How to use
1.
Switch the ignition key to OFF position.
Connect
the OBD Link Connector to the DLC on vehicle. Turn ignition key back to ON
position. As soon as it powers up, the voltmeter will display the battery volts
and automatically check each of 16
pins of the diagnostic port in the case of stable state event or in the case of
single impulses.
2.
LED indicator
Once the
test is completed in less than 10 second, the result will be shown.
3.
As Power source:
While connected to the car DLC, you can tap +12V at the red banana socket (pin 16) and Chassis Ground (-) at black banana socket (pin 4) to power other DC loads. Capacity rated at 5 Amps.
4.
Detecting Protocol in use:
Plug your
scan tool or interface to OBD Link connector to view live data stream. Check
the flashing LEDs and match them
with the protocols marked on the label of the OBD Link Connector Always turn ignition key to OFF position before removing
the tool.
5.
Act as Data Saver:
Connect the OBDII cable with battery clips to OBD Link Connector. Turn ignition key to OFF and connect the tool to the car DLC. Attach the battery clip to an external battery (not the battery from the same car). The OBD Link Connector will display the battery voltage and now it is ready to proceed for replacing the car battery. After job done, remove the battery clips from the external battery, unplug the tool from the
car.
6.
Check Alternator charging condition:
With ignition key in OFF position, plug OBD Link Connector into the car DLC. Switch key to ON position and the tool will display the battery voltage. Start the engine; observe the voltage display while the engine is idling. It should be above 12.6 Volts. If not, check for loose drive belt. Then rev engine up to 3,000rpm and observe the change in voltage. If the voltage is above 15.2 Volts, the alarm will beep indicating that the charging voltage is too high. In this case, the regulator needs to be
checked. Then switch ON all electrical loads, rev engine to 2,000rpm and observe the changes involtage at the tool. The voltage should above 13.6 Volts. If the voltage is below, check for loose drive belt and the Alternator.
Some
Typical Applications:
VW - To protect the Scan tool such as aftermarket
radios on VW's.
GM - Transmitter Programming on some GMs.
Honda - Set the ECM in SCS mode with your scan tool
connected.
Lexus - Help diagnose electronics systems (Sirius,
GPS) on pin 6 and 14 Bosch - Troubleshoot Bosch controllers that short to
ground.
Proton - needs to short pin 1 to ground in order to
access into OBD2 functions.
Toyota Avanza - the base RPM can only be achieved by
shorting pin 4 and 12
LEDs
Activity:
OBDII Protocol Detector & Breakout Box LEDs allows
you to keep tabs on power and ground. It identifies the protocol used in the
vehicle.
1.
RED LEDs (Pin 16) - automatically turn-on as soon as
you plugged into DLC.
RED LEDs
turn dim when:
Low
battery voltage - refer to Voltmeter and alarm will beep (below 12V).
Wiring to
DLC pin 16 is faulty
Grounds
circuits has resistance issues
2.
GREEN LEDs (Pins 4 and 5) - automatically turn-on as
soon as you plugged into DLC. Ground LEDs (Pin 4 and 5) is connected to battery
voltage through pin 16. Therefore, a
ground supply on pin 4 will not affect LED 5. A dim single green LED will
indicate a circuit problem with the corresponding circuit.
3.
3. BLUE LEDs (Pins 2, 6, 7 and 10) - LEDs should flash
when serial data voltage pulses are present in the data line. Blue
LEDs is assigned
on pins 2,
6, 7 and
10 to indicate
communication with scan
tool or interface
and for communication protocol
identification. It will turn-on depend on your vehicle model. For some vehicle model, none or multiple blue
LEDs will turn-on as soon as our Breakout Box is connected and you start the
ignition. The brightness of the LEDs depends on the nature of the signal it's
pursuing. This Breakout Box can indentify immediately the protocol used. The better way to indentify the protocol in
use is to set-up the scan tool or interface in to LIVE DATA. This will lead in
a constant data stream between the scan tool and the vehicle, and then you can
locate the LEDs that are flashing.
4.
4. YELLOW LEDs (Pins 1, 3, 8, 9, 11, 12, and 13) - it
should flash when your vehicle manufacturer use either one on the pins for any
function they prefer.

Pins listed as "Discretionary" indicate that
the vehicle manufacturers may used them for specified purpose. Check with the
manufacturer's specifications for these connections. For voltage and current
limits, refer to SAE J1962 (ISO 15031-3.3). Test tool must not draw more than
1.5 amps through the pin number 5 (Signal ground).
Helpful
Tips:
When activating some ABS and diagnostics wires to
recover flash code, you can use pin 4 or pin 5. To power small DC loads with
maximum 5 Amps you can use pin 16. If red (power) and green (grounds) LEDs
turned dim or flickering when you plugged a scan tool supplied via DLC, it indicate
a problem with your vehicle wiring that causes the voltage to drop.
