FUNCTION 28 STORED STATUS CODE COUNT
POINTER
( Push CONT 13)
This register contains the location of the last stored status
code recorded of the 16 stored status codes. These stored
status codes have caused a PMT controller shutdown
and/or disruption of normal vehicle operation.
To determine which stored status code was the last one
recorded, read the number stored in Function 28. Using the
Memory Map for your logic card, match the "stored status
code pointer number" [the number shown in (bold italics)
in the HS (Handset) number column] on the memory map,
with the number obtained from Function 28. This will be the
last stored status code recorded.
Note: When scrolling through the stored status code
register, the register always starts at status code 1 and
scrolls to status code 16. Instructions for scrolling the
register are in section 7.3.2 of this instruction booklet.
DASH DISPLAY INTERACTIVE MODES
The following functions (Functions 48 through 62) are
mode settings that are activated from the Interactive

these guidelines, an error code will be displayed to
prompt you to enter the correct setting:
If "80" is displayed, the setting is too low.
If "81" is displayed, the setting is too high.
