P2534 Code: Ignition Switch Run/Start Position Circuit Low

Various modules in your vehicle control specific components and functions in your vehicle. They use sensor input and collaborate to control a variety of outputs. The modules must receive power from the battery when the ignition switch is in the run or start position.  When there’s a voltage supply issue, one of the modules could log code P2534.

What Does the P2534 Code Mean?

Diagnostic trouble code (DTC) P2534 stands for “Ignition Switch Run/Start Position Circuit Low.” The code is set once a module detects a voltage that’s below the manufacturer-specified value.

When you turn on your ignition, battery voltage is automatically sent to all the electrical systems in your vehicle. If the circuit signal falls below the specified voltage range, it’ll trigger the P2534 code.

Code P2534 requires immediate attention. So if your vehicle logs this code, take measures to resolve the issue right away.

Note: The definition of code P2534 can differ depending on the vehicle manufacturer. Check the appropriate repair manual or repair database for the exact code definition.
