Causes

Open, shorted, or corroded wiring to the recline position sensor
Poor or intermittent connector contact at the sensor or seat module
Failed/recalibrated recline position sensor (potentiometer or hall-effect)
Mechanical binding or damage to the recline mechanism preventing sensor movement
Faulty seat control or occupant detection module (seat ECU)
Water ingress or contamination of seat harness or sensor

Symptoms

Airbag or SRS warning lamp illuminated
Memory seat or seat position functions may not operate correctly
Occupant detection / restraint deployment logic altered or disabled
Stored B00C6 and possibly related seat/airbag codes
Possible inability to calibrate or store seat memory positions

What to check

Use a scan tool to read and record B00C6 and any related codes and freeze-frame data
Check for other restraint or occupant classification codes that may point to related faults
Visually inspect seat underside, hinge area and wiring harness for chafing, breaks, or water damage
Inspect connectors at the recline sensor and seat module for corrosion, bent pins, or loose terminals
Verify battery voltage and good ground; low system voltage can cause sensor faults
Measure sensor supply and ground at the connector with ignition ON (do not deploy airbags during testing)

Signal parameters

Typical sensor type: variable resistor (potentiometer) or hall-effect angle sensor
Common supply voltage: 5 V reference (some systems use ignition/switched 12 V) — verify with vehicle wiring diagram
Expected signal range (potentiometer): ≈0.5 V (upright) to ≈4.5 V (full recline) or similar linear range; values outside range indicate fault
Resistance check (if potentiometer): single-ended across sensor may read a few kΩ (vehicle-specific — consult service data)
If hall-effect: square/analog output or PWM; verify frequency/amplitude with scope per manufacturer specs
Open-circuit: infinite resistance on sensor circuit or no signal voltage; short to ground or battery: near 0 V or near supply voltage respectively

Diagnostic algorithm

Read and record codes and freeze frame with a capable scan tool; note any related occupant classification or airbag codes.
Disable the vehicle battery and follow manufacturer safety procedures for SRS/airbag work. Wait recommended time before accessing connectors.
Visually inspect the seat harness, especially through the seat cushion and at the hinge/sill area, for pinched, broken, or chafed wires.
Reconnect battery (or follow service procedure for live testing). Backprobe the sensor connector: verify reference voltage and ground with ignition ON. Compare to vehicle spec.
With scan tool showing live data or using a voltmeter/scope, move seat recline slowly and observe signal. Look for smooth linear change. If intermittent or no change, suspect sensor/harness.
Perform resistance/continuity checks with ignition OFF: measure sensor resistance (if applicable) and continuity to the seat module/ECU pins to isolate open/shorts. Wiggle harness to reproduce fault.
If supply/ground and wiring to ECU are good but signal is out of spec or erratic, replace the recline position sensor. If multiple sensors or modules report faults, consider the seat module or wiring harness replacement.
After repairs or replacements, clear codes, perform any required seat/occupant classification calibration per manufacturer, and confirm no return of B00C6 under test conditions.
If code returns with correct sensor and wiring, test/replace the seat control/occupant module and re-check communications and power supply to the module.

Likely causes

Damaged wiring bundle in seat hinge area (most common)
Connector pin corrosion or bent/missing terminal
Worn potentiometer inside sensor causing intermittent signal
Seat track/hinge mechanical issue preventing normal sensor travel
Failed seat ECU or intermittent power/ground to sensor

Fault status

⚠️ Status

Passenger seat recline position sensor circuit fault detected — signal missing, out of range, or intermittent. Can affect restraint/airbag occupant logic.
