Q: My Nissan speedometer is frozen and I have U0073 — is it the connector?
A: U0073 (CAN bus off) with a frozen speedometer on Nissan vehicles is frequently caused by corrosion on the CAN High/Low pins (Pins 4–5) in the 6-pin cluster connector. Inspect the connector before replacing the instrument cluster or ECM.
Q: Are terminals included?
