SEAL KIT- 1937620 - Caterpillar

This diagnostic code becomes active when all of the parameters for the CAN data link for the left rear upper medium range radar are missing for more than 250 milliseconds. This diagnostic code is associated with the wire harnesses that connect to the components for the Cat Object Detection System (Cat Detect). Failure of the internal CAN data link wiring of a Cat Detect component may also cause this diagnostic code. This failure causes the data link communications to be disrupted.System Response:Cat Detect is disabled. The system will reactivate when all of the parameters on the CAN data link are available. The status indicator for the system will illuminate red.Test Step 1. CYCLE THE POWER TO THE SYSTEM
