With the CanBus Multiplex Trainer, you can read the hexadecimal data used by your modules to communicate. You can also inject fake data to simulate a fault without compromising your vehicle's integ...

Security Access (0x27) is a fundamental mechanism within the UDS protocol that controls access to critical ECU functions such as reprogramming, coding, fault clearing, and the activation of special...

If we want to check the communication speed and the data displayed by the gauges on a real truck's instrument panel, we can easily do so using the Inpronic Dashboard in the simulation section. To d...

In automotive diagnostics over the CAN network, especially in Toyota/Scion vehicles such as the FR-S, reading Diagnostic Trouble Codes (DTCs) is not limited to a single request from the scanner, bu...

When a DTC OFF is performed on a light vehicle using any tool or tuner via OBD2, bench, or Open, this fault has three possible states: one where the check engine light does not illuminate when the ...

In advanced diagnostics of vehicles such as the BMW X5 E70, one of the most important aspects is the correct identification and interpretation of the Diagnostic Index (DI) within UDS communication ...

In advanced diagnostics of vehicles such as the BMW X5 E70, one of the most important aspects is the correct identification and interpretation of the Diagnostic Index (DI) within UDS communication ...

In vehicle diagnostics using the UDS protocol, when requesting fault codes through service 0x19 (for example, a request like 03 19 02 AF, which means “read DTCs by status mask”), the EC...

In vehicles such as the 2012 MINI Cooper, it has been observed that access to diagnostics is not enabled directly through UDS; instead, there is a prior mechanism at the CAN network level where the...

If you need to find a way to train yourself in the communication language your truck's modules use to interact, you can open the simulation dashboard of Inpronic's AI diagnostic suite. There, you c...

I am currently performing reverse engineering on a Mitsubishi vehicle, and while analyzing the module referred to as LIN, it is observed that when requesting fault code reading, the scanner sends a...

I am currently working on the emulation of a 2019 Cadillac ATS, and when I try to enter the DTC display function from the scanner, I receive the request 03 A9 81 1A 00 00 00 00. By analyzing the pr...

A mechanic who owns a workshop brought in a Maserati with steering wheel problems. The symptoms appeared to be related to the CanBus communication of the module. To verify this, he used the CanBus ...

The UDS (Unified Diagnostic Services) protocol is a diagnostic standard used in modern vehicles that enables communication between diagnostic tools and electronic control units (ECUs) through the C...

CAN (Controller Area Network) communication mainly operates in two modes: Broadcast and Request/Response, which differ in how data is transmitted within a vehicle. In Broadcast mode, modules send i...

The CAN bus communication network, using the OBD2 protocol, is standard in most vehicles from 2002 onwards. This means that the primary way to communicate the status of components such as sensors, ...

I’m working with CAN communication in an Audi vehicle and I have a question regarding the use of 29-bit identifiers (extended CAN), since I previously worked with 11-bit CAN where, when respo...

Did you know that when the MAF sensor fails in your vehicle, the ECM has an internally programmed emergency mode that maintains a constant reading in grams per second for the intake air value? This...

Great observation, Alex — you've spotted one of the more nuanced aspects of GM/GMLAN architecture. The +0x08 offset rule (request 0x7E0 → response 0x7E8) is part of the ISO 15765-2 / UD...

I am working on a reverse engineering project involving ECU emulation and CAN diagnostic communication on a GMC vehicle (GM/GMLAN architecture), and I have noticed something interesting regarding m...
