History data check results should be attached to a technical DISS query for vehicles which are covered by
manufacturer’s warranty, extended warranty or parts warranty.
Should the vehicle not be covered by any form of warranty or the vehicle type is not as described there is no
requirement to supply the battery history data check results.

To access battery history data. Navigate to Guided Functions, open Diagnostic Address 19, and select
Battery History Data to access the information in ODIS-S.

Note to Product Support
Only second level DISS queries for battery related issues on vehicles which are covered by manufacturer’s
warranty, extended warranty or parts warranty
•

Provide full battery history data from the gateway.

•

If a quiescent battery drain is suspected, carry out an overnight battery draw test using an oscilloscope
and attach the recorded results to a Technical DISS query.

In cases where a battery replacement is required under warranty, the operative MUST raise a Technical
DISS query and request authorisation before proceeding. Ensure all required information is included, as
missing data may invalidate the warranty claim.
Note to Product Support: The DISS query MUST be second levelled to the Electrical TM to gain permission
to replace the battery if the vehicle is covered by manufacturer’s warranty, extended warranty and parts
warranty.

Should the battery not be covered by extended or parts warranty please continue with diagnosis / battery
replacement as required.

Warranty accounting instructions
Should the battery have failed due to a system fault / high quiescent drain, the battery can be claimed as an
additional consequential part to a warranty claim, the system fault must also be detailed as well as
confirmation of the actual system fault repair.
All battery claims must be supported by the relevant battery test codes.
Always refer to the battery testing procedure information in ElsaPro maintenance manuals.
The battery fitted to the vehicle is a deep cycle battery. Warranty will only be honoured on battery
replacement when the irreparable deep discharge has been caused by an electrical fault on the vehicle or a
manufacturing fault within the battery itself.

Note: Failure to provide the battery history data will invalidate the warranty claim.
