Sep. 02 2023

Vehicle: 1999 Dodge Ram 2500, 4WD, L6-5.9L DSL Turbo, VIN 6, Automatic Transmission/Transaxle

Mileage: 226,562

Problem: The owner’s complaint with his Ram was that it stalled a few times while driving, then it would crank but not start. There was also a "NO BUS" message displayed in the odometer field of the instrument cluster.

Case Details: Initial checks by the technician discovered that fuse #3 (20A) in the power distribution center (PDC) was blown. It was replaced but blew again. A closer inspection revealed there was rodent damage to the harness, and circuit A40 (RD/LG wire) shorting to ground.

Confirmed Repair: The technician repaired the wiring damage and replaced the blown fuse. The engine cranked right up and ran fine. Easy Fix!
