Invalid Data Received from Vehicle Speed Control Module
The vehicle's speed control module is sending invalid data to the engine control module.
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 computer that controls your speed isn't sending accurate information, which can affect your speedometer and cruise control.
What the computer is actually seeing
The Engine Control Module (ECM) sees an unexpected message or data from the speed control module, indicating a communication error, often flagged after a series of message timeouts or error checks.
What a healthy reading looks like
The vehicle speed should typically be between 0 and 160 mph (0 to 256 km/h). Any reading outside this range is suspect. The ECM expects valid speed data every 20-50 milliseconds.
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.
- 1Check for any visible damage to wiring and connectors related to the speed control module. Ensure connections are tight and free of corrosion.
- 2Scan for additional codes that may point to related issues, especially in the speed control or ABS systems. If other codes are present, address them before proceeding.
- 3Using a multimeter, check voltage at the speed control module connector. You should see about 5V power supply. If not, trace back to the ECM or fuse.
- 4Test the speed control module by monitoring data with a scan tool while driving. Look for live data values. If the speed reading is erratic or stays at 0 while the vehicle is moving, module may be faulty.
Common causes
- Faulty speed control module
- Damaged wiring or connectors
- ECM software error
- Poor ground connection
- Other related module failures

Frequently asked questions
Is it safe to drive with this code?
It's generally drivable but may affect cruise control and speedometer accuracy. Fix soon.
Will the code come back?
If the underlying issue isn't resolved, yes, the code will likely return after clearing it.
Why does this code pair with others?
Multiple codes may indicate a broader communication issue among modules, often stemming from a common wiring problem.
