What Does B00E6 Mean?
This code indicates the Body Control Module (BCM) has detected a subfault in the deployment control circuit for the third row right seatbelt pretensioner circuit C. The pretensioner system is designed to retract the seatbelt during a collision to secure occupants, and this fault suggests an electrical issue in the deployment circuit that prevents proper operation or monitoring. The BCM has identified an abnormality in the circuit's resistance, continuity, or voltage that could prevent deployment during a crash event.
Safety Warning
This is a critical safety issue. The seatbelt pretensioner in the third row right position will not function during a collision, significantly increasing injury risk to that occupant. Vehicle should not be occupied in this seating position until repair is completed, and repair should be performed immediately by a qualified technician.
Common Causes
35%
Faulty seatbelt pretensioner unit or internal circuit failure in the pretensioner initiator
30%
Damaged or corroded wiring harness or connector between BCM and pretensioner
20%
High resistance or open circuit in pretensioner deployment loop
15%
Body Control Module internal fault or software corruption
Diagnostic Steps
1
Step 1: Visually inspect the third row right seatbelt pretensioner connector for corrosion, bent pins, moisture intrusion, or damage. Check that connector is fully seated and locked.
2
Step 2: Using a multimeter, measure resistance across the pretensioner deployment circuit terminals (typically 2-5 ohms for most pretensioners). Compare reading to manufacturer specifications to verify pretensioner integrity.
3
Step 3: Inspect wiring harness from BCM to pretensioner for chafing, cuts, pinch points, or signs of previous repair. Pay special attention to routing through seat mounting points and folding mechanisms.
4
Step 4: Check ground circuit continuity between pretensioner ground and body/chassis ground using multimeter (should be less than 1 ohm resistance).
5
Step 5: If all wiring and pretensioner resistance checks are within specification, perform BCM voltage supply test to pretensioner circuit (typically 12V reference) to rule out BCM internal failure.
6
Step 6: Clear codes and perform system retest. If code returns immediately without vehicle movement, replace pretensioner assembly. If code does not return, monitor for intermittent connection issues.
