Note:

This technical bulletin covers testing and repair procedures for multiple vehicle lines, model years and engine

combinations. To prevent mis-diagnosis, you must ensure that the testing/repair procedure is applicable to the

vehicle you are servicing.
Technical Background

The VAS6161, MCR340V, In-Charge 940 (INC-940), and GRX3000VAS are the only VW approved battery testers

and chargers that can be used to test and charge batteries in VW vehicles. Use of non-approved battery testers

and chargers is not allowed, as internal battery damage may occur.
Production Solution

 Connect battery tester.
Tip:

Cable has (+) and (–) stamps on each terminal. Positive (+) terminal is a larger diameter than Negative (–)

terminal. DO NOT attempt to force the wrong terminal of harness onto a battery terminal if it does not fit.

1. Connect cable with positive (+) stamp to inner positive (+) terminal of 1st battery. When doing so, ensure that

the other end of the cable (negative) does not make contact with ground or any object. Tighten to 6Nm.

2. Connect the negative (–) terminal of the cable to the inner negative (–) terminal of the 2nd battery. Tighten to

6Nm (53 in. lbs).

3. Connect Midtronics tester positive (+) clamp (red color) to outer positive (+) terminal of 2nd battery.

4. Connect Midtronics tester negative (–) clamp (black color) to outer negative (–) terminal of 1st battery.

When testing/charging is completed:

1. Remove Midtronics tester negative (–) clamp (black color).

2. Remove Midtronics tester positive (+) clamp (red color).

3. Remove battery cable negative (–) connection at 2nd battery negative (–) terminal.

4. Remove battery cable positive (+) connection at 1st battery positive (+) terminal.

Tip:

Two 6-volt batteries are connected in series to achieve 12-volts, the same current value will flow through each

battery. As a result, only use a DIN value of 380A, DO NOT double or halve this value when entering data into

Midtronics tester.

If DIN rating is not shown:

 Use SAE value as printed on battery label.

If using SAE value rating:

 Midtronics tester menu option must be changed to achieve accurate results.

 A change from DIN to SAE can be made from the “Other” menu option on Midtronics tester.

When testing or charging battery installed in vehicle:

 DO NOT Test/Charge from Remote Location (3.2L).

 (3.2L) DO NOT use remote location (+) -arrow-.
 (3.2L) DO NOT use engine bracket (-) -arrow-.

Testing/Charging from Remote Location (Reduced DIN Rating Requirement)

When using remote location terminals -arrows-, located in engine

compartment, always reduce DIN rating on MCR340V, INC-940,

VAS6161 and GRX3000VAS testers.

 3.6L, and 4.2L engines: 270 DIN.

 3.0L TDI, 5.0L (TDI) engine: 295 DIN.

 MY2011-2017 3.6L engine: 295DIN

cannot be tested or charged via remote location in engine

compartment. To test or charge starter battery, go directly to

battery terminals.

Tip:

Use of these reduced DIN ratings are required to compensate for the internal battery manager and/or the

extended length of cable due to battery location.

2-7 MCR340V, VAS6161, INC-940, GRX3000VAS Trouble Shooting Error Messages

MCR340V / INC-940 Displays "System Noise" at Beginning of Test

MCR340V and INC-940 may display "System Noise" at beginning of battery test when testing directly at battery.

This is an infrequent and a normal message which may be caused by:

 Ignition left in "ON" position.

 Accessories or loads turned ON, with key in "ON" position.

 Loads running with ignition switched "OFF" such as: cooling fan or after-run coolant pump.

 Aftermarket equipment (due to improper installation), such as entertainment, security, remote starters,

televisions, lighting, etc.).

This may be overcome by verifying:

 Ignition is switched "OFF".

 All loads (cooling fan or after-run coolant pump) are OFF prior to testing.

 Any aftermarket equipment is disconnected from vehicle's electrical system.

Wait a few minutes, and then retest battery again.

Battery Testing Results: Midtronics MCR340V, VAS6161 Analyzer vs. INC-940, GRX3000VAS Charging

Station

In some cases, when testing a battery using the MCR340V tester:

Test results may be “Good Battery - Recharge”.

However, when attempting to charge the same battery with INC-940 Charger:

Results may be to “Replace Battery” either after testing or during charging process.

Tip:

This is normal since MCR340V, VAS6161 and INC-940, GRX3000VAS use a conductance test, but the INC-940,

GRX3000VAS also incorporates use of a 150A load test and ”sophisticated” charging algorithm which monitors

charging state of the battery.

In this case, results of INC-940, GRX3000VAS should always be used instead of MCR340V or VAS6161.

Testing/Charging: INC-940 Charging Station -Automatic ModeWhen using INC-940 Battery Charging Station in “Automatic Mode”, and testing or charging a deeply discharged

battery:

INC-940 may continuously display a message “Are clamps connected?”

In order to test battery:

 Manually charge battery for 30 minutes and perform test again.

Testing/Charging: INC-940 Charging Station -Manual ModeWhen using INC-940 Battery Charging Station in “Manual Mode”, and testing or charging a deeply discharged

battery:

INC-940 may display a message “Are clamps connected?” twice.

This is not a result of defective INC-940 test equipment, but is a safety feature of the INC-940 to ensure cables are

connected to battery before power is turned ON.

INC-940 Charging Station Always Displays “Check Connections”

INC-940 may constantly display a message to “Check Connections” after cables are connected to battery

terminals.

This is most likely due to the sensing probe making contact with the clamp.

Tip:

There is one sensing probe on each clamp, (+) and (-), make sure to check both!

 There must be no contact between the inside connection and

outside jaw of clamp -arrows-.

 Inside connection is bent and touching outside of the clamp, arrows-.
If clamp is incorrect:

 Use a small flat tool and gently bend sensing probe so it does not make contact with clamp.

If this does not resolve the issue:

 Contact Midtronics Corporation Customer Service Department at 1-800-776-1995 for assistance.
