, it is impossible to retry SRSCM Variant Coding.
Warning lamp's operation during SRSCM(ACU) Variant Coding Mode : It will be flicking on every 1 seond before the Variant Coding is normally done.
DTC Description
In order to run the airbag system normally, check if there is an incorrect vehicle specfications at performing SRSCM(ACU) Variant Coding. This DTC is set up if SRSCM's variant code doesn't match with the entering variant code at performing SRSCM(ACU) Variant Coding procedure.
