B00E8 — Third Row Center Seatbelt Pretensioner C Deployment Control Fault
What B00E8 means
The airbag (SRS) control module constantly tests the squib circuits, including the pretensioner for the third row center seatbelt (circuit C). B00E8 means the circuit's resistance or voltage is out of range, or the module received an invalid signal. While the fault is active, the restraint system may not work properly in a crash.
Symptoms
- Airbag / SRS warning light on
- B00E8 stored in the SRS module
- Other SRS circuit faults may appear if a shared connector or the module is at fault
Possible causes
- Failed third row center seatbelt pretensioner C
- Open or shorted pretensioner wiring
- Poor connection, corrosion or damaged connector under the seat or trim
- Communication error between the SRS module and other modules (occupant sensor, body module)
- Faulty SRS module (rare)
How to diagnose
- Scan all modules with a tool that reads SRS codes and save the freeze-frame data
- Check for other SRS or network codes and address those first
- Inspect the connector and harness near the third row belt for water, corrosion, chafing or cargo damage
- Confirm connectors are fully seated and terminals are clean
- With the battery disconnected and the wait time observed, test circuit continuity per the wiring diagram; never apply voltage to a squib
- Measure circuit resistance with the proper tool or scan data
- Swap in a known-good pretensioner or approved tester if the service manual allows
- Clear the code and confirm it doesn't return
Common fixes
- Repair the wiring or replace the damaged connector
- Clean and secure connector terminals
- Replace the third row center seatbelt pretensioner
- Reprogram or reset the SRS / body module per procedure
- Replace the SRS module if the fault is confirmed there
Questions and answers
What does B00E8 mean?
The SRS module detected a fault in the control circuit of pretensioner C on the third row center seatbelt. It is a safety restraint code, not an engine one.
Is it safe to drive with the SRS light on?
You can drive, but the pretensioner or airbags may not deploy in a crash. Have it diagnosed as soon as possible.
Can I fix B00E8 myself?
You can inspect the connector and harness with the battery disconnected. Replacing the pretensioner or handling squibs is best left to a shop because of accidental deployment risk.
This is general information about the code. The meaning can differ between makes and models: a scan tool and the repair manual for your car will show the exact cause.
