Steering Control Module Power Loss

The steering control module has detected a power loss.

Heads up: this code wasn't in our hand-written library yet, so DiagCoach AI built this page on the fly. Double-check critical specs against service info before condemning parts.

What it means (plain English)

Your steering control module isn't getting the power it needs to function, which can affect your steering system.

What the computer is actually seeing

The steering control module monitors its own voltage and signals. If it sees a drop below 9 volts while powered, it triggers this code.

What a healthy reading looks like

Steering control module should have a voltage input between 10-16 volts while the vehicle is on.

Guided diagnostic — the DiagCoach way

Don't just throw parts at it. Walk through these in order — each step tells you whether to keep going or stop and fix what you found.

  1. 11. Check the battery voltage at rest and while running; it should be above 12.4 volts.
  2. 22. Inspect and clean the battery terminals and connections; ensure they are tight and free of corrosion.
  3. 33. Check the wiring and connectors leading to the steering control module for damage or signs of shorts.
  4. 44. With a multimeter, measure the voltage at the steering control module connector with the key on; it should be between 10-16 volts.
  5. 55. If voltage is fine, use a scan tool to check for any additional codes that may indicate other issues.
  6. 66. If all else checks out, consider testing or swapping the steering control module.

Common causes

  • Bad battery connection
  • Faulty wiring or connectors
  • Failed steering control module

Will this code come back after clearing it?

It might if the underlying issue isn't fixed.

What if it pairs with other codes?

That could indicate a more complex issue with the steering or electrical systems.
