P1572 — Cruise control brake switch circuit fault

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

About P1572

P1572 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 P1572 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.

P1572 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 cruise control brake switch on Nissan vehicles signals to the ASCD or cruise control system when the brake pedal is pressed so cruise control is cancelled for safety. Many systems use two brake switch inputs, a normally open stop lamp switch and a normally closed ASCD brake switch, and the control module compares them for agreement. DTC P1572 sets when the module detects a fault or implausible combination in the cruise control brake switch circuit, such as both inputs indicating the same state or a circuit open or short. Symptoms include cruise control that will not set or that cancels une...
