B00B6: Driver Seat Recline Position Restraints Sensor (Subfault)

What it means

Fault on the driver seat recline position sensor — detects backrest angle, used by the airbag controller for deployment scaling.

At a glance

• Usually lights the airbag (SRS) or body-system warning light

How it works

The driver seat recline position restraints sensor reports the angle of the seatback for use by the restraint controller. B00B6 indicates a fault associated with that recline-position sensor or its circuit, not the seat track position sensor; it does not specify the failure mode.

Common causes

Most likely first.

1. Faulty driver seat recline position sensor
2. Damaged wiring or connector at the seatback
3. Loose or corroded electrical connection
4. Fault in the restraint control module

Symptoms

• Warning light or symbol related to the affected system
• Comfort or safety function impaired

How to diagnose it

1. Read restraint-module codes and available driver-seat recline data with a compatible scan tool.
2. Adjust the driver seatback through its normal range and observe whether the reported recline position changes consistently or the fault returns at a particular angle.
3. Inspect the seatback sensor area and wiring for damage, pinching, or strain as the seat reclines.
4. Following the manufacturer's restraint-system precautions, inspect the recline sensor connector for looseness, corrosion, or damaged terminals.
5. Test the recline sensor and its circuit using the manufacturer's diagnostic procedure and specifications.
6. If the sensor and wiring check out, test the restraint control module and its connections.

Common fixes

• Reposition wiring that is pinched or strained by seatback movement.
• Reconnect and secure a loose recline sensor connector.
• Repair damaged wiring or terminals in the recline-position circuit.
• Replace the driver seat recline position sensor if testing confirms it is faulty.
• Repair or replace the restraint control module if manufacturer-specific diagnostics confirm an internal fault.

Can I keep driving?

The restraint controller may not receive the driver seatback angle it needs for airbag management. Arrange prompt diagnosis and assume airbag performance may be affected until the fault is repaired.
