ISO 15765 defines how diagnostic protocols like UDS and KWP2000 are implemented over CAN. It specifies the message formats, timing parameters, and error handling procedures for diagnostic communication.

3.6 Protocol Selection

The protocol used depends on the vehicle’s architecture and the specific ECU being diagnosed. DTS Monaco typically auto-detects the correct protocol or allows the user to manually select it.

4. What Diagnostic Services Within DTS Monaco Are Used?

Within DTS Monaco, specific diagnostic services are utilized to access ECU error counters, providing detailed insights into ECU health and communication status.

4.1 Read Data By Identifier (0x22)

This service is commonly used to read specific data identifiers (DIDs) that contain error counter values. The request specifies the DID of the error counter, and the ECU responds with the current value.

4.2 Read DTC Information (0x19)

While primarily used for reading Diagnostic Trouble Codes (DTCs), this service can also provide information about the number of times a specific DTC has occurred, which can be related to error counters.

4.3 Routine Control (0x31)

Some ECUs use routine control services to reset or manipulate error counters. This service allows DTS Monaco to execute specific routines within the ECU, such as clearing error counters after a repair.

4.4 Input Output Control By Identifier (0x2F)

This service allows for controlling the input and output signals of the ECU. Although not directly related to reading error counters, it can be useful in diagnosing issues that may be causing the errors.

4.5 Communication Control (0x28)

This service is used to enable or disable communication on specific communication channels. It can be helpful in isolating communication issues that may be contributing to error counts.

4.6 Example Scenario

For example, to read the communication error counter for CAN channel 1, DTS Monaco would use the “Read Data By Identifier” service (0x22) and specify the DID associated with that counter. The ECU would then respond with the current value of the counter.

5. How Can Reading ECU Error Counters Help in Diagnostics?

Reading ECU error counters can significantly aid in diagnostics by providing insights into the frequency and nature of communication and system errors.
