Causes

Open circuit in pretensioner squib wiring (broken conductor, chafed harness)
Short to ground or short to battery voltage on the pretensioner circuit
Corroded, loose or damaged connector at the pretensioner or RCM
Failed pretensioner squib (pyrotechnic element) with incorrect resistance
Faulty restraint control module (RCM) or internal driver transistor
Water intrusion or contamination in seat, connector or harness

Symptoms

SRS / airbag warning lamp illuminated on instrument panel
Seat belt pretensioner or supplemental restraint system message displayed (if equipped)
Affected pretensioner is disabled (won't arm or will not deploy)
Stored DTC B00E5 (may be accompanied by other SRS codes)
Possible disablement of related safety restraint functions

What to check

Use a compatible scan tool to read all stored SRS codes and freeze frame data
Verify battery voltage is within normal range; unstable voltage can affect diagnostics
Visually inspect second-row center seat, connectors and wiring for damage, corrosion or water ingress
Confirm whether vehicle has had prior deployment and repairs — check repair history and squib replacement records
Check for related SRS codes that may point to common faults or module communication errors

Signal parameters

Pretensioner squib resistance (typical range for many squibs): about 0.5–3.0 ohms (refer to OEM spec)
Open-circuit indication: infinite/OL resistance between squib terminals
Short-to-power: near 0 ohms to battery positive (with power disconnected)
Short-to-ground: near 0 ohms to chassis ground (with power disconnected)
RCM command voltage during deployment: battery voltage level on deployment line (observed only during deployment test — use OEM procedures)
Scan tool data: DTC count, event/impact data and freeze frame timestamp

Diagnostic algorithm

Read and record all SRS/RCM codes and freeze frame data with a capable scan tool.
Verify vehicle battery state and charging system; restore correct battery voltage if low.
Perform a visual inspection of the second-row center seat area, harness, connectors and floor for damage, corrosion or water intrusion. Repair or replace damaged wiring/connectors as needed.
Before any squib measurements, follow OEM SRS safety procedures: disconnect battery negative terminal and wait the manufacturer-specified time (commonly 2–10 minutes) to disable the airbag system.
Measure resistance across the pretensioner squib terminals at the seat connector with wiring connected/disconnected as required. Compare to OEM specification; an open or out-of-range resistance indicates a faulty squib or wiring fault.
Check continuity from the pretensioner connector to the RCM connector for opens or high resistance. Check for unintended continuity to ground or to battery positive (shorts).
Inspect and test the connector pins for corrosion, bent pins or poor contact; repair or replace connector as required.
If wiring and connector are good and squib resistance is within spec, check RCM outputs and related circuitry per OEM procedures (some tests require specialized tools and OEM diagnostic steps).
If a deployment has previously occurred, confirm that the pretensioner was replaced with correct OEM part and that harnesses/connectors were restored correctly.
Repair or replace defective component(s): wiring repair, connector replacement, pretensioner squib replacement, or RCM replacement only after confirming root cause. Follow OEM torque, routing and safety requirements.
Clear codes with scan tool and perform SRS system self-check and test drive or simulated checks according to service manual. Verify code does not return.
If code returns or diagnosis is uncertain, consult OEM service information for module programming, module-to-module communication checks, or advanced diagnostics.

Likely causes

Open or high resistance in squib/harness at seat connector
Short to ground on the pretensioner deployment line
Corroded/loose connector at the pretensioner or RCM
Failed pretensioner squib

Fault status

⚠️ Status

Restraint Control Module detected a fault in the second-row center seat belt pretensioner C deployment circuit (open/short/out-of-range or communication error). Pretensioner may be disabled until repaired.

🔴 Repair difficulty: Hard
