Before You Order And Use
Before You Order And Use
This product connects directly to the vehicle data link. Use it only when the target circuit, OBD2 pin, and test operation are understood and confirmed safe.
Connect To Vehicle DLC
Connect the breakout box directly to the vehicle OBD2 diagnostic link connector to access the diagnostic communication pins.
Monitor Signal Access
Check protocol, power, and ground access through the 16-pin breakout interface during diagnosis.
Test With Multimeter / Oscilloscope
When an uncertain signal is detected, connect a multimeter or oscilloscope through the input jack for further testing.
Use DC Power Carefully
Use the DC 8-30V jack for ECU backup power only when the vehicle circuit and operation are confirmed safe.
Warm Tips
