    I have freightliner columbia 07 detroit s60. Tractor abs light comes on on dash "abs 136 code", whet it shutdowns the engine. I turn of the key wait couple seconds turn it back on , start the engine and after awhile it shutdowns engine again. The voltage on dash drops to 0.0v and after awhile backs to 14v. I was at the shop , they checked battery connections, ground, starter wiring everything clean, alternator charges fine too. I brought truck to freightliner dealer, they just hooked laptop to see check engine codes but didnt find anything. Does anybody had anything similar or have any idea what this could be?

    It has nothing to do with the ABS, I would be looking at the fuse panel under the passenger side dash panel. I would be looking at the power wires and grounds, and the dash relay and fuses for a dirty connection, from a spilled drink. When it happens test with a test light.
    Just a thought!

    Check all ABS related wiring as well as the ECM side where the wire meets. Let me know if you want a wiring diagram for the ECM

    ABS can't shutdown the engine directly, but if there is a short somewhere, it will trigger the circuit breaker which will shut everything down.
