Description
BREAK OUT THE BOX – The OTC 3413 CAN Test Box!
Connect, Detect, Monitor Voltage and more.
Use the OTC 3415 CAN Test Box for diagnosing electrical faults and CAN bus line activity. Check power and ground circuits, check active protocol lines, or connect a multimeter or oscilloscope for detailed signal analysis.
Breakout Box and Protocol Detector
- Connects between Diagnostic Link Connector (DLC) and scan tool
- Detects data and protocol communication
- Monitors system voltage – Display and high/low alarm
- Connect leads for increased diagnosis, analysis, and monitoring
Useful Functions
- Verify ECU activity
- LEDs at pin-out display signal detection, Flashing LEDs for ECU activity
- Monitoring of OBDII data lines
- Probe lines with scope or multimeter for detailed signal information
- Check & monitor battery voltage
- Continuous numeric display or voltage
- Alarm warning when voltage drops below 11.6v or rises above 15.2v
