Vehicle comes into the workshop with the following illuminated:

• Check Engine Light
• DSC warning lamp
• Air bag warning lamps

During diagnosis, the following fault code is found stored in the ASCM (Advanced Crash Safety Module):

• 930C1E, internal ECU error 

If the fault is cleared, it returns immediately.

CAUSE

The root cause is under investigation.

CORRECTION

Perform diagnosis with ISTA.

If only the 930C1E fault is present, reprogram the vehicle.

Repeat the diagnosis with ISTA.

If the fault is still present in the ACSM after programming, replace the ACSM as outlined in the Procedure section.

PROCEDURE

If fault code 930C1E is the only air bag fault stored, program the vehicle with ISTA 4.21.2x (released mid-January 2020) or higher.

• If the ACSM is not on list of modules to be re-programmed, manually select the ACSM to add it to the measure plan for programming. 

If the fault is still present in the ACSM after programming/coding; replace the ACSM and program the vehicle with ISTA.

Note that ISTA will automatically reprogram and code all programmable control modules that do not have the latest software.

Always connect a BMW-approved battery charger/power supply ( SI B04 23 10  ). 

For information on programming and coding with ISTA, refer to DealerSpeed/TIS/Technical Documentation/Diagnostics and Programming/Programming Documentation.
