GDS BATTERY DIAGNOSIS FUNCTION
Description: This bulletin is issued to provide the extended battery diagnosis procedure using
GDS. This battery diagnosis function displays the various battery-related faults such as:
• Internal short circuit
• Battery deterioration
• Malfunction of electronic parts
• Insufficient battery charge
• Normal battery
• Charging defect
Battery diagnosis uses the battery sensor history saved for the last 30 days and ICU diagnostic
communication to track battery state of charge (SOC) and current parasitic draw history.
IMPORTANT
The below listed models must be tested by the GDS Battery Diagnosis.
Battery claims may be subject to chargeback if submitted with the wrong tester code.
Applicable Vehicles:
• 2019MY~ G70 (IK)
• 2021MY~ G80 (RG3)
• 2023MY~ G80 Electrified (RG3 EV)
• 2023MY~ G90 (RS4)
• 2023MY~ GV60 Electrified (JW1 EV)
• 2022MY~ GV70 (JK1)
• 2023MY~ GV70 Electrified (JK1a EV)
• 2021MY~ GV80 (JX1)

For a discharged battery the following battery
charge performance test may be requested
to perform R03 diagnosis:
a) GDS shows the battery charge
performance test is required.
Select OK to acknowledge.
b) Start the vehicle either by running
engine or Ready On to attempt charging
of the battery.
IMPORTANT
Remove the jumper/booster box
immediately from the battery
after starting the vehicle, and
before selecting OK to begin the
charging performance test.
c) Select OK right after starting the vehicle
and removing jumper/booster to the
battery.
i
Information
Make sure vehicle is running and
select OK should you get this battery
low confirmation message:
d) The GDS battery charge performance
test will be run for 5 minutes and the
actual progress time will be displayed
on the test screen.
e) Wait until the progress time reaches 5
minutes of vehicle run test, then the
GDS will automatically complete the test
and display one of the test results
shown in the below pages.

f) After 5 minutes the test result will
display. The progress of the battery
charge performance is displayed on a
3rd graph showing current (Amps) of
charge the battery accepted over the 5
minute vehicle run time.
(this example shown is for a good
battery that took a charge).
i
Information
Contact Techline if you get a D03/D04
result but find the battery is unable to
recover after a full charge attempt.
Upload the following to STUI before
