Technical Service

This Service Information bulletin supersedes SI B65 07 15 dated January 2016.
SUBJECT

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

I01 (i3 REx)
I12 (i8)
Vehicles produced up to October 30, 2015
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 switchoff 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
z

Replace the engine harness; or

z

Repair the poor connection at the REME and ACSM4I circuit; and

z

Update the vehicle’s software with ISTA/P V3.57.1 or higher if vehicle I Level is below:

Vehicle

I-Level

I01 (i3 REx)

I001-15-11-501

I12 (i8)

I001-15-11-502

The appropriate correction will be based on the test plan recommendation.
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

https://www.bmwtis.net/tiscode/cgi-bin/bulletin.aspx?sie_path=/tsb/bulletins/htm_store/308... 3/3/2016

Page 2 of 5

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 question should appear in ISTA: “Has the line between the last
intermediate connector and the range extender electric machine (REME) already been
replaced?”
Follow step 3.
3. Review the repair history and if the answer is NO, the engine harness needs to be
replaced.
If the test recommendation is for repairing the connectors. Follow the next steps:
4. 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.
5. Refer to REP 1251040 “Removing and installing/replacing wiring harness section for range
extender electrical machine electronics (REME) (I01)”
6. **NOTE - For vehicles produced up to 8/2015 - once parts stock of the 12 51 7 636 973
harness is depleted, you will use the later production harness 12 51 8 653 789. This harness
incorporates an additional white plastic holder which must be bolted to the side of the REME
using the heat shield and screw listed below. Torque heatshield screw to 11.8 Nm
For i8 vehicles that have the same fault, perform the following steps:
1. Refer to the ISTA test plan recommendation. Review wiring diagram SP0000057786 and
check the connector and connections. Check A11*2B, X558*6B, and A270*1B for this
circuit, or refer to the wiring diagram.
2. Refer to REP 1243001 “Removing and installing/replacing the high voltage cable for starter
motor generator (I12)”
If the engine harness “has been previously replaced” after performing this bulletin and
vehicle returns because this same fault code is stored, please submit a PuMA case for further
technical support.
