SUBJECT

Airbag Warning Light ON: Fault 930BE8, High-voltage System Shutdown
MODEL

I01 (i3 REx)
I12 (i8)
SITUATION

The airbag warning light in the instrument cluster is on, or the check control message (CCM) “Restraint
system faulty” is displayed.
The advance crash safety module (ACSM4I) has fault code 930BE8 “High-voltage system switch-off Range
extender Electrical Machine Electronics (REME)/battery management electronics: Resistance too high”
stored.
CAUSE

A sporadically poor connection causes high resistance in the airbag ignition circuit.
CORRECTION

• Refer to the test plan recommendation to replace the engine harness.
• Refer to the test recommendation to repair the poor connection at the REME and ACSM4I circuit.
PROCEDURE

Warning!
Only properly trained personnel, who have passed all applicable technical training courses, should
perform any maintenance or repairs on any Hybrid or Electric Vehicle. Work performed by
unqualified persons may result in severe injury or damage to the vehicle. Additional information may
be found in REP 61 00… Observe safety instructions when handling electric vehicles.
1. Diagnose the vehicle with ISTA. Follow the test plan ABL-DIT-Ignition circuits, or follow this path:
Function Structure / 03 Body / Safety functions / Ignition circuits. The test plan is for any airbag
ignition circuits. The resistance reading will be displayed and shows OK (sporadic fault).
2. The following this question should appear in ISTA: “Has the line between the last intermediate
connector and the range extender electric machine (REME) already been replaced?” Follow steps 3 and
4.
3. Review the repair history and if the answer is NO, the engine harness needs to be replaced.
4. Follow the procedure described in the attachment SI B65 03 15_I01_Replace_Engine_harness.pdf.
The test recommendation is for repairing the connectors. Follow the next steps:
5. Refer to ISTA for repairing the connectors; review the wiring diagram SP0000056895 and check the
connections. Check A11*1B, X558*2B, X13*2B, and A274*1B for this circuit, or refer to the wiring
diagram.
6. Follow the procedure described in the attachment SI B65 03 15_I01_Repair_Procedure.pdf to
determine the locations for control units and connectors.
