U0559 — Invalid Data Received From Radio Transceiver

How much does it cost to fix U0559?

Repair CAN wiring or connectors — $100–$400; Remove interfering aftermarket device — $0–$150; Replace the faulty control module — $300–$1,500. Exact cost depends on the root cause, your vehicle and local labor rates — a proper diagnosis is the cheapest first step.

Will U0559 clear itself?

Sometimes U0559 clears after a few drive cycles if the fault was intermittent — for example a loose connector or a tank of bad fuel. The underlying cause usually remains, so the code tends to return. Clear it once; if it comes back, diagnose rather than erase it repeatedly.

What does OBD2 code U0559 mean?

Invalid Data Received From Radio Transceiver (U0559): a vehicle network fault affecting the vehicle network (CAN bus) communication. Short, gentle driving to a shop is usually possible. Most often caused by water ingress in harness junctions, a faulty module pulling the bus down, aftermarket equipment interfering with the bus.

What are the symptoms of U0559?

Drivers most often notice: no-start or intermittent starting in some cases, multiple warning lights on at once, random, hard-to-reproduce electrical glitches, intermittent loss of functions (gauges, windows, steering assist).

How do I diagnose U0559 myself?

Start with a scan: confirm U0559, save the freeze frame and note any companion codes. Then inspect the wiring and connectors related to the vehicle network (CAN bus) communication, and verify the suspect component against live data before buying parts.

What does U0559 mean?

When U0559 appears on a scan, it means the control module has flagged a problem in the vehicle network (CAN bus) communication: invalid data received from radio transceiver. The fault sits in the vehicle network group of the OBD2 standard.

This code does not appear from a single bad reading: the module must see the fault condition repeat under defined operating conditions before it turns on the warning light. The freeze frame captured with U0559 — engine load, rpm, temperature, speed — tells you exactly when the problem occurs, so reproduce those conditions when testing.

Common symptoms of U0559

• no-start or intermittent starting in some cases
• multiple warning lights on at once
• random, hard-to-reproduce electrical glitches
• intermittent loss of functions (gauges, windows, steering assist)
• modules intermittently not communicating with the scanner

What causes U0559?

• damaged CAN bus wiring or short to power/ground
• water ingress in harness junctions
• corroded connectors, especially in wet areas
• aftermarket equipment interfering with the bus
• a faulty module pulling the bus down

How to diagnose U0559

1. Connect an OBD2 scanner, confirm U0559 is stored, and save the freeze frame data — it shows engine conditions when the fault was detected.
2. Related codes often reveal the real root cause. Also check manufacturer technical service bulletins (TSB) for your make and model — many U0xxx issues have factory fixes or software updates. Search by VIN on the manufacturer site or nhtsa.gov.
3. Visually inspect the wiring harness and connectors related to the vehicle network (CAN bus) communication for damage, corrosion, chafing or poor contact.
4. Measure resistance between CAN-High and CAN-Low at the OBD port with power off — about 60 Ω is healthy.
5. Scan all modules: the one that does not respond is either the culprit or downstream of the break.
6. Clear the code, complete a full drive cycle including the conditions from the freeze frame, and confirm U0559 does not return.

How to fix U0559

Start with the cheapest and most common causes before replacing expensive parts:

• Repair CAN wiring or connectors — $100–$400
• Remove interfering aftermarket device — $0–$150
• Replace the faulty control module — $300–$1,500

How much does it cost to fix U0559?

Repair cost depends on which component actually failed. Typical scenarios for U0559 (parts and labor, USD, independent shop rates):

• Repair CAN wiring or connectors: $100–$400
• Remove interfering aftermarket device: $0–$150
• Replace the faulty control module: $300–$1,500

Overall, fixing U0559 usually costs between $0 and $1,500. An accurate diagnosis before buying parts saves money — the most expensive scenario is rarely the first one to check.

Can you drive with U0559?

Depends on what is affected. A single dead convenience module is fine to drive with; loss of communication with engine, braking or steering modules is not. If multiple critical systems drop out, do not drive.
