General Motors GM-38522-A Variable Signal Generator
Kent-Moore Tool Number: J-38522-A
Designed for diagnostic use on 2-Mode Hybrid Trucks and SUVs, as well as 6L80/6L90 transmissions—including those found in the 2014 Corvette—the GM-38522-A Variable Signal Generator is an essential tool for troubleshooting transmission systems.
It simulates the output of the auxiliary pump controller and speed sensor by generating pulse-width modulated (PWM) signals at known frequencies. This allows technicians to isolate the source of Diagnostic Trouble Codes (DTCs) through a process of elimination, aiding in efficient repair or component replacement.
