Tool warns for PGN 65259 while the engine is running with a distributed system

[naroner]

Per CARB regulations we only support the engine serial number from one ECU (SA 0), the tool flags SA 1 and 61 for not replying when the engine is running. (4.8.2) All 2013 and subsequent model year engines (except for heavy-duty engines certified to the Low Emission Vehicle III exhaust emission standards defined in title 13, CCR section 1961.2) shall have the engine serial number (ESN) available in a standardized format through the standardized data link connector. Only one electronic control unit per vehicle shall report the ESN to an SAE J1978/J1939 scan tool.

Perhaps we change this to Info instead of Warn?

[ericthomasswenson]

Support for component ID is expected from OBD Devices …

Possibly this was changed from Fail to warn years ago.

NACK with 03 conditions not correct … instead of 01 … implying not supported would be better behavior.

I think info can be sold with 03h to CARB

[ericthomasswenson]

Update document text to require only responses from function 0 devices, one of which must support ESN (SPN 588).

6.2.7 Component ID: Make, Model, Serial Number Support 6.2.7.1 Actions a. Destination Specific (DS) Component ID request (PG 59904) for PG 65259 (SPs 586, 587, and 588) to each OBD ECU.

6.2.7.2 Fail Criteria a. Fail if any function 0 device does not support PG 65259 with the engine running that supported PG 65259 with the engine off in part 1.
b. Fail if there is any difference between the part 2 response and the part 1 response, as PG 65259 data is defined to be static values.

6.2.7.3 Actions2 (NOTE: No warning message shall be provided for responses from non-OBD devices for PG 59904.)
a. Global Request for Component ID request (PG 59904) for PG 65259 (SPs 586, 587, and 588). b. Display each positive return in the log.

6.2.7.4 Fail Criteria2 for Function 0 a. Fail if there is no positive response from function 0. (Global request not supported or timed out.) b. Fail if the global response does not match the destination specific response from function 0 devices.

6.2.7.5 Warn Criteria2 for OBD ECUs Other than Function 0 a. Info if Component ID not supported for the global query in 6.2.7.3 with engine running.

[ericthomasswenson]

The current text may be harsh. A new proposal will be needed.

The ESN must be provided with the engine running.

[ericthomasswenson]

Perhaps,

6.2.7.2 Fail Criteria a. Fail if any OBD ECU NACKs (control byte = 1) its DS request, where the ECU supported PG 65259 in Part 1 b. Info if any OBD ECU NACKs (control byte = 2) its DS request. (2, access denied, conditions not correct - Engine running. c. Fail if there is any difference between the part 2 response and the part 1 response from an OBD ECU, as PG 65259 data is defined to be static values. d. Fail if no Function 0 device supports PG 65259 with the engine running.

[battjt]

How about? a. Fail if any OBD ECU does not respond or NACKs (control byte = 1) its DS request, where the ECU supported PG 65259 in Part 1

[ericthomasswenson]

See similar request from hybrid TF Mark Stepper item 4.

@ericthomasswenson

This has been partially fixed in 3.1.23, however instead of: "WARN: 6.2.7.5.a - Engine https://github.com/Equipment-and-Tool-Institute/j1939-84/pull/2 (1) did not support PGN 65259 with the engine running"

I am now getting: "FAIL: 6.2.7.2.c - Engine #2 (1) reported difference between the part2 response and the part 1 response"

It appears to me that it is not counting a NACK as the same response.
