Causes

Damaged, corroded, or disconnected sensor connector or wiring harness on the right side retention sensor 3
Failed retention/buckle or seat occupancy sensor module
High resistance or short circuit in the sensor wiring (to ground or supply)
Poor grounding, water ingress or corrosion at connector
Faulty restraint control module or internal module memory error
Recent seat removal, repair or servicing that disturbed connector/harness

Symptoms

SRS / airbag warning light illuminated on instrument cluster
Seat belt warning or occupant classification message (may vary by model)
Possible disabling of associated restraint deployment (fault stored)
Diagnostic trouble code stored in SRS module (B0098)
Intermittent faults when seat moved or vehicle driven over bumps

What to check

Read and record all stored SRS codes and freeze frame data with a compatible scan tool
Visually inspect the right side retention sensor connector and wiring for damage, corrosion, bent pins or water contamination
Wiggle test: move the seat and wiring while observing live data / DTC status to look for intermittent changes
Check connector mating and retention clips; ensure connectors are fully seated
Measure continuity and resistance of sensor circuit (compare both pins and to chassis ground) and compare against factory specifications if available
Check supply and ground presence at the sensor connector with key on (observe safety procedures for SRS systems)

Signal parameters

Type: discrete switch/sensor circuit (typically reports latched/unlatched or presence/absence)
Expected behavior: a defined open or closed state corresponding to buckle/retention status; should be stable and not fluctuating
Electrical: sensor circuit will show continuity in one state and open in the other; reference supply or pull-up may be present (verify against wiring diagram)
Fault indications: open circuit, short to ground/supply, high resistance, or intermittent signal transitions

Diagnostic algorithm

Use an OEM-capable SRS scan tool to read all SRS codes and module live data. Note any related codes and freeze frame.
Disconnect vehicle battery per manufacturer SRS safety procedures before accessing seat connectors (follow service manual).
Perform visual inspection of the right side retention sensor, connector, and wiring (check under seat, along harness, and at seat rail pivot points).
Reconnect battery (as required by procedure) and with the ignition on, measure supply voltage and signal state at the sensor connector pins using the wiring diagram to identify pins. Observe behavior when buckling/unbuckling or moving the seat.
If open or high resistance suspected, remove the sensor and measure continuity/resistance directly across sensor terminals to verify operation. Compare to known-good sensor if available or to manufacturer specs.
If wiring fault suspected, perform pin-to-module continuity checks to locate opens/shorts. Repair any damaged wiring, terminals or corroded connectors and apply corrosion protection.
After repairs, clear codes and cycle ignition; verify code does not return and monitor live data while moving seat to confirm stable signal.
If fault persists after wiring and sensor verified good, consider replacing the right side retention sensor assembly or consult manufacturer guidance to evaluate SRS control module operation.

Likely causes

Loose, corroded or disconnected connector at the right side retention sensor
Broken or pinched wiring in the seat harness (common at seat rail pivot)
Failed retention sensor (internal switch or electronics)
Ground or supply fault to the sensor circuit
