Car & Truck Diagnostic Box

When the scan tool fails to establish communication with a vehicle, the OBDII system seems not responding, or a CAN-Bus system related fault code is registered, you need to begin testing at the communication link.

The Car & Truck Diagnostic Box (CTDB) is a tool which connects to a vehicle's OBDII connector and is used to easily diagnose electrical faults and CAN bus line activity.

It detects communication protocol, checks power and ground circuits, check active protocol lines, or connect a multimeter or oscilloscope for detailed signal analysis. 

Also, it provides battery voltage monitor with numeric display. It provides an alarm warning when voltage drops below 11.9v for 12V and below 23.8V for 24V battery, the beeper will sound. The same goes for detected high charge voltage of 15V for 12V battery and 30V for 24V battery

The concept of this Car & Truck Diagnostic Box is simple - it provides standard banana plug connection points to all lines in the J1962 OBDII connector, which allows connection to individual lines on an OBDII connector easily and securely.

Exclusive Inventions

1. LCD Display 

This Break Out Box comes with LCD display (instead of replaceable faceplate) with button keys that allow user to choose the vehicle manufacturers Pin-out designations based on the vehicle to test.

Unique Features

1. Voltmeter - it comes with Digital LED display to show voltage of the vehicle battery.

 With an Alarm warning beeps

         ·  Low Voltage Alarm Beeps - it provides short beeps when voltage detected is below 11.9V for 12V battery and 23.8V for 24V battery.

        ·  High  Voltage  Alarm Beeps - it provides long beeps when voltage detected is 15V for 12V battery and 30V for 24V battery.

2. Adapter/ cable

This Break Out Box comes with connecting cables/ adapters which consists of OBD2 16 pin to  9 pin (J1939) type 1 or type2 or 6-pin (J1708) to connect the Diagnostic Link Connector (DLC) of non- OBD vehicle e.g.  trucks, tractor, with different pin designation. 

There are four main types of diagnostic ports, 6-pin (J1708), 9-pin (J1939) type 1 & 2, and OBDII’s.

Generally light and medium duty trucks use OBDII ports whereas heavy duty trucks use 6-pin or 9-pin ports.

It supports the following vehicles’ DLC:

·       OBDII – 16 pins connector:

Chrysler (Type A, B & C), Ford Truck, General Motors, Volvo Truck, SAE J1962 and ISO 15031-3 (Type A & B).

·       Deutsch – 9 pins connector:

Paccar, Freightliner Cascadia, Deutsch J1939 and Type 2 (500K Baud Rate)

·       Deutsch – 6 pins connector:

J1708 / J1587 HD

Functions

First, determine the connector type of the vehicle (16 pin, 6 pin, or 9 pin).

Install the required adapter/ cable in order to establish connection with the Car & Truck Diagnostic  Box.

For direct connection to the Break Out Box:

 i. If the vehicle has a 16-pin data link connector, no additional cable is required.

ii. If the vehicle has a 6 or 9 pin data link connector, use the appropriate cable and install on the Diagnostic Breakout box cable end.

1. Connect to Oscilloscope

2. Auto detect communication Protocols

3. Monitors Data Stream

4. Checks alternator condition - quick reference check of voltage charge during idling and high RPM conditions.

5.As Break-out Box function - can check voltage, resistance, frequency, pulse width or duty cycle using lab scopes, multimeter, logic probes and etc.

6. OBD Memory Saver – maintain power supply to OBD system when replacing weak battery

Other Features

·   12V/24V compatible

·   Displays different Vehicle Manufacturers and its pin-outs designations 

·   LED Signal Display - ECU signal voltages trigger the LEDs to light up.    

·   DC Power Source - as power source for other devices that need external power (up to 5 amperes )    ·   with reverse polarity and overload protection with self recovery fuse

Optional  

  ·   Replaceable Face Plate
