1-Perform a vehicle test with ISTA.
2- Remove the center console as per Repair Instructions 51 16 165 to access the Air Bag Control Module
A11 (ACSM) wiring connector (A11*2B).
Check the ACSM module for signs of corrosion within the electrical connector.
NOTE: The LCI (life cycle impulse, aka “facelift”) models change the design of the ACSM air bag
control module, wire location, connector number. DO NOT FOLLOW THIS BULLETIN FOR LCI
VEHICLES.
3- Follow Repair Instructions 51 45 184 to remove the under-dash trim panel on the driver’s side.
Unplug the connector (B8*1B) on the knee air bag on the driver's side
Cut the knee air bag wiring harness near the connector and tie back the cut wiring with a cable strap
4- Follow Repair Instructions 51 45 195 to remove the under-dash trim panel on the passenger side.
Unplug the connector (B77*1B) on the knee air bag on the passenger’s side

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 air bag control unit connector (A11*2B).
8- Wrap the harness of the knee air bag on the driver's side and passenger's side with an abrasion-resistant fabric
tape (part number 61 13 6 925 452).
9-Follow SI B01 13 23 for the ACSM cover cap if applicable.
