PTI Scrollback Display Items
The PTI scrollback display also contains a lot of informa-
tion. After entering the PTI display (“PT1 PASS” or “PT1
FAIL” appears), imagine that the data is stored in a table. The
first column identifies the number of the Full Pretrip test (PT1,
PT2, etc.) and the test result (PASS or FAIL). Each additional
column identifies information about an individual test result or
the time of the test.
The PTI scrollback display shows the following acronyms
and information:
DS Display Test Result
AM Amps Test Result
SN Sensors Test Result
HT Heat Test Result
DF Defrost Test Result
CL Cool Test Result
EX Extended Cool Test Result

test entries.

Press the SELECT key to scroll (to the right) to the next
individual test result stored with each Full Pretrip test (e.g.
