Connect to the Vehicle to Start the Proterra Diagnostics Tool
This process will guide the user to connect to the vehicle with the Proterra Diagnostics Tool.
1. Turn ON the 12/24V rear Vehicle Master Disconnect located behind the vehicle curbside rear
charge port access panel.
2. Turn ON the bus Master Run Switch at the Driver's Workplace and ensure the Dash screen is
ON to display “KEY ON”.
a. This places the vehicle into Key On / Low Voltage state for controller versions to be
checked prior to software flash.
3. For Body Controller Programming:
a. Turn OFF the Master Run Switch at the Driver’s Workplace and ensure the dash screen
is OFF.
b. Turn ON the bus “programming switch” inside the street side wheel well box.
4. Using a T30 Torx screwdriver or appropriate tools, remove the two access covers:
a. Street side wheel well electronics cabinet (ECAB) panel for access to the OBDII Port.
b. Rear deck access panel for OBDII Diagnostic port (NOTE: on E2-35 foot buses this is
located behind the rear barn doors on the left hand side).
5. Power up (boot) the Proterra-supplied laptop containing the Proterra Diagnostic Tool.
