Default Requesting ON-BOARD DIAGNOSTICS BOSCH M5.2.1 ENGINE MANAGEMENT Manual

I am trying to research some error codes that popped up on my truck. have the attached copy of the Bosch Motronic manual. Unfortunately, I am not sure where I downloaded it.

My version has some jumbled text, example: please see the screen shot below. Does anyone have a better version of this manual to share? Thanks in advance!

I think that is the original text and it is not jumbled. The seemingly random words are actually parameter/variable names, and their meanings are explained on page 15.
