NOTICE
This technical bulletin is applicable up to 12 months in service or 12,000 miles (whichever comes first).
Customer reports one or more of the following conditions is present or has occurred:
•

The remote control key buttons do not work.

•

The vehicle does not start unless the key is held against the steering column.

•

The vehicle cannot be unlocked/opened from the outside with the remote control buttons.

•

The following message appears in the instrument cluster: "Replace key battery”.

•

The following message appears in the instrument cluster: "Key battery low”.

One or more of the following DTCs may be stored in the -J519 - Central Electrics Control Module (BCM) (diagnostic address 09).
•

B147918 – Remote key 1 Voltage too low (static or sporadic).

•

B147A18 – Remote key 2 Voltage too low (static or sporadic).

•

B147B18 – Remote key 3 Voltage too low (static or sporadic).

In vehicles equipped with KESSY, a message pertaining to the key battery condition may be displayed in the instrument
cluster without setting one of these DTCs.

Technical Background
There is no specification for testing the open circuit voltage of key batteries. Open circuit voltage testing using a voltmeter will result in
misdiagnosis of the actual key battery condition.

Production Solution
Not applicable.

Service
If diagnosis leads to the key battery as the suspected cause of the remote key concern, it is necessary to check the key battery using the
applicable Guided Fault Finding (GFF) test plan.
Only replace the key battery according to the GFF test plan result. The completed GFF Test plan must be uploaded to Volkswagen via
GFF Paperless or retained by the dealer (electronically or otherwise), as it may be subject to request. The measurements in the test plan
must be performed using a VAS 6356 test instrument box connected to the ODIS tester (results obtained from manual entry of
default values into the test plan are not valid).
Locating the test plan:

•

Key battery diagnosis is performed using the GFF test plan “0009 – Remote control battery check”.

•

If the test plan was attached automatically based on DTCs, click “Perform test” to begin.

If the test plan was not attached automatically, it will be necessary to locate and add it manually.

•

Click “Select self-test” (1).

•

Click the magnifying glass icon (2).

•

Then enter “Remote control battery” as the search term (3).

•

Select the result “0009 – Remote control battery check” (4).

•

Click “Go to” (5).

•

Select the test plan “0009 – Remote control battery check” (6).

•

Click “Attach to the test plan” (7).

•

Once the test plan is attached, select it, and click “Perform test”.

It is also possible to find the test plan by drilling-down through the self-test selections as follows:
Diagnosis-capable systems >0009 – Vehicle Electrical Control Module System > 0009 – Functions, Electronic central electric
> 0009 – Remote control battery check.

Overview of the test instrument setup for voltage measurement in the test plan:
The test plan will require setting up the test instruments to provide 320 Ohms across the key battery during the voltage measurement.

During the GFF test plan, the VAS 6345 resistor decade will be used together with the VAG 1594/19A extension leads.
•

The voltage measurement is performed within the test plan, using the VAS 6356 test instrument box.

•

The resistance will be validated within the test plan before proceeding to measure voltage.

•

The free ends of the leads are held against the positive and negative sides of the key battery during the voltage measurement.

Overview of identifying the key remote data:
The following data will be requested within the GFF test plan (see examples below):
•

The brand name of the battery.

•

The part number of the remote control.

•

The manufacturing date of the remote control in WW/YY format.

Identification of data for Hella remote key.

Identification of data for Continental remote key.

Identification of data for FS19 remote key.

Warranty
If a key battery is replaced, a completed GFF test plan must available to support the claim.
