Kia Soul: SRS Control Module (SRSCM). Variant coding

Second generation PS (2014-2019) / Kia Soul 2014-2019 PS Service Manual / Restraint / SRSCM / SRS Control Module (SRSCM). Variant coding

After replacing the SRSCM with a new one, MUST perform the “Variant Coding” procedure.

1.	On SRSCM variant coding mode, the airbag warning lamp is periodically blinking (ON: 0.5sec., OFF: 0.5sec.) until the coding is normally completed.

If the variant coding is failed, DTC B1762 (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 B1683 (Exceed Maximum coding Number) will be displayed and SRSCM must be replaced.

If the battery voltage is low (less than 9V) before performing the Variant Coding, DTC B1762 will be displayed only. In this case, charge the battery before anything else, and then perform the variant coding procedure.

Because, although Variant Coding is normally performed, DTC B1762 and low battery are displayed.
