Variant Coding: Notes

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

NOTE:
  1. On SRSCM variant coding mode, the airbag warning lamp periodically blinks (ON: 0.5sec., OFF: 0.5sec.) until the coding is normally completed.
  2. If the variant coding fails, DTC B1762 (ACU Coding Error) will be displayed and the warning lamp will turn 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 B1683 (Exceed Maximum coding Number) will be displayed and SRSCM must be replaced.
  3. If the battery voltage is low (less than 9V), DTC B1102 will be displayed. In this case, charge the battery before anything else, and then perform the variant coding procedure.

    DTC B1762 (ACU Coding Error) and B1102 (Battery Voltage Low) may be displayed simultaneously.
