In the automotive industry, a Technical Service Bulletin (TSB) is a communication issued by a vehicle manufacturer to authorized dealerships and service centers. It provides technical information and instructions on how to address specific issues, improvements, or updates related to their vehicles. TSBs aim to assist technicians in diagnosing and repairing problems effectively and efficiently.

TSBs are typically issued in response to common or recurring problems that may not be safety-related but could impact the vehicle's performance, reliability, or customer satisfaction. They cover a wide range of topics, such as:

Troubleshooting guides: TSBs may include detailed steps for diagnosing and identifying specific issues based on reported symptoms.

Repair procedures: The bulletins provide guidance on how to fix the identified problems, including recommended tools, parts, and methods.

Software updates: Some TSBs may involve updates to the vehicle's software or firmware to improve its performance, fuel efficiency, or other functions.

Product recalls: While TSBs are not recalls, they can sometimes address problems that could lead to a recall if not appropriately resolved.

Service tips: TSBs may provide tips and best practices for vehicle maintenance and service.

TSBs are distributed internally within the manufacturer's network of dealerships and service centers. They are not typically sent directly to vehicle owners, and manufacturers are not obligated to notify owners of TSBs. However, if a vehicle owner experiences a specific issue, the dealership or service center can refer to the relevant TSB to address the problem appropriately.

It's worth noting that while TSBs are essential resources for authorized technicians, they are not legally binding like recalls. Recalls are issued when a safety-related defect is identified, and manufacturers are required to notify affected owners and offer free repairs or replacements for the affected parts or systems. On the other hand, TSBs focus on technical guidance and recommended procedures to address non-safety-related issues.
