Introduction
Thank you for your purchase of the LS1M Scanner.
The LS1M Scanner is a scan tool that can retrieve engine parameters and trouble codes from GM vehicle using the
VPW OBD-2 protocol. That includes most GM cars & trucks from 1996 to 2006. To verify compatibility of your
vehicle to the LS1M scanner, look for the diagnostic connector under the dash, on the driver’s side. It’s a 16-pin
connector with pins 1-8 across the top & pins 9-16 across the bottom. The VPW protocol uses pins 2, 4, 5 & 16, so
these positions should have a metal insert present.
LS1M has been optimized for use in GM’s LS1 and L67 series engines. Enhanced data parameters for these engine
types are supported; there’s a list of them in the appendix. Some of these enhanced parameters will also work on
other GM vehicles.
The basic LS1M scanner comes with an OBD2 interface cable, software CD and this User’s Guide:
