Smart OBD-II Diagnostic Box

The Smart OBD-II Diagnostic Box (SODB) is a perfect partner to scan tools, code readers, monitor readers or data loggers. It automatically checks any abnormality on OBD2 port caused by shorting (i.e Pin 16 Power shorted to Ground), reverse polarity and any other abnormalities that will occur and detects the type of communication protocol used in the system.

It functions as Protocol detector and break-out box for the DLC (Diagnostic Link Connector) with additional features! By connecting this tool, the technician can switch, cross, and parallel interface leads simultaneously to diagnose, analyze, test and monitor the whole testing process on a vehicle. It has LEDs that light up to display protocol detected, grounds, and voltage. It serves as DLC magnifier (makes DLC 5 times larger), DLC extender (place DLC where needed) and a “spy” (monitors the activity on each OBDII dedicated data line).  It monitors voltage with a display and an alarm warning when the voltage falls below 12 Volts or goes higher than 15 volts. It can also be used as a data saver when connected to an external 12V battery while replacing the vehicle's battery.

Exclusive Invention

1. TEST OBD2 PORT BEFORE PLUG IN SCANTOOL

It performs tests on all the 16 pins of OBD2 port for abnormality caused by shorting, reverse polarity, etc to avoid damage to your scan tool prior plugged in.

2. MONITOR VOLTAGE DURING REFLASH PROGRAMMING

It has voltage monitoring feature with Volts display which will give an alarm warning when the voltage falls below 11.8V or higher than 15.2V (for 12 V System) or below 23.8V or higher than 29.2V (for 24V system) while doing programming or coding.

It constantly monitor battery voltage with volts display and warning beeps for Low (Below 12V) and High (Above 14.9V) – an important feature for ECU programming and coding operations.

3. As Power Backup for ECU (Keep Alive Memory (KAM) chip) while replacing car battery

Connect the OBDII cable with battery clips to SODB. Turn ignition key to OFF position and connect the tool to the car DLC. Attach the battery clip to an external battery (not the battery from the same car). If the external battery voltage is above 12V, the battery volt indicator LED on the Data saver cable will light up.

Unique Features / Application

1. Voltage monitoring

-        the voltmeter will display voltage input with alarm beeps

For 12V system:  one at a time for 30 sec when the voltage falls below 11.8V.

For 24V system:  twice at a time for 30 sec when the voltage falls below 23.8V.

2. Testing of the 16 pins individually

It detects any voltage present on Car Manufacturer designated pins No.1, 3, 8, 9,11,12 & 13 (yellow colour socket) and OBD2 assigned protocol pins 2, 6, 7, 10, 14, 15 (blue colour socket), other than pins 4 (Chassis), 5 (Signal) for grounding (black colour socket) and pin 16 (red colour socket) which is positive supply 12V or 24V.

Signal indicator: Steady/ Fast/ Slow blink

The LED on individual pin will blink slow, steady and fast to indicate whenever there’s voltage (positive or negative) detected at any particular pin and triggers the ‘Voltage Present’ or ‘Check’ LED to illuminate as a warning.

If there is a reverse polarity occurred, the green LEDs at pin 4 (Chassis) and pin 5 (Signal) ground turns into red color.

Low/ High Voltage Alarm beeps

The voltmeter alarm ‘Beeps one at a time for 30 sec’ if voltage falls below 11.8V (for 12V system) or ‘Beeps twice at a time for 30 sec’ if the voltage is below 23.8V (for 24V system)

3.  Jumper cable: for direct pin to pin or stacking connection while scanning or perform special functions and tests.

4.  Blink Code Cable - N/O (Normally Open) contact switch cable for Reset, Adaptation or codes activation.

5.  As DC Power source for other devices

Tap +12V or +24V depending on the power input at the DLC connector red banana socket (pin 16) and Chassis Ground (-) at black banana socket (pin 4) to power other DC loads.

How to Use:

1. General use

a. Switch the ignition key to OFF position.

b. Connect the tool to the DLC on vehicle.

c. Turn ignition key back to ON position.

d. As soon as it powers up, the voltmeter will display the battery volts and automatically checks the power, grounds, DLC data wires and searches for voltage pulses.

2. Detecting Protocol in use

a. Plug scan tool or interface to the tool.

b. Use the scan tool to view live data stream.

c. Check the flashing blue LEDs and match them with the protocols marked on the label of the tool.

d. Always turn ignition key to OFF position before removing the tool.

3. Act as Data Saver

a. Connect the OBDII cable with battery clips to the tool.

b. Turn ignition key to OFF and connect the tool to the car DLC.

c. Attach the battery clip to an external battery (not the battery from the same car).

d. The tool will display the battery voltage and now it is ready for replacing the car battery.

e. After the job is done, remove the battery clips from the external battery and unplug the tool from the car.
