No Communication With Traffic MasterModule

Where it lives

For B2201, the part to look at first is the module named here.

Check these first

• A VIN in the powertrain control module that does not match the occupant restraint controller
• A failed occupant restraint controller
• An open or short in the occupant restraint controller wiring
• A poor electrical connection at the occupant restraint controller

What to do next

1. Read the VIN in the powertrain control module and occupant restraint controller
2. Check the occupant restraint controller power and ground
3. Inspect the occupant restraint controller connector and wiring
4. Program the correct VIN if the modules disagree
5. Replace the occupant restraint controller if it stays offline
6. Clear the code and retest
