EZ-Cal Messages
“Help Messages” will appear on the EZ-Cal scan tool as a means of explaining operating and non-
operating function(s) and system errors or interruptions that are accompanied by flash codes. It can
also be used for verifying system operation. Refer to the EZ-Cal Instruction page for additional help
with EZ-Cal operation.
To access messages, power the system up, (it is not necessary to have the engine running) the
EZ-Cal display will illuminate and read “HELP - PRESS ENTER”. Press ENTER to view current
message. Press ENTER a second time then use RIGHT and LEFT arrow buttons to access up to 30
