Precaution on Operation
zThe appliance is a sophisticated electronic device, never have it clashed
when in use.
zMain unit screen may flash at the moment of engine ignition, which is
normal.
zYou may unplug the main unit if the program can not be actuated or
confused screen occurs. Plug again to continue the operation.
zMake sure the appliance is properly connected to the DLC to avoid
communication interruptions.
zDuring operation, keep the screen upward and leveled.
zBe careful when plugging and unplugging the main cable and diagnostic
connector. Tighten the screw before operation to avoid unexpected
disconnecting and/or damage to the port.
zHandle with care.Avoid collision. Unplug the power after operation.
zUnplug the power cableby holding the connector, not the cable itself.

1. Foreword
1.1 Product summary
X-431 GDS is a new generation of sophisticated and
integrated automotive diagnostic product with colorful screen and powerful
functions developed by LAUNCH.
It provides an optional function of automotive battery test, which adopts the
latest state-of-the-art conductance testing technology in the world and can test
vehicle’s battery status. Two testing environments (Inside the Vehicle and
Outside the Vehicle) are available and applicable to battery test. In addition to
battery test, charging system and actuation system test can be done while
Inside the Vehicle is selected.
It supports various battery standards and specifications, including CCA, DIN,
IEC, EN, JIS, SAE and GB etc. It is specifically designed to help car owner,
repair workshop, battery factory use battery test instrument properly and
determine whether the battery is normal or not.
1.2 Scope
Battery test aims to check starting plumbic acid storage batteries for vehicles,
ship, boats and aviations, etc. It can test all kinds of batteries complying with
CCA, DIN, JIS, EN, GB and SA standards. For detailed test standards, please
refer toTable 1-1.

Standards Standard (Full name) Test capacity range
CCA Battery Council international 100～1700
DIN Deutsche industry normen 100～1200
JIS Japanese industry standard 26A17～245H52
EN Europe norm 100～1700
IEC National electrical commission 100～1200
GB Chinese national standard 100～1200
SAE Society ofAutomotive engineers 100～1700
1.3 Capability standard for vehicle battery test
The rated capacity range for vehicle battery varies with different test standards.
See Table 1 for details. If not specified, the rated capacity value is defaulted as
100～1700.
CCA：100～1700
DIN：100～1200
EN：100～1700
IEC：100～1200
GB：100～1200

2. Test environment and structure
2.1 Test environment
Inside the vehicle test indicates that the battery connects to loading devices,
such as engine, etc. After doing battery test, it can perform charging system
and actuation system test, which is proceeded as a whole simultaneously.
Charging system and actuation system test is not required but must not be
performed before battery test. Because it is difficult for vehicle technicians to
judge where is faulty exactly if they have the faintest idea of battery’s status
itself.
Outside the vehicle test indicates that the battery is disconnected from all
loading devices on vehicles. Therefore, only battery test is supported in this
condition.
2.2 Battery status and description
There are mainly 5 states as follows:
No. States Descriptions
1 Good battery Indicates battery is normal.
2 Replace
battery Indicates that battery is aged or becomes rejected, or
battery life cycle approaches to be exhausted. In this
case, battery voltage appears to be normal, but battery
itself is not well, i.e. battery polarity board has been
completely vulcanized or aged. Please replace battery
immediately.
3 Good-recharge Stands for lowbattery. The battery is good itself.
4 Charge-retest It is better for a few batteries to be fully charged before

testing in order to avoid judging in error under special
conditions.
5 Bad cell Indicates one of the battery cells is bad and can not
work normally, but for which one is bad, it can’t be
verified. In this case, battery voltage is generally lower
than 11V, mainly resulting from internal circuitry
damage, such as short circuit, open circuit, dummy
weld etc.
2.3 Batterybox structure and test accessories

3. Connections & Operations
3.1 Connection
Connect one end of the A/B cable to the B type USB terminal of the batterybox,
and then connect the other end to the USB port of GDS main unit. This
connection applies to outside the vehicle test and inside the vehicle.
Notes:
1. Wait about 10s and begin to communicate since the batterybox needs to
initialize after connection is complete,otherwise, communication may fail.
2. Red lamp on the batterybox means it has been successfully powered up; If
the green light is always on, it indicates the clip is well connected; while the
green light blinks, it indicates that the clip has poor contact. Do not perform
any test until the clip andA/B cable are properly connected.
3.2 Inside the vehicle test
Battery test andcharging system & actuation system test canbe done in this
mode.
3.2.1 Battery test
1. Enter battery test main menu, and select a desired test environment as
shown in Fig. 3-1.

Fig. 3-1
Button Descriptions:
[System]: 3 submenus are available: Show desktop (return to desktop),
Version (view the current version info) and Exit program (exit the
current program).
[Help]: views introduction and operation guideline for battery test.
[Next]: proceed to thenext operation.
[Reset]: stop all current operation and enter initializing interface.
Note: The sequences of inside the vehicle and outside the vehicle test are
almost the same, but under inside the vehicle condition, all loads in vehicles
must be powered off for getting an exacttest value.
2. Firstly, detect whether floating electricity exists or not before testing. If yes,
turn on the headlamp to remove it. Otherwise, the system starts test
program directly.

Select [Battery testing] > [Inside the vehicle], then click [Next], the system
starts detectingfloating electricity automatically.Ascreen similar to Fig. 3-2
appears if floating electricity is detected.
