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.
