B00E2 — Third Row Center Seatbelt Pretensioner B Deployment Control Fault

Severity: medium Safe to drive

What B00E2 means

The restraint control module found a problem in the circuit that fires pretensioner B on the third row center seatbelt. The module regularly tests the resistance and continuity of its squib circuits. If readings fall outside the expected range, it stores this code and may disable that restraint.

Symptoms

  • Airbag (SRS) or seatbelt warning light is on
  • B00E2 stored in the restraint module
  • Possible third row belt fault noted in scan data
  • Engine and transmission behave normally

Possible causes

  1. Faulty third row center seatbelt pretensioner B
  2. Open or shorted wiring in the pretensioner circuit
  3. Poor connection or corrosion at the pretensioner connector
  4. Harness damage under the trim or seat (pinching, chafing, moisture)
  5. Rarely, a failed restraint control module

How to diagnose

  1. Scan the SRS module and record all stored codes, not only B00E2
  2. Inspect the belt, connector and harness in the third row for moisture, pinching, or seat-removal damage
  3. Check that the connector is fully latched and the terminals are clean and not bent
  4. Disconnect the battery and wait the time specified by the manufacturer before touching SRS circuits
  5. Measure circuit resistance per service data, never applying voltage to the squib
  6. Test the circuit for shorts to ground and to power
  7. Clear the code and see if it returns

Common fixes

  • Clean and secure the connectors in the circuit
  • Repair or replace damaged wiring and connectors
  • Replace the third row center seatbelt pretensioner B
  • Replace the restraint control module if it is confirmed faulty

Questions and answers

What does B00E2 mean?

The restraint module detected a fault in the control circuit of pretensioner B on the third row center seatbelt. The cause may be the pretensioner, wiring or a connector.

Can I drive with code B00E2?

Yes, it does not affect how the car drives. But that belt's pretensioner may not work in a crash, so have it checked soon.

Can I test the pretensioner circuit myself?

You can visually inspect connectors and wiring. Electrical testing of SRS circuits is risky without disconnecting the battery and proper knowledge, because of accidental deployment. A qualified technician should do it.

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.
