need help with abs 136

136 is just the electronic address for the ABS module. It is not a code. I am not a Freightliner guy but if it is showing no engine, I would say the engine ECM is not booting up at key on and the ABS is recognizing this. Your auto trans will not allow the engine to crank if it cannot communicate with it. Everytime you key on the engine ECM will turn on the yellow check engine light and the red stop engine light for a bulb test. If you turn on the key and you do not see these lights come on that means the engine ECM is not powering up. If the they do turn on I would say you have a datalink problem between the ECM and other devices.
