SITUATION
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 midJanuary 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.
