What it means
A receiving module detected implausible data from restraints system sensor E (satellite crash sensor). Acceleration profile values fail plausibility checks against other crash sensors and are rejected.
At a glance
- Usually lights the warning light of the system that lost communication
How it works
Restraints system sensor E is a satellite crash sensor that reports acceleration data to the restraint control system and other vehicle modules. This code sets when a receiving module judges sensor E's reported crash profile implausible compared with data from the other crash sensors and rejects it.
Common causes
Most likely first.
- Module internal fault or sensor input drift
- Software version mismatch after replacement
- Gateway module routing CAN messages incorrectly
Symptoms
- Multiple warning lights may illuminate
- Affected modules may go into limp mode or shut down
- Specific functions inoperative depending on module
- Diagnostic tools may show communication faults
How to diagnose it
- Record freeze-frame data and scan all modules for related restraint and communication codes to identify when the sensor E data was rejected and which modules were affected.
- Use a capable scan tool to compare live data for sensor E with the other crash sensors and check whether the implausible reading is current or intermittent.
- Inspect sensor E's connector and accessible wiring for damage, corrosion, loose terminals, or signs of impact or water intrusion.
- Check for recent restraint-module, sensor, or gateway replacement and verify that the installed software and configuration are compatible with the vehicle.
- Have a qualified technician test the sensor E input, its power and ground if applicable, and the relevant network messages against the manufacturer's specifications.
Common fixes
- Repair a loose, corroded, or damaged sensor E connector or wiring.
- Restore the correct compatible software or configuration after a module or sensor replacement.
- Repair a gateway or network-routing fault that is disrupting sensor E data.
- Replace sensor E if testing confirms its output is drifting or implausible.
- Replace the receiving restraint module if its input circuitry is confirmed faulty.
Can I keep driving?
Treat the restraint system as potentially impaired: airbags or related protections may not work as intended, even if the vehicle drives normally. Avoid unnecessary driving and have the fault diagnosed promptly; do not probe or disconnect restraint-system components yourself.
A code shows where the control module detected a fault, not always which part failed. Check the causes in order and confirm with a test before replacing parts. Have several codes? Check them together
This is a generic code: it means the same on every make. The car’s maker may add more detail in its own service information.
