For example, with a key fob in hand, the tool can display the last eight digits of the VIN of the associated vehicle, making it easy to match the fob with a vehicle in the dealership\u2019s inventory or a vehicle in for service.<\/span><\/p>\n<p class=\"western\"><span style=\"font-size: 12pt;\">The EL-52545 tool works with the new Vehicle Intelligence Platform electrical architecture on the 2020 Corvette, CT5 and CT4 as well as with electrical architectures on 2008 and later GM models. The tool also has the ability to service non-GM vehicles, providing support for the dealership\u2019s used vehicle department.<\/span><\/p>\n<p class=\"western\"><span style=\"font-size: 12pt;\">The EL-52545 TPMS and RF tool package includes the TPMS Module, USB and RJ45 cables, power adapter, OBD II module and a hand strap.

The EL-52545 tool changes TPMS relearn communication from radio frequency to writing IDs directly via the Diagnostic Link Connector (DLC) without any time penalty when doing a normal tire rotation. As long as the tool is placed by the proper tire, an incorrect sensor cannot be learned, greatly reducing a common issue of learning a stray sensor on a near-by vehicle.<\/span><\/p>\n<p class=\"western\"><span style=\"font-size: 12pt;\">The Rotate\u2013Diagnose\u2013Relearn (RDR) function of the EL-52545 tool can be used anytime the TPMS or tires are serviced on a vehicle, such as a tire rotation or if the TPMS warning lamp is illuminated.
