How do DTC codes work?ĭiagnostic Trouble Codes or OBD-II (in light-duty vehicles) or J1939 (in heavy-duty vehicles) trouble codes are codes that the vehicle’s OBD system uses to notify you about a problem. That code is known as a (DTC) diagnostic trouble code. Any time the system detects a problem, it records that problem as a code. The vehicle’s electronic system performs self-diagnosis and reporting. If a vehicle’s manufacture date is 1996 or newer, it will most likely be OBD-II compliant. SAE is now called SAE International, and it is the professional organization that develops standards for automotive engineers. These codes were created by the Society of Automotive Engineers (SAE) to help vehicles comply with emission regulations. The system can be set up to deliver the alert right to the maintenance department. In vehicles equipped with a telematics system, the alert can be delivered directly to the fleet. When the vehicle’s OBD system detects a problem, it generates a specific DTC code and transmits the alert to the vehicle’s instrument panel as a warning light. Different DTC codes represent specific problems in your vehicle. Let’s start by explaining the DTC meaning first.Ī DTC code is a series of diagnostic trouble codes used by a vehicle’s onboard diagnostics (OBD) system to alert you when a vehicle experiences a malfunction.

Understanding DTC codes and how they integrate with your fleet software solution can help improve driver safety and deliver healthy ROI. Having the right vehicle diagnostics software system in place to deliver fault codes in real-time may help keep your fleet running more efficiently and smoothly.

If you have a fleet management software system in place, the DTC codes will be sent in real-time to a fleet manager or technician. These trouble codes are often referred to as DTC codes.ĭiagnostic Trouble Codes or DTC codes help you understand what needs to be fixed so you can keep your vehicle operational and safe. You should not attempt to apply any software updates without fully understanding the information contained in the Technical Service Bulletin.When a vehicle’s on-board diagnostics system detects a malfunction, it generates the appropriate diagnostic trouble code and usually alerts the driver via a warning light or other indicator on the vehicle’s instrument panel.

In many cases, software updates are only part of the full repair process.

Technical Service BulletinsĪny software update will have an associated Technical Service Bulletin describing the problem or application to be fixed. For vehicles originally sold in other markets contact the local Toyota representative. This service is only available for vehicles officially marketed and sold by Toyota Motor Europe NVSA. Add the relevant Bulletin ID and the system will present software updates relevant to the VIN, model & Model code. To make this process more simple, the download function requires the vehicle identification number (VIN) to be entered first. There are often additional vehicle parameters that need to be considered before selecting the correct update.
