What Does B00E5 Mean?
This code indicates a fault in the deployment control circuit for the second row center seatbelt pretensioner 'C'. The Restraint Control Module (RCM) or Body Control Module (BCM) has detected an abnormal electrical condition in the pretensioner firing circuit, such as high resistance, low resistance, open circuit, or short circuit. This subfault designation suggests a secondary or component-level issue within the pretensioner deployment system that prevents proper operation during a collision event.
Safety Warning
This is a critical safety system fault. The second row center seatbelt pretensioner will NOT deploy in a collision, significantly increasing injury risk to the occupant. The vehicle should not be driven with passengers in this seating position until repaired, and the SRS warning lamp will remain illuminated.
Common Causes
45%
Faulty seatbelt pretensioner unit with internal circuit failure or damaged squib
30%
Damaged, corroded, or disconnected wiring harness or connector between RCM and pretensioner
15%
Corroded or loose pretensioner connector terminals causing high resistance
10%
Faulty Restraint Control Module with internal deployment circuit malfunction
Diagnostic Steps
1
Step 1: Visually inspect the second row center seatbelt pretensioner connector for corrosion, damage, moisture, or loose connection. Disconnect and examine both male and female connector terminals for bent pins or green corrosion.
2
Step 2: Measure resistance across the pretensioner squib terminals (typically 2-3 ohms nominal). Disconnect pretensioner connector at both ends and verify squib resistance is within manufacturer specification (usually 1.5-4.0 ohms).
3
Step 3: Check wiring harness continuity from pretensioner connector to RCM connector using a multimeter. Verify less than 1 ohm resistance on both deployment circuit wires and confirm no short to ground or short to power (should read infinite resistance).
4
Step 4: If wiring and pretensioner resistance are correct, inspect RCM connector for corrosion or damage. Clear codes and monitor for recurrence to determine if RCM internal circuit is faulty.
5
Step 5: After repairs, use scan tool to command system self-test (if available) and verify no DTCs return. Perform final verification by cycling ignition and confirming airbag/SRS warning lamp extinguishes properly.
