Wheel Speed Sensor Faults Cannot Be Cleared

2023-06-14

MODEL
F10 (M5 Sedan) F06 (M6 GranCoupe)F12 (M6 Convertible)F13 (M6 Coupe)
SITUATION
The Dynamic Stability Control (DSC) warning light comes on while driving.
The following DSC fault codes for the wheel speed sensors are stored:
480712
and/or
480715
and/or
480718
and/or
48071B
They cannot be cleared, even though the wheel speed sensors work correctly and no problem can be
found with the wiring harness.
CAUSE
Due to high outside temperatures and extremely low atmospheric humidity, an electrostatic discharge
(ESD) can occur in the wheel well area. This can transfer to the wheel speed sensor, causing
irreparable damage to the DSC control unit.
CORRECTION
Perform the vehicle test with ISTA/D and work through the corresponding DSC test modules. After
completing the applicable test modules, and if DSC fault codes 480712, and/or 480715, and/or
480718, and/or 48071B cannot be cleared, replace the DSC control unit and install ground retrofit kit
P/N 61 13 7 856 494.
Follow the instructions in attachment B340914_ground_cable_retrofit for DSC replacement and kit
installation.

Refer to KSD2

Removing and installing or replacing
DSC control unit (includes removing one
front tire, one front “rear-section”
wheelhouse cover, bleeding the brakes
and connecting an approved battery
charger/power supply)

And:
61 00 730
And:

Refer to KSD2

Programming/encoding control unit(s)

36 10 800

side)

And:
Work time to remove and install both
wheel house covers (front sections),
34 99 000
24 FRU
clean the five contact points and install
ground cable kit.
Labor operation code 00 00 006 is a Main labor operation. If you are using a Main labor code for
another repair, use the Plus code labor operation 00 00 556 instead.
Refer to KSD2 for the corresponding flat rate unit (FRU) allowance. Enter the Chassis Number, which
consists of the last 7 digits of the Vehicle Identification Number (VIN). Click on the “Search” button,
and then enter the applicable flat rate labor operation in the FR code field.
If a control module or component was working properly and/or had no related faults stored prior to
vehicle programming and it fails to program correctly or requires initialization, this additional work
must be claimed with separate labor operations under the defect code listed above; refer to KSD2.
Repairs to control modules and components with pre-existing conditions are not eligible to be claimed
under the defect code listed in this bulletin.
And:
Sublet – Bulk Materials
Reimbursement for the used quantity of
brake fluid (BMW part number 81 22 01
Sublet Code 4

number for claim submission.
Sublet calculation: Reimbursement for the used quantity reimbursement for used quantities of brake
fluid (BMW part number 81 22 01 42 156) at dealer net plus handling.
See sublet
reimbursement
calculation below

Enter this material cost as one sublet amount and itemize each one in the claim comment section.
Other Repairs
If performing other ISTA diagnostics and related test plans results with eligible and covered work,
claim this work with the applicable defect code and labor operations listed in KSD2.

B340914 Ground Cable Retrofit

February 2015

Remove the DSC control unit per RA 34 52 516.

To improve conductivity, clean the
contact area for the DSC bracket
with sandpaper.

Fit the short ground cable from the
retrofit kit.

Remove the wheel arch cover front section for the left front wheel.
Remove the right front wheel and wheel arch cover front section.

B340914 Ground Cable Retrofit

February 2015

Using a suitable tool (flat
countersink), machine the front
contact area to bare metal on both
the left- and right-hand sides of the
body until they are smooth.
This will ensure electrical
conductivity.
Protect the reworked body
attachment points using contact
protection grease (83 19 2 295 229).

Use the existing mounting bolts to
screw the ground cable (750 mm)
from the ESD ground cable set onto
the relevant front wheel speed
sensor (L and R). Torque to 8 Nm.

B340914 Ground Cable Retrofit

February 2015

Route the ground cable along the
wheel-speed sensor cable. Use a
hex bolt (M6x14, 9 905 525) and
a hex nut (M6, 9 915 702) to
screw the other relevant ground
cable end onto the prepared body
attachment point (8 Nm).
Secure it using the cable straps
(1 372 391).

Remove the rear wheels.
Using a suitable tool (flat
countersink), machine the rear
contact area to bare metal on
both the left- and right-hand sides
of the body until they are smooth.
This will ensure electrical
conductivity.
Protect the reworked body
attachment points using contact
protection grease (83 19 2 295
229).

B340914 Ground Cable Retrofit

February 2015

Use the existing mounting bolts to
bolt the ground cable (500 mm)
from the ESD ground cable set
onto the relevant rear wheel
speed sensor (L and R). Torque
to 8 Nm.

Route the ground cable along the
wheel-speed sensor cable. Use a
hex bolt (M6x14, 9 905 525) and
a hex nut (M6, 9 915 702) to
screw the other relevant ground
cable end onto the prepared body
attachment point (torque 8 Nm).
Secure it using the cable straps
(1 372 391).
NOTE: Ensure correct routing in
the marked area; the ground
cables must have sufficient
clearance.

B340914 Ground Cable Retrofit

February 2015

Use an ohmmeter to check that all
of the newly attached ground
cables are working (zero
resistance between the wheel hub
and the vehicle’s ground).

Install the DSC control unit per RA 34 52 516.
