Q: What does code P1697 mean?

Traction Control Fuel Cut Signal High Input. P1697 on Nissan vehicles means the engine control module (ECM) has detected a high-voltage condition on the traction control fuel cut signal circuit, which is the wire the ECM uses to request a temporary fuel cut from the traction control system during wheel slip. The ECM expects a specific voltage range on this signal line, and a reading above that range tells the computer the circuit is shorted to power or the signal is otherwise stuck high.
