P1210 — Traction Control Signal Circuit

System: Powertrain  |  Type: Manufacturer-Specific  |  Make: Nissan

About P1210

P1210 is a manufacturer-specific powertrain diagnostic trouble code recorded for Nissan vehicles. It belongs to the P-prefix family of codes, which covers engine, transmission, emissions, or fuel-system faults.

When P1210 is stored, the module has detected an electrical-circuit fault in the wiring, connector, or driver associated with the named component.

Scanning & clearing: A generic OBD-II scan tool will usually read and clear powertrain (P) codes. For live data, freeze-frame capture, and bi-directional tests you may need a more capable scan tool that supports the vehicle's ECM protocol.

P1210 is a manufacturer-specific code. The same code string on a different make may have a different meaning. Always confirm the code's definition against the vehicle's service information for the specific make and model under test.

Code Information

On vehicles with traction control, the traction control or ABS control unit sends a signal to the Engine Control Module (ECM) requesting engine torque reduction when it detects wheel slip during acceleration. DTC P1210 is set when the ECM detects a fault in this traction control signal circuit, meaning the signal it receives from the traction control system is missing, out of range or implausible. The fault usually lies in the wiring between the traction control or ABS unit and the ECM, in the connectors, or in the controlling module itself. Depending on the design this circuit may be a dedica...
