Kia Optima: Variant coding
After replacing the SRSCM with a new one, the “Variant Coding” procedure must be
performed.
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. |
2. |
If the variant coding
is failed, DTC B1762 (ACU Coding Error) will display 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. |
3. |
If the battery voltage
is low (less than 9V), DTC B1102 will be displayed. In this case,
charge the battery before performing the variant coding procedure.
DTC B1762 (ACU Coding Error) and B1102 (Battery Voltage Low)
may be displayed simultaneously.

Variant coding Procedure
1. |
With the ignition "OFF", connect
GDS. |
2. |
Ignition "ON" & Engine "OFF"
select vehicle name and airbag system. |
3. |
Select Variant coding mode. |
4. |
Follow steps on the screen as
below. |
1) Initial ACU Variant Coding screen
2) VIN Code entering screen
3) Variant coding's proceeding screen-1
4) Variant coding's proceeding screen-2
5) Variant coding is completed
1) This screen is opened when you try the variant coding again on the SRSCM
that already has the variant coding performed.
2) If communication fails, the following screen will appear.
|
■ Off-line type on GDS (This can be used when not connecting to internet)
1) Initial
ACU Variant Coding screen
2) ACU Coding Code entering screen
3) Screen of rechecking ACU Coding code's entering
4) Variant coding's proceeding screen-1
5) Variant coding's proceeding screen-2
6) Variant coding is completed
1) This screen is opened when you try the variant coding again on the SRSCM
that already has the variant coding performed.
