Trouble Code - Strange Results #6

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
Running the trouble codes command 03 for a know MAF failure returns only 5 
bytes of data after the 43 response when it should return 6.

For example, I unplugged the maf on a 2008 Mazda3.  The codes set are P0102 and 
P0113  When I run the 03 command the response is:
43 02 01 02 01 13 \r\r

It should be:
43 01 02 01 13 00 00

Or something like:
43 01 02 01 02 01 13

ANy idea why it would do this?

where did you get the protocol to interpret the response?
is there a manual or something?

This is a response from the ELM device and not a software bug, to my 
understanding.
