CAN Bus Termination Checklist Form
Complete this checklist to verify proper CAN bus termination, wiring, and signal integrity. Use this form for practical inspection and documentation during CAN bus installation or maintenance.
All CAN bus wiring connections are secure and properly routed.
*
Completed
Correct number of termination resistors (typically two, one at each end) are installed.
*
Completed
Termination resistor values measured at each end are within specification (e.g., 120Ω ±5%).
*
Completed
No short circuits detected between CAN High (CAN_H) and CAN Low (CAN_L) lines.
*
Completed
No open circuits detected in CAN bus wiring.
*
Completed
CAN bus voltage levels are within acceptable range (typically 2.0–3.0V for recessive state).
*
Completed
No evidence of signal reflections or waveform distortion observed on oscilloscope.
*
Completed
All CAN connectors are properly seated and free of corrosion or damage.
*
Completed
Shielding (if present) is connected to ground at one point only.
*
Completed
CAN bus passes communication test (devices communicate without errors).
