Frequently Asked Questions

What does a low signal in the run circuit mean?

The voltage on the ignition run wire is lower than expected, often from a short to ground, high-resistance connection, or failed switch contacts.

Can steering column work cause P2532?

Yes. If the steering column was recently serviced, a connector may not have been fully seated, causing a poor connection in the ignition circuit.

Is P2532 related to a recall?

Several manufacturers have had ignition switch recalls. Check with your dealer or the NHTSA recall database to see if your vehicle is affected.
