What Does B00E8 Mean?
This code indicates a subfault in the deployment control circuit for the third row center seatbelt pretensioner 'C'. The restraint control module has detected an abnormal condition in the pretensioner firing circuit, which could prevent proper deployment during a collision. This is a critical safety system malfunction that requires immediate attention as it may compromise occupant protection in the event of an accident.
Safety Warning
This is a critical safety system fault that compromises third row center occupant protection during a collision. The vehicle should not be driven with passengers in the affected seating position until repaired, as the pretensioner may not deploy properly in an accident.
Common Causes
35%
Faulty seatbelt pretensioner unit with internal circuit failure or resistance out of specification
30%
Damaged or corroded wiring harness between restraint control module and pretensioner connector
20%
Loose or corroded electrical connector at pretensioner or restraint control module
15%
Faulty restraint control module with internal deployment control circuit malfunction
Diagnostic Steps
1
Step 1: Perform visual inspection of third row center seatbelt pretensioner connector for corrosion, damage, or loose connection. Disconnect battery negative terminal and wait 10 minutes before handling any restraint components for safety.
2
Step 2: Using a digital multimeter, measure resistance across pretensioner squib terminals (connector disconnected). Expected reading should be 2-3 ohms typically; consult manufacturer specifications. Readings of 0 ohms (short) or infinite resistance (open) indicate faulty pretensioner.
3
Step 3: Inspect wiring harness from pretensioner to restraint control module for chafing, cuts, pinched wires, or damage. Pay special attention to areas where harness passes through seat tracks or mounting points. Check for proper routing and secure connections.
4
Step 4: Measure continuity and resistance in pretensioner circuit wiring from restraint module connector to pretensioner connector (both disconnected). Each wire should show less than 5 ohms resistance and no shorts to ground or other circuits.
5
Step 5: If all wiring and connections test normal and pretensioner resistance is within specification, suspect restraint control module internal fault. Verify ground connections at module are clean and tight.
6
Step 6: After repairs, reconnect all components, clear codes, and perform restraint system self-test using scan tool. Verify code does not return and all restraint system indicators function normally.
