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

About P1210

P1210 is a manufacturer-specific powertrain diagnostic trouble code recorded for Infiniti 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

The traction control system reduces engine torque when wheel slip is detected, and it communicates with the Engine Control Module (ECM) through a torque reduction signal circuit. On these Nissan and Infiniti vehicles, DTC P1210 sets when the ECM detects a fault in the traction control signal circuit, meaning the signal exchanged between the traction control or ABS control unit and the ECM is missing, out of range or implausible. The cause is usually wiring or connector related, or a fault in one of the control units sharing the circuit. Symptoms can include a disabled or warning lit traction c...
