GM VATS/Passkey bypass circuit
This module is used to replace the original GM VATS PASS-Key module and resistor key. The module will generate a PASS-Key or Pass-Key II fuel enable signal for the ECM. The module will not bypass the starter interrupt that is present on some vehicles, and will not provide any anti-theft protection. The primary use for this item is for engine swaps or when repair/replacement costs for the OEM system are cost prohibitive. The most common symptom of PASS-Key lockout is when the engine will repeatedly start and run for about 1 second and then shut off. This unit will work for many GM engines up to about 1995 including the 3.8 and 3800, 3.4 TDC/DOHC, Cadillac 4.5, 4.9, and Northstar, Chevy TPI and LT1. It will not work for the newer PASS-Key III, VTD, and CTD systems.
Small size, approx. 1" x 1" x .75" not including mounting tabs
Easy three wire hookup
User selectable jumper for PASS-Key or PASS-Key II systems
Solid state circuitry assembled on double layer printed circuit board
Epoxy encapsulated for vibration and moisture resistance.
