Warranty Battery Test Types and Description for the VAS 6161
Inventory Test: Use this test mode only for vehicles in dealer inventory before the customer warranty
start date.
Warranty Test: Use this test mode only for vehicles under the current customer vehicle warranty. VIN
number input and battery information is a mandatory input for proper claim submittal. Always provide the
battery test code for all battery warranty claims.
Service Test: This test IS NOT to be used for any warranty battery testing. It is designed for out of
warranty battery testing only and for customer pay maintenance.
Note: For PDI vehicles, use only the GRX3000VAS for testing as per the PDI check list and the
‘Ready Set Go’ documents on ServiceNet.
2-7 VAS6161 and GRX3000VAS Trouble Shooting Error Messages
VAS6161 and GRX3000VAS Displays "System Noise" at Beginning of Test
VAS6161 and GRX3000VAS 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 VAS6161 Analyzer vs. GRX3000VAS Charging Station
In some cases, when testing a battery using the VAS6161 tester:
Test results may be “Good Battery - Recharge”.
However, when attempting to charge the same battery with GRX3000VAS Charger:
Results may be to “Replace Battery” either after testing or during charging process.
Tip:
This is normal since VAS6161 and GRX3000VAS use a conductance test, but the 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 GRX3000VAS should always be used instead of VAS6161.
Testing/Charging: GRX3000VAS Charging Station -Automatic ModeWhen using GRX3000VAS Battery Charging Station in “Automatic Mode”, and testing or charging a
deeply discharged battery:
GRX3000VAS 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: GRX3000VAS Charging Station -Manual ModeWhen using GRX3000VAS Battery Charging Station in “Manual Mode”, and testing or charging a deeply
discharged battery:
GRX3000VAS may display a message “Are clamps connected?” twice.
This is not a result of defective GRX3000VAS test equipment, but is a safety feature of the GRX3000VAS
to ensure cables are connected to battery before power is turned ON.

GRX3000VAS Charging Station Always Displays “Check Connections”
GRX3000VAS 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-.
