ECAN ID 1629 Diagnostic Message Reporting an Unknown ID

SPN 625/FMI 14

DescriptionMotor Control Module (MCM) system ID Erratic, Not Received or Stopped Arriving at Common Powertrain Controller (CPC).

what this means that the cpc cab computer and the engine computer are intermittently are loosing communication via the can network,

historically we rewire the can network from the engine ecm (mcm) and the cab computer (cpc)

the wires are small and over time they start to break down most commonly when sand gets into the loom and starts chaffing the wires,

let me know if you have anymore questions
