Displaying and deleting Max and Min values:
The next functions we discuss give the user actual recorded values of system pressure. The UDS7-BX “remembers” the
maximum value of actual pressure that it reads. This is often referred to as “watchdog.” To access, follow these steps:
To know the maximum pressure the system has reached, press “M” to access the programming menu. Using the down arrow,
scroll down to “nAH”. Press “M” to select accessing the max value. The value displayed is the maximum actual pressure read
by the UDS7-BX. Press “M” again to exit the reading, and use the arrows to get to “MENU” and press “M” to exit the
programming menu.
The maximum pressures can be cleared from the UDS7-BX memory to enable monitoring of a NEW high in the system. To
clear the high pressure reading, access the menu, and scroll down to “CLr”. Press “M” to access the clear high function.
Scroll down to “YES” and press “M” to clear the high pressure reading.
Trouble shooting:
Use the “Err” menu option to perform an error check. When “Err” is displayed, press “M” to display any errors. The code
displayed reveals the error type.
