WOYO CTB00715 OBD 2 CAN Tester Box 12-24V w/ 59-inch Cable for Auto Diagnostics

Product Overview

The CAN Tester Box is a versatile CAN bus circuit tester compatible with 12V and 24V systems. Designed for automotive diagnostics, it ensures safe and efficient testing of the OBD port (DLC) before connecting other diagnostic tools, preventing damage from wiring faults.

Key Features

1. 1. Pre-Connection Error Detection

   • Tests the DLC (OBD-II port) for faults like pin shorts and reverse polarity before linking diagnostic devices.

2. 2. Real-Time Signal Display

   • Visually monitors communication signals (e.g., protocol signals) on assigned pins, enabling fast fault localization—replacing manual multimeter voltage checks.

3. 3. 16-Pin Rapid Connectivity

   • Full access to all 16 OBD-II pins for streamlined vehicle diagnostics and repairs.

4. 4. Voltage Monitoring & Alerts

   • Safeguards during ECU flashing by monitoring OBD input voltage, with high/low voltage alarms.

5. 5. Robust Protection

   • PTC self-healing fuse (overload protection) + Reverse polarity protection (LED turns red on Pins 4/5).

Target Applications

• OBD Port Pre-Check – Avoid damage to scanners from faulty wiring.

• CAN Bus Troubleshooting – Identify protocol signals or pin issues instantly.

• ECU Flashing Safety – Voltage monitoring prevents bricking during updates.
  

Why Choose This Tester?

✅ Preventive Diagnostics – Catch wiring errors before they harm expensive tools.
✅ Time-Saving – No more multimeter checks; signals are displayed in real time.
✅ Wide Compatibility – Works with 5 major protocols (CAN, ISO, KWP, etc.).

Notes for Clarity

• DLC = Diagnostic Link Connector (standard OBD-II port).

• PTC Fuse = Resettable polymer fuse for overload safety.

• Reverse Polarity LED alerts on Pins 4 (GND) & 5 (Signal GND).
