B00E6 — Third Row Right Seatbelt Pretensioner C Deployment Control Fault

Severity: medium Safe to drive

What B00E6 means

The airbag (SRS) control module continuously tests the squib and pretensioner circuits for opens, shorts and abnormal resistance. B00E6 means it found a fault in the deployment control circuit 'C' of the third row right seatbelt pretensioner. While the fault is active, that pretensioner may not fire in a crash.

Symptoms

  • Airbag / SRS warning light on or flashing
  • Scan tool shows a third row right pretensioner circuit fault
  • Possible loss of proper belt tensioning at that seat in a crash
  • Fault may appear after third row seats were moved, folded or removed

Possible causes

  1. Faulty third row right seatbelt pretensioner (circuit C)
  2. Open or shorted wiring to the pretensioner
  3. Poor connection or corrosion at the pretensioner connector
  4. Harness damaged during seat folding, removal or interior work
  5. Internal fault in the SRS control module (rare)
  6. Generic scanner misreading the code, for example as a hybrid battery fault

How to diagnose

  1. Read all SRS codes with a scan tool that supports airbag systems and save the freeze frame data
  2. Confirm the definition of B00E6 for the specific make to rule out a generic scanner misinterpretation
  3. Inspect the wiring and connectors under the seat and at the third row right belt anchor
  4. Check for pinched harnesses from folding seats or signs of earlier interior repairs
  5. Inspect connector pins for corrosion, spread terminals and a secure latch
  6. Test circuit resistance per the factory wiring diagram, with the battery disconnected and the specified wait time observed
  7. Never probe a pretensioner with a test light or ordinary meter unless the service manual allows it
  8. Clear the code after repair and confirm it does not return

Common fixes

  • Repair the wiring or replace the damaged connector in the pretensioner circuit
  • Replace the third row right seatbelt pretensioner assembly
  • Repair or replace the SRS control module if it is confirmed faulty

Questions and answers

Can I drive with B00E6?

Yes, the car will drive normally because engine and brakes are not affected. But the pretensioner at that seat may not fire in a crash, so don't put off the repair.

What should I do when the SRS light is on?

Read the codes with a scan tool that supports SRS and check the connectors near the third row seat. Work on airbag wiring only with the battery disconnected, or have a shop do it.

Do I need to replace the pretensioner right away?

No, check the wiring and connector first, since a poor connection is a common cause. Replace the pretensioner only if the wiring is good and the fault remains.

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.
