FAULTY ELM 327 INTERFACES DE-MYSTIFIED (READ HERE)

[cxem]

At you the basic chip "STM32F032 - a drop"
You need the main chip "PIC"
====================================
Problem:

COMMAND: ATSPC
The operation has timed out.

0 - Automatic
1 - SAE J1850 PWM (41.6 kbaud)
2 - SAE J1850 VPW (10.4 kbaud)
3 - ISO 9141-2 (5 baud init, 10.4 kbaud)
4 - ISO 14230-4 KWP (5 baud init, 10.4 kbaud)
5 - ISO 14230-4 KWP (fast init, 10.4 kbaud)
6 - ISO 15765-4 CAN (11 bit ID, 500 kbaud)
7 - ISO 15765-4 CAN (29 bit ID, 500 kbaud)
8 - ISO 15765-4 CAN (11 bit ID, 250 kbaud)
9 - ISO 15765-4 CAN (29 bit ID, 250 kbaud)
A - SAE J1939 CAN (29 bit ID, 250* kbaud)
B - USER1 CAN (11* bit ID, 125* kbaud)
C - USER2 CAN (11* bit ID, 50* kbaud)

"STM32F032 - drop" - It is a small set of commands(program: OBD Car Doctor, Torque)

Ok, man. many thanks.... I will buy the interface with PIC chip

[samuraisuzuki]

Ok, I have it! It works and can read alot of data from Motor Control Unit.
But why cannot I write down the Injectors codes? Program says the Error and Interface is not compatible with the function.
(((
The victory seemed so close (((

Thank you so much!

The picture quality is not very good. But apparently you need to remove R2

Hi,

I seem to be having trouble connecting to CAN system ln my Fiat Bravo T-Jet 2009. Anyone can advise if my device is something wrong? Possible to modify?

Hi can a kind soul help please?

I scan interface in settings and multiecuscan find interface, when run test, first tests all ok, but the last 'COMMAND ATSPC: The Operation Has Timed Out'

but cannot connect to any module (engine, service, body, etc).

Many thanks!

Hi,
New to the forum but I'll jump straight in with a query...

I recently bought a cheapish "Pumpkin" branded wifi Elm327 box assuming that I'd probably have to modify it and remove the 120ohm resistor to get it to work correctly.
The error I get in MES is consistent with incorrect CAN termination. However, the PCB doesn't seem to have a 120ohm resistor. In fact, the resistance between can high/low pins appears to be 48.4k rather than the expected 120ohm.

Any thoughts?

Or do I just buy another. If so, any decent uk amazon sellers with quick delivery?
