Causes

TV module not fitted (vehicle not equipped)
Blown fuse for TV module power
Poor or missing power supply to the TV module
Poor or missing ground at the TV module
Open or short in data bus wiring (CAN/LIN) to the TV module
Faulty connector or corrosion at module plug

Symptoms

No TV function or display (if fitted)
Related infotainment features may be inoperative
Associated modules throw additional communication-related DTCs
No response from TV module when queried with a scan tool
Intermittent operation or loss of TV on vehicle movement

What to check

Verify vehicle equipment level — confirm whether TV module is installed (service label, factory build sheet, parts list)
Connect a diagnostic scan tool and attempt to communicate with the TV module; note any related U-codes on the network
Inspect fuses and power distribution for TV module circuit
Visually inspect module connector for corrosion, bent pins, water ingress, or poor mating
Check for other modules reporting lost communication on the same data bus
Back-probe module connector (if fitted) for ignition-switched battery voltage and ground presence

Signal parameters

Module supply voltage (key ON): ~11–14 V at module battery/power pin
Ground: near 0 V at module ground pin with key ON
CAN bus idle voltages: CANH ≈ 2.5 V, CANL ≈ 2.5 V (measured to chassis)
CAN bus dominant state: CANH ≈ 3.5 V, CANL ≈ 1.5 V (when traffic is present)
CAN bus differential voltage when active: ~2.0 V
Termination resistance across CANH–CANL (with ignition OFF): ~60 ohms (two 120 Ω terminators in parallel)

Diagnostic algorithm

Confirm code presence and note freeze frame/related codes with a scan tool
Verify vehicle equipment: check factory build sheet, vehicle option codes or physical inspection to confirm if TV module should be present — if not fitted, code may be expected and no repair required
Visually inspect TV module connector and harness for damage, corrosion or disconnection; repair as needed
Check and verify fuses and relays feeding the TV module circuit; replace faulty fuses and retest
With key ON, back-probe power and ground pins at the module connector: verify battery voltage and good ground
Using a multimeter/oscilloscope, measure CANH and CANL at the TV module connector with key ON and while exercising related systems; compare to expected idle and dominant voltages
Measure resistance across CANH–CANL with ignition OFF; expect ~60 Ω. If open or very low, diagnose wiring/terminators
If bus voltages are abnormal, trace wiring toward gateway/BCM looking for opens, shorts to battery/ground, or corrosion; repair wiring and connectors
If wiring and power/ground are good but no communication, attempt to communicate with module from gateway/scan tool; verify coding/configuration — reprogram or reinitialize modules if required
If module still non-responsive after wiring/power/coding checks, replace TV module and re-test communication
Clear codes and road test; monitor for reappearance of B2200 or related network codes

Likely causes

Vehicle not fitted with TV module (expected condition)
Blown fuse or removed power feed to TV module
Disconnected or corroded connector at the TV module
Open/short in CAN or LIN wiring between TV module and gateway
Failed TV module or gateway not addressing the module

Fault status

⚠️ Status

No communication detected with the TV module. Condition may be expected if vehicle is not fitted with TV, otherwise indicates a communication bus, power/ground, connector, or module fault.

🟡 Repair difficulty: Medium

⏱️ Diagnostic time: 0.5-2.5 hours
