I did the "FEATURE 12 1" SMS command, but got no response. Are those
commands documented somewhere, or is it a "read the code" deal? (It is cool
to be able to read the code.)
I get the same "not charging" status with the charge port door open.
When I do a GPS command, I get back a link to 52.042460,-3.944089 which I
assume is the default position in Wales.
So, it seems the OVMS module isn't getting any of these CAN messages. Is
there a way to tell if the board is getting any messages at all?
With Cathy's help, I checked continuity and all four pins going to the MCU
board. They all check out, as do the four twin wires to the other connector.
When plugged in, after the start up sequence, I get a solid green LED on
each board and a blinking blue LED on the modem board.
Finally, I'm sure my diag port is functional as it has been working with my
Tattler (although the Tattler is going through some brain surgery right now
so I can't confirm that it's working today).
BTW, I notice the generated GPS link takes you to a static map that can't be
scaled or panned. This makes it impossible to tell where the pin is if you
don't recognize any features in the static map.
I like using a simpler link that gets you a fully functional map:
http://maps.google.com/maps?q=52.042460,-3.944089Also, I'm also not a big fan of the Tesla logo for the pin, but I have an
unusual history with the company that may be coloring my attitude on that.

Tom,
Good to have you aboard.
We haven't been able to test the module on 1.5 cars (which is why we're only
shipping to end-users with 2.x cars). The problem we've had is that all the
developers involved have 2.x cars.
That said, the module _should_ work in a 1.5 car. Scott451 did the original
bus decodes on a 1.5 car, and while there are some differences, he did
document the messages (but we haven't been able to verify this as we have with
the 2.x cars).
First, some trivia:
Our current master document on CAN bus messages is at:
https://github.com/markwj/Open-Vehicle-Monitoring-System/blob/master/vehicle/C
ar%20Module/canbus_notes.txt
and that includes all of Scott451's published work, plus our own additions.
The SOC message is on the CAN bus - message ID#100, B1=0x80. There is
supposedly no difference between the 1.5 and 2.x models for this message.
To get the charging messages correctly, you will need to set the CARBITS
feature to a 2008 model roadster. An SMS command:
FEATURE 15 1
should enable bit#1 of the carbits, and permanently record this as a 2008
roadster.
The "Not charging" just means the charge port door is closed (or bit#2 of B2
on id#100 B1=0x96 is zero). The SOC and Ideal range being zero is similar zero
(default) values.
So, either none of these messages are getting from the CAN bus to the module,
or the messages are completely different on a 1.5 car. I suspect the former.
Can you try:
a) A "GPS" SMS command - do you get a location in Wales (default), or the true
location?
b) Open the charge port door, and repeat the "STAT" command - do you get a
charging reply?
and let us know the result?
The problem could also just be a faulty module (we had some factory soldering
issues with early modules), so please verify the soldering looks good, and
trace continuity test, particularly on the CAN bus side? Or, a loose
connection on the CAN bus cables (two pins CAN-L and CAN-H), so can you check
that with a continuity tester? If you have the opportunity, you could try it
in a 2.x roadster.
There is a wiring schematic at:
https://github.com/markwj/Open-Vehicle-Monitoring-System/raw/master/vehicle/Ca
r%20Module/OVMS_V5a.png
My guess for this problem is a loose/broken cable on the CAN bus side -
somewhere between the DIAG connector and the telco-style jacks connecting to
the PIC motherboard.
It would be really helpful if you could help us test this and iron out any
wrinkles for the 1.5 cars. We've had some enquiries from 1.5 end-users, but
have told them to hold-off for the moment until we can verify things work in a
1.5 car.
Regards, Mark.

I just got the OVMS board plugged into our v1.5 Roadster. I haven't jumped
through the hoops to get a data plan on my SIM card yet, so I'm just using
SMS.
I registered my phone and changed my password. Those commands worked as
expected. I then did a STAT and got back:
Not charging
Ideal Range: 0 Km
SOC 0%
It's true that it's not charging, but the car is actually at 96% and 185
ideal miles.
What should I do next?
