I'm trying to learn about the PCM. I have the Helm manuals. When starting with the OFF + WARMER buttons, it reads out no history on the different catagories,

and then up comes S036, S044, S060, S061. I see where the prefix P and the numbers (codes) are listed, but where am I missing the S's?

OK,I didn't explain it correctly. There are no catagory codes. IPC,SIR etc. Then the S + numbers + history appears. I still am tring to find what the S means. Is it a snake getting ready to bite me?

The SO codes are listed under the suspension ride control section.

You should have 2 service manuals. One is for powertrain....the other is body systems.
