What Does B2200 Mean?
This diagnostic trouble code indicates that the Body Control Module (BCM) or infotainment system has detected a loss of communication with the Television (TV) module or that no TV module is installed in the vehicle. The communication failure occurs over the vehicle's internal communication network (typically CAN bus or MOST bus). This code is commonly set in vehicles equipped with or pre-wired for rear-seat entertainment systems when the TV module is either missing, disconnected, or has failed.
Common Causes
35%
TV module not installed or removed from vehicle equipped with rear entertainment pre-wiring
30%
Damaged or disconnected wiring harness between BCM and TV module connector
20%
Failed TV module internal circuit board or communication chip
10%
Blown fuse or lost power supply to TV module preventing communication initialization
5%
BCM software configuration issue or corrupted module addressing
Diagnostic Steps
1
Step 1: Verify if vehicle is equipped with a TV/rear entertainment module by checking physical installation locations (typically overhead console, seatback, or cargo area) and confirm module presence and secure connector engagement
2
Step 2: Check all related fuses in fuse box for TV module, rear entertainment system, and infotainment power supplies using a test light or multimeter, replacing any blown fuses found
3
Step 3: Inspect TV module connector and communication harness for physical damage, corrosion, pushed-back pins, or water intrusion; measure voltage at TV module power pins (should have battery voltage and ground)
4
Step 4: Using diagnostic scan tool, attempt to communicate directly with TV module and check for module addressing/configuration; verify CAN bus or MOST bus communication lines for proper resistance (typically 60 ohms CAN, 20-40 ohms MOST)
5
Step 5: If vehicle was not equipped with TV module from factory, check BCM coding/configuration to disable TV module monitoring, or install proper TV module if feature is desired
6
Step 6: Clear codes, cycle ignition, and verify repair by confirming communication is established with TV module and code does not return
Estimated Repair Cost

The most common cause of B2200 (No Communication to TV Module (No Fitting of TV)) is: TV module not installed or removed from vehicle equipped with rear entertainment pre-wiring
Typical repair costs for B2200 range from $100 to $800, depending on the vehicle, location, and whether you do it yourself or go to a shop.
This code does not affect vehicle safety or driveability and the vehicle is safe to operate normally. This is purely a convenience feature related to rear-seat entertainment and can be addressed at the owner's convenience.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to B2200 to identify the root cause.
