Freightliner Truck Dash Reads NO A65

Posted on January 15, 2012 08:56 AM, in ASE Truck and Diesel Mechanics

When starting the truck or the truck is idling, the display will show NO A65. This is really reading no abs. Freigthliner uses the number 6 for the letter b and the number 5 for the letter s in the display.

This displays for 2 reason.
1. During ignition the abs module did not have time to report in to the instrument cluster.
"You will not get an abs fault light in this condition"
There is not a problem. The message will go away. The ABS module has not reported to the Instrument Cluster yet.

2. This will display when the abs module has lost power and/or ground or even a bad abs module.
"You will get and abs fault light in this condition"
There is a problem further diagnostics is required.
