Mercedes-Benz TSB #LI54.10-P-071499

2018 Mercedes-Benz C300

TSB Document:

Affected Component: ELECTRICAL SYSTEM

Summary
Complaint The result from the XENTRY battery test does not match the current state of the battery. Cause The XENTRY battery tester uses the stored on-board electrical system data in the SAM module to access the health of the 12 volt battery. The XENTRY battery test may not take into account a single discharge event because the SAM cannot record the data if the battery is discharged. Note: A discharged battery does not necessarily need to be replaced. A discharged battery may be recovered with no permanent damage. Remedy Follow guided tests as described.
