Bootloader

 

 

The AX141100 can be upgraded with new application firmware using the 

Bootloader Information

 

section. This section details the simple step-by-step instructions to upload new firmware provided by 
Axiomatic onto the unit via CAN, without requiring it to be disconnected from the J1939 network.  
 

Note: To upgrade the firmware use Electronic Assistant ® 

 V5.13.84.0 or higher. Further, the 

AX141100 device needs to be in Interface Mode (CAN receive filtering enabled) in order to be 
accessible by EA. 
 
Note: In case it is preferred not to set the device to Interface Mode, see Step 3.1 below. 

 
 
1.  When EA first connects to the ECU, the 

Bootloader Information 

section will display the following 

information.
