Invalid Configuration Data

The control module has detected invalid data in its configuration.

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)

The vehicle's computer is seeing data that doesn't match what it expects from the systems. This could be due to a setting being off or a module not communicating properly.

What the computer is actually seeing

The control module sees inconsistent or out-of-range values from a sensor or another module, indicating a fault in configuration.

What a healthy reading looks like

Look for voltage values between 0-5 volts from sensors; configuration values should match factory settings.

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 all related wiring and connectors for damage or loose connections. Repair as needed. Decision: Are connections intact? -> Go to step 2 if yes.
  2. 22. Verify that all control modules have the latest software updates. Flash if necessary. Decision: Did the update resolve the issue? -> If yes, code is cleared. If no, go to step 3.
  3. 33. Inspect the configuration data of the control module using a scan tool; ensure it matches spec. Decision: Is the data consistent with specifications? -> If yes, replace the control module. If no, correct the data accordingly.

Common causes

  • Faulty control module
  • Electrical connector issues
  • Software updates needed
  • Mismatched sensor configurations
  • Wiring harness damage
