If your OBD-II scanner displays B0060, your vehicle has detected that the passenger seat belt pretensioner deployment loop resistance is higher than the manufacturer’s specified range. Although your vehicle will typically continue to drive normally, this diagnostic trouble code (DTC) indicates that the Supplemental Restraint System (SRS) may not be able to deploy the passenger seat belt pretensioner correctly during a collision.

Seat belt pretensioners are designed to instantly remove slack from the seat belt before the airbags deploy, helping position the occupant for maximum protection. The Airbag Control Module (ACM) constantly monitors the electrical resistance of the pretensioner’s deployment circuit. If resistance becomes too high, the ACM stores B0060 and illuminates the Airbag Warning Light.

This guide explains what the B0060 code means, common symptoms, likely causes, repair costs, and how technicians diagnose and repair the problem.

What Does B0060 Mean?

The B0060 diagnostic trouble code indicates the Airbag Control Module has detected higher-than-normal resistance within the passenger seat belt pretensioner deployment loop.

Every seat belt pretensioner contains a pyrotechnic deployment circuit with a carefully calibrated resistance value. During every ignition cycle, the ACM performs a self-test by measuring the circuit resistance.

If the measured resistance exceeds the acceptable range, the ACM assumes the pretensioner may not deploy reliably during a collision.

Common causes include:

Open circuit
Broken wiring
Corroded connectors
Loose electrical terminals
Internal pretensioner failure

To prevent improper deployment, the ACM disables the passenger pretensioner and stores B0060.

Symptoms of B0060

Common symptoms include:

Airbag warning light illuminated
“Service Airbag” message
SRS warning light
Stored B0060 code
Passenger restraint system warning
Additional SRS-related trouble codes
No drivability issues

Because the pretensioner activates only during a collision, drivers usually notice no changes during normal driving.

Common Causes

1. Open Passenger Pretensioner Circuit

The most common cause is an open circuit caused by:

Broken wiring
Internal pretensioner failure
Loose connectors

2. Damaged Under-Seat Wiring

Repeated seat adjustment may eventually damage the harness through:

Broken conductors
Pulled wires
Pinched harnesses
Chafed insulation

3. Corroded Connectors

Moisture beneath the passenger seat may corrode electrical terminals and increase resistance.

Common causes include:

Wet carpeting
Water leaks
Beverage spills
Flood damage

4. Loose SRS Connector

A partially disconnected yellow SRS connector can easily create excessive circuit resistance.

5. Failed Passenger Pretensioner

Internal damage within the pretensioner firing circuit may increase resistance beyond acceptable limits.

6. Airbag Control Module Failure

Although uncommon, an internal ACM fault can falsely report excessive resistance.

How Serious Is B0060?

Extremely serious.

If resistance is too high, the passenger pretensioner may fail to deploy during a collision.

Potential consequences include:

Seat belt slack remains
Passenger movement increases
Reduced airbag effectiveness
Increased injury risk

Repairs should be performed as soon as possible.

Can You Drive With B0060?

Mechanically, yes.

From a safety standpoint, no.

Although the vehicle remains drivable, the Supplemental Restraint System may not fully protect the passenger during an accident.

How to Diagnose B0060

Step 1: Scan the SRS Module

Use a professional scan tool capable of accessing:

Supplemental Restraint System
Airbag Control Module
Body Control Module

Most inexpensive OBD-II readers cannot retrieve B-codes.

Step 2: Inspect Passenger Seat Wiring

Inspect beneath the passenger seat for:

Broken wiring
Loose connectors
Pinched harnesses
Corrosion

Move the seat through its complete adjustment range during inspection.

Step 3: Inspect SRS Connectors

Inspect the yellow connectors for:

Bent terminals
Corrosion
Loose pins
Broken locking clips
Physical damage

Step 4: Measure Circuit Resistance

Following manufacturer procedures, verify deployment loop resistance using approved SRS diagnostic equipment.

Never use a powered test light or jumper wire on an SRS circuit.

Step 5: Inspect the Pretensioner

Inspect for:

Previous deployment
Internal damage
Retractor malfunction
Water intrusion

Replace the pretensioner assembly if testing confirms internal failure.

Common Repair Solutions

Repair	Estimated Cost
Repair damaged wiring	$150–350
Replace SRS connector	$100–250
Replace passenger pretensioner	$350–900
Replace seat wiring harness	$300–700
Replace Airbag Control Module	$900–2,000

Common Diagnostic Mistakes

Many technicians replace the pretensioner before inspecting the electrical circuit.

However, B0060 is frequently caused by:

Corroded connectors
Broken harness wiring
Loose electrical terminals
Increased circuit resistance from poor connections

Always inspect and test the wiring before replacing expensive SRS components.

Vehicles That Commonly Experience B0060

How to Prevent B0060

Although some failures cannot be prevented, these practices help reduce the risk:

Protect under-seat wiring
Avoid pinching the seat harness
Keep carpets dry
Disconnect the battery before removing seats
Replace damaged connectors promptly
Repair SRS warning lights immediately

Frequently Asked Questions

What causes B0060?

The most common causes include broken wiring, corroded connectors, loose SRS connectors, an open pretensioner circuit, a failed passenger pretensioner, or Airbag Control Module failure.

What does “Resistance High” mean?

It means the ACM detected more electrical resistance than expected in the passenger pretensioner’s deployment loop, usually indicating an open circuit or poor electrical connection.

Is B0060 dangerous?

Yes.

The passenger seat belt pretensioner may fail to deploy during a collision, reducing the effectiveness of the restraint system.

Can I clear B0060 myself?

Yes, but unless the electrical fault has been repaired, the code will return after the next SRS self-test.

Does B0060 always require replacing the pretensioner?

No.

Many repairs involve correcting damaged wiring, cleaning connectors, or repairing poor electrical connections.

Will B0060 affect vehicle performance?

No.

The code affects only the Supplemental Restraint System and has no impact on engine, transmission, steering, or braking performance.

Final Thoughts

The B0060 code indicates that the passenger seat belt pretensioner deployment loop resistance is higher than factory specifications, suggesting an open circuit or excessive resistance that could prevent proper pretensioner deployment during a collision. While your vehicle may continue to operate normally, the passenger restraint system may not provide the level of protection it was designed to deliver.

Fortunately, many B0060 repairs involve correcting damaged wiring, repairing loose connectors, or cleaning corroded terminals rather than replacing the pretensioner itself. A thorough diagnosis using manufacturer-approved procedures is the best way to restore full SRS functionality.
