Volkswagen Golf Variant / Jetta. Manual - part 467

 

 

If the test was performed at the battery jump start terminal and

the message still does not go away, then perform the test directly

on the Battery - A- .

2.7

Battery Test with Vehicle Diagnostic

Tester

Special tools and workshop equipment required
♦ Vehicle Diagnostic Tester
The Battery - A- can also be checked using the Vehicle Diagnostic

Tester when it is installed and without being connected to a bat‐

tery charger.
Test Prerequisites
♦ No battery charger connected
♦ Battery - A- is connected.
♦ Battery temperature at least +10 °C (50 °F).
Procedure
– Connect the Vehicle Diagnostic Tester . Refer to

⇒ “1.2 Connect the Vehicle Diagnostic Tester ”, page 89

 .

– Select 

Guided Fault Finding

.

– Use the 

GO TO

 button to select the “function/component se‐

lection” and the following menu options one after the other:

♦ Body
♦ Electrical Equipment
♦ 01 - OBD-capable systems
♦ 61 - battery monitoring
– Follow the instructions in the display.

Current Draw Test

WARNING

Do not check or charge a Battery - A- when the visual indicator

has »no color or is bright yellow«. Jump starting must not be

used!
There is a risk of explosion during testing, charging or jump

starting.
These Batteries - A- must be replaced.

Make sure the correct charging mode is set on the battery charger

so the current draw test is not inaccurate.
♦ Battery Charger - VAS5095A- . Refer to

⇒ “3.1.3 Battery, Charging with Battery Charger VAS5059A ”,

page 32

 .

♦ Battery Charger - VAS5900- . Refer to

⇒ “3.2  Battery Charger VAS5900 ”, page 37

 .

♦ Battery Charger - VAS5903- . Refer to

⇒ “3.3  Battery Charger VAS5903 ”, page 48

tery condition of discharged Batteries - A- , a conclusion can be

made during the charging process using the Battery - A- current

draw as to whether the Battery - A- should be replaced or charged

completely.

Note

In the case of the Battery Tester - VAS6161- , the current draw

test must always be conducted when the test result “conduct cur‐

rent draw test” appears in the display.

The current draw test should always be performed if the test using

the Battery Tester with Printer - VAS5097A- had the following re‐

sults:
1 - Starting power sufficient
2 - Starting power insufficient
3 - Starting power very insufficient
4 - cannot be tested - charge the Battery - A- and perform the

test again

5 - Battery Tester with Printer - VAS5097A- does not turn on

(no LED, no printout)

Depending on the test results Battery Tester with Printer -

VAS5097A- (refer to 

⇒ “2.4.7 Test Result Evaluation”, page 17

 ),

additional test steps or work for a clear evaluation of the battery

charge must be made.
By checking a current draw capacity on a Battery - A- during the

charging procedure, it can be determined in a short time whether

a partially discharged or severely discharged Battery - A- can be‐

come operable again by further charging. Refer to

⇒ “3.7 Severely Discharged Batteries”, page 68

 .

Test Prerequisites
♦ When charging a battery, the temperature of the battery must

be at least 10 °C.

♦ The charger must be able to deliver at least 30 A charge cur‐

rent, such as on the Battery Charger - VAS5095A- / Battery

Charger - VAS5900- / Battery Charger - VAS5903- .

♦ When charging with the Battery Charger - VAS5095A- , the

Battery - A- current draw must be measured using a current

probe ( Test Instrument Set - Current Clamp - 100A -

VAS6356/4A- ).

♦ The Battery Charger - VAS5900- and the Battery Charger -

VAS5903- indicate the current draw. The Battery Charger -

VAS5900- automatically performs the menu- guided current

draw test.

Procedure
– Connect the Battery - A- to the Battery Charger and start the

charging process.

– Measure the Battery - A- charge current after five minutes.
Test Result
The charge current must be above 10% of the nominal capacity

5 minutes after charging begins.

5 minutes after charging begins.
– Charge the Battery - A- completely when the charge current is

greater than 10% of the nominal capacity.

– Let the Battery - A- sit for two hours and then perform the bat‐

tery load test. Refer to 

⇒ “2.4.3 Battery Load Test”, page 13

 .

If the charge current is less than 10% of the nominal capacity (less

than 6 A for a 60 Ah battery) five minutes after starting the charg‐

ing, then replace the Battery - A- . Refer to ⇒  Electrical Equip‐

ment; Rep. Gr.  27 ; Battery; Battery, Removing and Installing .
– In warranty and Goodwill cases, fill out the battery test sheet

and keep it with the Battery - A- .

Battery, Checking Resting Voltage, Ve‐

hicles in Storage or Inventory

Special tools and workshop equipment required
♦ Analog/Digital Multimeter - FLU83III-

WARNING

Risk of injury. Follow all warning messages and safety pre‐

cautions. 

Refer 

to

⇒ “1.3 Warnings and Safety Precautions”, page 3

 .

The resting voltage may only be measured on vehicles in storage

or inventory within the scope of the prescribed maintenance and

care work as an assessment criteria for the Battery - A- condition.
The resting voltage measurement serves to determine whether it

is necessary to recharge the Battery - A- on vehicles in storage

or inventory. Refer to Maintenance Tables “Service for Vehicles

in Storage or Inventory”.
Test Conditions
The Battery - A- may not be charged or discharged for at least

two days.
Procedure
– Measure the Battery - A- resting voltage using the Analog/

Digital Multimeter - FLU83III- .
