The HTT is a 'poor' tool . . quote from a senior MB tech . .
This table shows that it's not an "infallible" tool for diagnosing EA problems just as a normal scanner (AST Retreiver, etc) isn't. It give ambiguous codes as the table below shows.
The sub-codes are shown (and read if at fault) in subsequent DTCs in most scanners.
So if you think the "HHT" will point to the 'culprit', you'll be dissapointed!
