Variant Coding

After replacing the SRSCM with a new one, the "Variant Coding" procedure MUST be performed.

NOTE:
  1. In SRSCM variant coding mode, the airbag warning lamp periodically flickers (ON: 0.5sec., OFF: 0.5sec.) until the coding is normally completed.
  2. If the variant coding has failed, DTC (ACU Coding Error) will be displayed and the warning lamp will be turned on.

    In this case, perform the variant coding procedure again after confirming the cause in "DTC Fault State Information".

    Variant Coding can be performed up to 255 times, but if the number of coding work exceeds 255 times, DTC (Exceed Maximum coding Number) will be displayed and SRSCM must be replaced.

  3. If the battery voltage is low (less than 9V), DTC will be displayed. In this case, charge the battery before anything else, and then perform the variant coding procedure.

    DTC (ACU Coding Error) and (Battery Voltage Low) may be displayed simultaneously.
