1999 Jeep Grand Cherokee JTEC+ Fault Class types

[Chasetheride]

I just started working on my 1999 Grand Cherokee and would like to know if anyone knows the Fault Class types in VCM Editor. The options are Disabled and Type 1-15. It does not have SES and MIL options like most I am finding information on.

I think they mean the detection strategy. Meaning if the code sets as soon as it is detected or 2 trip fault, X amount of code cycles, X amount of complete run cycles, certain temperature, rpm, open/closed loop... something along those lines.

i am wondering the same thing as well, it would be nice if they were documented, but a strategy of leaving the original value alone or disabling it should work in most cases. i would presume the people disassembling these ECMs found values like 0x00 to 0x0A (0x00 probably disabled) and never really found the time to care what 0x01-0x0A mean.
