Debug vs Normal messages in Tesla Roadster

I'm not having much luck trying to differentiate between debug and normal alert messages in the Tesla Roadster. So, here is my working so far, and calling out for ideas. First, here is what is known about the CAN bus message relating to this: Error Notification ID=0x100 B1=0x93 B2=On, Off, Severity, etc, indication B3=Error code LSB B4=Error code MSB (error code 0xFFFF means no error) B5=Data LSB B6=Data B7=Data B8=Data MSB N.B. Regarding B2, we've seen: 0x01 = 00000001b = Show Alert 0x00 = 00000000b = Cancel Alert 0x05 = 00000101b = Show Alert 0x04 = 00000100b = Cancel Alert 0x15 = 00010101b = Show Message 0x14 = 00010100b = End Message Suggestion is that bit0 is set when alert is raised, and zeroed when alert is cleared. Here is some raw can bus messages showing some alerts coming and going: 6.6947 100 93 00 FF FF 00 00 00 00 ->VDS (message to VDS 93) 13.4250 100 93 05 78 03 00 01 00 00 ->VDS (message to VDS 93) 20.1151 100 93 05 78 03 00 01 00 00 ->VDS (message to VDS 93) 26.8368 100 93 05 78 03 00 01 00 00 ->VDS (message to VDS 93) 33.5484 100 93 05 78 03 00 01 00 00 ->VDS (message to VDS 93) 40.2862 100 93 05 78 03 00 01 00 00 ->VDS (message to VDS 93) 46.9766 100 93 05 78 03 00 01 00 00 ->VDS (message to VDS 93) 53.6772 100 93 05 78 03 00 01 00 00 ->VDS (message to VDS 93) 60.3577 100 93 05 78 03 00 01 00 00 ->VDS (message to VDS 93) 63.2089 100 93 04 78 03 00 00 00 00 ->VDS (message to VDS 93) 67.0663 100 93 00 FF FF 00 00 00 00 ->VDS (message to VDS 93) 73.7502 100 93 00 FF FF 00 00 00 00 ->VDS (message to VDS 93) 80.2421 100 93 05 8D 04 20 00 00 00 ->VDS (message to VDS 93) 80.4511 100 93 05 8D 04 20 00 00 00 ->VDS (message to VDS 93) 87.1387 100 93 05 8D 04 20 00 00 00 ->VDS (message to VDS 93) 93.8198 100 93 05 8D 04 20 00 00 00 ->VDS (message to VDS 93) 100.5295 100 93 05 8D 04 20 00 00 00 ->VDS (message to VDS 93) 107.2297 100 93 05 8D 04 20 00 00 00 ->VDS (message to VDS 93) 113.9373 100 93 05 8D 04 20 00 00 00 ->VDS (message to VDS 93) 120.6307 100 93 05 8D 04 20 00 00 00 ->VDS (message to VDS 93) 121.7428 100 93 04 8D 04 20 00 00 00 ->VDS (message to VDS 93) 127.3396 100 93 00 FF FF 00 00 00 00 ->VDS (message to VDS 93) 128.3633 100 93 05 91 04 00 02 00 00 ->VDS (message to VDS 93) 134.0215 100 93 05 91 04 00 02 00 00 ->VDS (message to VDS 93) 140.7018 100 93 05 91 04 00 02 00 00 ->VDS (message to VDS 93) 147.4018 100 93 05 91 04 00 02 00 00 ->VDS (message to VDS 93) 147.9951 100 93 04 91 04 00 02 00 00 ->VDS (message to VDS 93) 154.1413 100 93 00 FF FF 00 00 00 00 ->VDS (message to VDS 93) 160.8654 100 93 00 FF FF 00 00 00 00 ->VDS (message to VDS 93) 167.5743 100 93 00 FF FF 00 00 00 00 ->VDS (message to VDS 93) 174.5784 100 93 00 FF FF 00 00 00 00 ->VDS (message to VDS 93) 181.3024 100 93 00 FF FF 00 00 00 00 ->VDS (message to VDS 93) 188.0697 100 93 00 FF FF 00 00 00 00 ->VDS (message to VDS 93) 194.7832 100 93 00 FF FF 00 00 00 00 ->VDS (message to VDS 93) 201.4736 100 93 00 FF FF 00 00 00 00 ->VDS (message to VDS 93) The message shown on the car's VDS includes 4 bytes of data, so we are assuming that is B5..B8. The most likely seemed to be B2, which we don't normally report back to the server. So, I switched my car to report that rather that the Data (B5..B8) and here is what I got: rx msg P ETR2N,1165,5 rx msg P ETR2N,888,5 rx msg P ETR2N,1124,5 rx msg P ETR2N,1166,5 rx msg P ETR2N,1146,5 rx msg P ETR2N,954,1 rx msg P ETR2N,1146,5 rx msg P ETR2N,1146,5 rx msg P ETR2N,1146,5 rx msg P ETR2N,1146,5 1146 (DMC Motor Fan Problem) is a debug message. 954 (line voltage lost sync), 1166 (release parking brake), 888 (disarm vehicle with keyfob), 1165 (door ajar) and 1124 (unsafe gear shift) are not. The last number (5 or 1) is the B2 value corresponding to the alert. I have no idea why 954 should be B2=1 and the others B2=5, but it seems to have no relation to the debug level of the alert. So, how about the ID number of the alert itself? Well, here is the list of known alerts, with the ID number shown in binary, hexadecimal and decimal, followed by the message: 0000000000011001 0019 25 Memory Stick transfer in progress (%d%%) 0000000000110101 0035 53 GPS: No data fault 0000000100001101 010d 269 BSM: Negative contactor/economizer stuck low 0000000100011011 011b 283 BSM: Isolation fault 0000000100011110 011e 286 BSM: Isolation fault while contactors closed 0000000100011111 011f 287 Power train Problem Service Required 0000000110011001 0199 409 TPMS: Hardware Error 0000000110101100 01ac 428 12V Battery Service Required 0000001001011100 025c 604 Battery Low Power Reduced 0000001001011110 025e 606 ESS: Range Mode Remaining charge uncertain 0000001001100011 0263 611 ESS: Almost empty - Car stops in 1 mile 0000001101110010 0372 882 Before starting, charge port door must be closed 0000001101111000 0378 888 Disarm vehicle with key fob before starting 0000001110100110 03a6 934 DMC FW: Line OverCurrent Peak Fault 0000001110101000 03a8 936 Charging Problem 0000001110101001 03a9 937 Charge Problem Extension Cord Detected 0000001110110001 03b1 945 System too hot - Vehicle shutting down 0000001110111001 03b9 953 Line Voltage Lost Sync 0000001110111010 03ba 954 Line Voltage Lost Sync 0000001111001110 03ce 974 DMC FW: Pole Current Error Fault 0000001111010101 03d5 981 DMC FW: Bad State Transition Fault 0000001111000000 03c0 960 DMC FW: VBrickMax versus VBattery Error fault 0000010000110001 0431 1073 DMC FW: PhaseA OverTemp warning.

