SITUATION
A check control message (CCM) for the restraint system (Air bag) appears. In the instrument cluster, the red
air bag warning light lights up permanently.
One of the following fault codes is stored in the ACSM (air bag control unit):
930949 - Knee airbag, driver: short circuit to negative terminal
93094F - Knee airbag, front passenger: short circuit to negative terminal
93094C - Knee airbag driver's side: Resistance too great
930952 - Knee airbag, front passenger: Resistance too great

CAUSE
Over time, the wiring harness going to the knee air bag(s) can rub against the metal support tubes for the
instrument panel, chafing and damaging the wiring.

CORRECTION
Remove the center console to access the ACSM control module.
Remove the under-dash trim panels on both the driver’s and passenger’s sides.
This gives sufficient access to perform this repair.
The dashboard cover does not need to be removed.
The knee air bags do not need to be removed.

location.

8- Unplug the wiring connector from the ACSM (A11*2B).
Reference Wiring Diagram ‘Airbag firing circuits’ SP0000061332 and confirm the wire color and pin
number BEFORE cutting these 4 wires at the ACSM connector.
9- Cut the 4 wires for the knee air bag wiring harnesses near the ACSM connector and tie back the 4 cut
wires with a cable strap.
ACSM Pin 25 (A11*2B) goes to pin 1 of driver knee air bag (B8*1B).
ACSM Pin 20 (A11*2B) goes to pin 2 of driver knee air bag (B8*1B).
ACSM Pin 5 (A11*2B) goes to pin 1 of passenger knee air bag (B77*1B).
ACSM Pin 10 (A11*2B) goes to pin 2 of passenger knee air bag (B77*1B).
Then pin 2 repair cables into the airbag control unit connector (A11*2B).
Wrap the knee wiring harnesses with an abrasion-resistant fabric tape (part number 61 13 6 925 452).
Route one repair harness to the knee airbag on the driver's side and the other to the knee air bag on the
