This diagram bridges the vehicle chassis with the engine manufacturer's dedicated electronic module (e.g., Detroit Diesel CPC/MCM modules or Cummins ECM). It outlines critical paths for the throttle pedal position sensor, ignition keyswitch signals, and engine data links. 3. Aftertreatment System (ATS) Wiring

: Many faults (like a non-functional gauge or a warning light) stem from communication problems. A verified diagram will show the CAN bus topology, including termination resistors. This allows you to check the network's resistance and signal integrity, which is critical for modern diagnostics.
Specific diagrams for engines like the Detroit Diesel DD13 or DD15 detail the sensors (NOx, DPF, SCR) and module connections.
