Code B0080:04 Description

The seat position sensor is used to determine the proximity of the front driver or passenger seat position with respect to the front air bag. There are two states of seat position, forward and rearward. The seat position sensor interfaces with the Inflatable Restraint Sensing and Diagnostic Module (SDM) and allows the inflatable restraint sensing and diagnostic module to disable stage 2 of the air bag for a front seat that is forward of the forward/rearward point in seat track. The seat position sensor provides two current ranges, one range for the forward seat position and one for the rearward seat position. When the Inflatable Restraint Sensing and Diagnostic Module receives input from a seat position sensor that the seat is rearward, and the inflatable restraint sensing and diagnostic module will not disable stage 2 deployment. When the seat is forward, the Inflatable Restraint Sensing and Diagnostic Module will disable stage 2 deployment. The inflatable restraint sensing and diagnostic module monitors the seat position sensor circuit and if a fault is detected, the Inflatable Restraint Sensing and Diagnostic Module will set Diagnostic Trouble Code (DTC) B0080 and disable stage 2 frontal deployment. The DTC will be set when the Inflatable Restraint Sensing and Diagnostic Module detects the seat position sensor signal circuit is open for 2 s.

Precautions for SRS “AIR BAG” and “SEAT BELT PRE-TENSIONER” Service

Never probe the electrical connectors on air bag, side air curtain modules or seat belts.
Never disassemble or tamper with safety belt buckle/retractor pretensioners, adaptive load limiting retractors, safety belt inflators, or probe the electrical connectors.
Do not use electrical test equipment to check SRS circuits unless instructed to in this Service Manual.
Before servicing the SRS, turn ignition switch OFF, disconnect both battery cables and wait at least 3 minutes. For approximately 3 minutes after the cables are removed, it is still possible for the air bag and seat belt pre-tensioner to deploy. Therefore, do not work on any SRS connectors or wires until at least 3 minutes have passed.

Failure to follow this instruction may result in the accidental deployment of these modules, which increases the risk of serious personal injury or death.

Frequently Asked Questions about B0080:04 Code

What does the OBDII code B0080:04 mean?

The code B0080:04 indicates an open circuit in the passenger seat position sensor, which affects the airbag system's ability to determine the seat's position.

What are the common symptoms of code B0080:04?

Symptoms include an illuminated airbag warning light, possible deactivation of the passenger airbag, and error messages related to the airbag system.

What causes the passenger seat position sensor circuit to open?

Common causes include damaged wiring, disconnected connectors, a faulty seat position sensor, or corrosion in the electrical contacts.

Can I drive safely with code B0080:04?

Driving may be unsafe because the airbag system may not function correctly, potentially compromising passenger safety during a collision.

How do I diagnose the source of code B0080:04?

Visually inspect the sensor wiring and connectors for damage, use a multimeter to check for continuity, and scan for related codes that may help pinpoint the issue.

How do I fix code B0080:04?

Repairs may involve reconnecting or replacing damaged wiring, cleaning corroded connectors, or replacing the passenger seat position sensor if faulty.

Does the passenger seat position sensor affect airbag deployment?

Yes, the sensor helps determine airbag deployment force based on seat position, and a malfunction could lead to improper deployment or deactivation.

Can a weak battery cause code B0080:04?

While unlikely, a weak battery or inconsistent voltage can sometimes affect electrical circuits, including the seat position sensor.

How much does it cost to repair code B0080:04?

Repair costs vary but typically range from $100 to $500, depending on whether wiring repairs or sensor replacement is needed.

Can I reset code B0080:04 without repairing the issue?

Clearing the code without addressing the problem may temporarily turn off the warning light, but the issue will likely return and compromise airbag functionality.
