Introduction
This manual provides the necessary information for the proper use of Tri
Mark
’s
e-
ASK
System
including module and keypad in the Prevost system.
Push to Start
This vehicle is equipped with an advanced push to start ignition system. The start/ignition
sequence is accomplished via CAN messaging between the Prevost Mux Module and the e-
ASK
module. When the push button start switch is pressed, the following sequence occurs:
•
Foot must press the Brake Pedal, Vehicle must be in “Neutral”, and the “Parking Brake”
must be set
•
Press the “Start Button”
•
The Prevost Mux module sends the e-
ASK
module a “Start request” command
•
The e-
ASK
module pings LF antenna 2 (searches for fobs in proximity)
•
A fob in the proximity of antenna 2 receives the ping and the LED on the face of the fob
blinks once
•
If an authorized fob is found, the e-
ASK
module sends an “authorized fob found”
message to the Prevost Mux module.
•
The Prevost Mux Module performs the remainder of the start sequence
•
If an authorized fob was not found, the e-
ASK
module sends “No authorized fob
detected” to the Prevost Mux module
Override/Failsafe: When an authorized fob is not detected, a popup will appear in the dash
‘'KEYFOB NOT FOUND". There is a 1-minute time period before the Mux module cancels the
start request. If a valid code is entered on the keypad during this time, the keypad informs the
Mux module via CAN messages that an authorized user is present. The user has 30 seconds
to press the start switch a second time to enable engine start.
