CLAIM FORM DATA
For the battery checks and eventual replacement to be done under warranty, it is mandatory to
attach all the result print-outs from the diagnosis equipment to the repair order, as described in this
Service News.
For the new Mopar Battery Tester instrument it is no longer necessary to print and attach the
receipt. Make sure that the instrument is connected to the Internet via a W-iFi network and that at
the end of the verification it has sent the result to the specific site in the cloud.
NOTE: Operations performed under warranty will not be refunded if the test results are not
printed, even if this is due to an insufficient level of charge of the internal buffer
battery of the test equipment in the event of a completely flat vehicle battery.
NOTE: The presence of non-genuine Mopar system or accessory device (electrical/
electronic) not installed according to the technical specifications of the manufacturer
will invalidate the warranty of the battery and/or of other concerned systems or
components.
