J1850 PWM/VPW ?
J1850 PWM/VPW ?
Hi, I recieved my uart model a adapter in the mail and when trying to get it to connect to my car I realized that the obd ii adapter doesn't support the GM or Ford protocols. Now I'm quite sad, as I didn't know about these various protocols before purchasing. Is there a reason why no support for this protocol is included? Could it possibly be a software addition? Thanks for the help
Re: J1850 PWM/VPW ?
J1850 is not supported and can't be added by software update.

Hi Stanley,
Can you tell us which other protocols (vehicle manufacturers) are not supported?
Thanks,
Bill

Re: J1850 PWM/VPW ?
Only the listed protocols on the product page are supported. All others are not supported.

Still problem with ford and Gm protocols....not work! PWR/VPW....
Re: J1850 PWM/VPW ?
Our OBD-II adapter does not suppot J1850.
Re: J1850 PWM/VPW ?
This is very unfortunate!
I have a 1998 Ford Mustang which supports only J1850 PWM on its OBDII port.
When i connect the OBD-II Telematics Advanced Kit (Arduino MEGA) - NOTHING. no output at all.
My understanding is that Ford used only J1850 not CAN in the early cars
Stanley: You say it only supports whats on the product page. That page says it supports OBDII and J1850 is a perfectly fine standard for OBDII. (https://en.wikipedia.org/wiki/On-board_ ... _protocols)
PLEASE to avoid other buyers to be frustrated PLEASE add a huge disclaimer that you DO NOT support the J1850 version of OBDII
NOTE:
Yes I'm a software guy. i downloaded the latest firmware from https://github.com/stanleyhuangyc/Ardui ... galoggerHD
Yes i even compiled and debugged it. At the moment you only seem to support (File: https://github.com/stanleyhuangyc/Ardui ... /OBD.h#L79)
typedef enum {
PROTO_AUTO = 0,
PROTO_ISO_9141_2 = 3,
PROTO_KWP2000_5KBPS = 4,
PROTO_KWP2000_FAST = 5,
PROTO_CAN_11B_500K = 6,
PROTO_CAN_29B_500K = 7,
PROTO_CAN_29B_250K = 8,
PROTO_CAN_11B_250K = 9,
} OBD_PROTOCOLS;
I looked up the ELM237 datasheet and added a constant for PROTO_J1850_PWM = 1 and set the protocol manually in config.h
Still no luck.
I love the idea of the product - but i'm giving up at that point;
Stanley - could you confirm this is a HARDWARE limitation? Are you using the ELM Chipset? Or is there hope for a determined hacker to make this work?? (I'm willing to invest another day into this if there is hope)
