Suspension Control Module - Data Erroneous
The suspension control module has detected faulty data from a sensor.
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 in your truck that controls the suspension sees data from a sensor that doesn't make sense; it's like getting an impossibly high temperature reading from a thermometer.
What the computer is actually seeing
The suspension control module expects sensor input like vehicle height or pressure within defined ranges. If the input is outside expected limits (for instance, a height reading over 10 inches in a low-rider truck), it triggers this code.
What a healthy reading looks like
Expected values vary by suspension setup but typically should show height readings around 5-10 inches from the ground on air suspension systems during normal operation.
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.
- 11. Check the wiring and connectors to the suspension sensor for damage or corrosion. Repair or replace as necessary. Decision point: If you're good here, move to step 2.
- 22. Inspect the suspension sensor itself for faults or physical damage. Use a multimeter to check resistance based on specs. Decision point: If sensor is faulty, replace it, else move to step 3.
- 33. Verify the suspension control module is properly calibrated. Consult manufacturer specs for calibration procedure. Decision point: If recalibration doesn't resolve the issue, consider replacing the module.
Common causes
- Faulty suspension sensor
- Wiring issues or bad connectors
- Corrosion at the connector terminals
- Calibration errors in the suspension control module

Frequently asked questions
Can I still drive with this code?
Yes, but the truck may have reduced suspension performance and handling could be compromised.
Will this code come back after I clear it?
If the underlying issue isn't fixed, it's likely to return.
Does this code relate to the ABS system?
Not directly, but issues with suspension can sometimes affect traction and ABS performance.