I don't see any pattern. It has also been reported that one single ID can have both debug and non-debug variants to the message - see: http://www.teslamotorsclub.com/showwiki.php?title=Roadster So, here is all the error codes and data that we've seen for the past few months (error code, followed by data bytes in binary, hex and decimal): 0 00000000000000000000000000000000 00000000 0 3 00000000000000000000000000000000

Re: [Ovmsdev] Debug vs Normal messages in Tesla Roadster

> 1426 00000100000000000000000000000000 04000000 67108864 That one is probably from my car, the error number and data value agree. Photo available upon request. Hopefully, it's not a common error. I'm running the VDS in debug mode, which changes the text message, but with that, my alert said: HVAC: High current pump failure This error shuts down the coolant pump and aborts any charge in progress and won't allow a charge to start. It's not a good message to see. Tesla diagnosed it as the coolant pump "running too hard" (which I take to mean drawing too much current), which they attributed to the coolant level being too low. Upon their advice, I added 1/2 cup of distilled water and it's been fine since. Tom

Can-re tool

Hi I don't know whether this is the right list for this. I can't get the can-re tool to run on Windows. I downloaded EV.pm and common::sense, but it yields this: common/sense.pm did not return a true value at ../plugins/EV.pm line 121, <DATA> line 451. BEGIN failed--compilation aborted at ../plugins/EV.pm line 121, <DATA> line 451. Compilation failed in require at canretool.pl line 38, <DATA> line 451. BEGIN failed--compilation aborted at canretool.pl line 38, <DATA> line 451. !help Thanks Sharanga Nirvtek

US Volt sampling

Hi folks, Has anyone done any data logging on US Volts? I've got a couple of US contacts with Volts and wonder if it could help us figure out ONSTAR-like functionality in Europe. Nikki. Sent from my iPhone

OVMS Leaf Support
by Jeremy Whaling 02 Nov '13

02 Nov '13

Hi All! Just joined the list, I'm interested in helping sniff the car CAN bus of the leaf to help with development. One of my main goals is to have the ability to start and stop charging remotely via SMS. I also would like to have better control over remote climate control activation (heat/AC/vent/defrost etc), so I am really interested in sniffing the traffic when doing a charge timer override and invoking the remote climate control over carwings. I also have a Brusa charger under the hood but it's located on the ev bus (and I believe not query-able from the car can bus) so I'm not sure how much it can help. Anyways, I'm currently on a business trip but I'm ordering a PCAN (can-usb) tool today and hope to be monitoring soon! Take care, Jeremy Whaling
