Technical Background
In order to determine the root cause of the drained battery, additional information from the vehicle is required.
Production Solution
Not applicable.
Service
Please ensure that the battery is not drained due to an external influence:

• Parking the vehicle for a prolonged amount of time without a battery maintainer being attached (>90
days).
• Non-OEM accessories being attached to the vehicle that may use electrical power while the vehicle is

Technical Service Bulletin
• Replacement of drained or damaged batteries due to external influence is not applicable to warranty
and claims regarding such cases may be denied.
Please ensure that the vehicle batteries are at an acceptable state of charge when the vehicle arrives at
the service center.
• If the vehicle is parked for a prolonged amount of time (for example, waiting for parts), periodic (at
least monthly) checks should be performed regarding the battery’s state of charge.
• If the battery’s state of charge is below 80%, the battery should be recharged immediately.
Any time a 12V battery (A) needs to be replaced, the following procedure must be performed before installing the
new 12V battery (A):
Please connect a 12V battery charger.
Note: In some cases, the battery may be too low to allow the battery charger to start up. In such cases, the
charger can be started by “jump starting” it by connecting jumper cables from a good battery to the damaged
battery for a moment while the charger is connected. (The jumper cables only have to be touched to the poles as
the vehicle charger needs to see an initial voltage to start up. They can be taken off as soon as the vehicle
charger starts charging.)
Please perform the following test plan in ODIS:

ODIS will now output the battery history data on the screen and store it to the GFF log.
For example, that data may help you to determine if the drained battery may be caused by misuse or external
influence, for example:
Section 5 – Energy critical conditions.
• Displays certain parameters when the vehicle wasn’t able to be started due to a low 12V battery, like if the
transmission was in Park during the time the vehicle was discharging the battery, if any lights were on during
that time, if the ignition was left on, etc.
Section 7 – Energy balance standing
• Displays the time and battery discharge that the vehicle was parked. According to the owner’s manual, the
customer is responsible to service (charge) the 12V battery after one month of the vehicle not being driven.
Should an entry here show a duration of last standing time of more than ~750h, combined with a large battery
discharge and under-voltage time under section 1, the battery may be defective due to an external influence.
Warranty
Please claim the GFF time required to perform this TSB on the claim requiring the battery replacement.
