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
