How to bypass the VATS (PASSKey II) system in a late model GM vehicle

Pontiac 1994-1996 Grand Prix 1992-1999 Bonneville 1993-2002 Firebird/Trans Am/Firehawk Buick 1994-1996 Regal 1992-1999 LeSabre 1991-1996 Park Avenue 1991-1996 Roadmaster Oldsmobile 1994-1997 Cutlass Supreme 1992-1999 Eighty Eight/LSS/Ninety Eight/Regency 1991-1996 Custom Cruiser Wagon Chevrolet 1995-1999 Monte Carlo 1995-2001 Lumina 1993-2002 Camaro 1986(?)-1996 Corvette (C4) Cadillac How to bypass the VATS system in a late model GM vehicle Bullet-Style” solderless connectors Heat Shrink Tubing Resistors of varying values (totalling the resistance measured across the key’s “pellet”) Alright, let’s begin the madness: 1. Take your DMM, set it to measure Ohms (use the 20k setting.) Measure the resistance across the pellet of the ignition key. Place one probe on the silver part of one side of the pellet, and the other probe on the other side. Write this value down. 2. Purchase a resistor or resistors that add up to the value measured in step 1. Radio Shack is a great place to go for the resistors, heat shrink tubing, and the “bullet-style” solderless connectors. 3. Take the 16 ga. wire and cut into 2 four-inch pieces. 4. Strip off approx 1/16″ of insulation off each side of both wire pieces. 5. Put your resistors together in series (or if you’re lucky and have a chip that has a resistance that matches a single resistor) and solder one wire to one end of the resistor(s) and the other wire to the other side. Example: You measure 11.72 on the 20k (k meaning kilo or 1,000) scale. The closest match is 11.801 which is a #15 “chip.” Always remember that resistors have a tolerance of 2%, meaning the resistance value of the “pellet” can be either 2% higher or 2% lower than 11.801 k ohms (11.72 falls in tolerance range.) You will want to aim for 11,801 ohms. So when you go to Radio Shack you want to pick up a 10,000 ohm (10k,) a 1,000 ohm (1k,) and an 800 ohm resistors to wire together in series to achieve the 11.801k ohm value.

1989-1996 Dodge Dakota Trucks COIL Ignition Tests Manual

Dakota Trucks 1989-1996 Ignition Tests COIL The ignition coil for the vehicles covered by this guide is in the following locations: • 1989-92 engines: mounted to the firewall • 1993-96 2.5L engines: mounted on the thermostat housing in front of the coolant temperature sensor • 1993-96 V6 and V8 LDC engines: mounted to a bracket bolted to the right engine cylinder head • 1993-96 5.9L HDC engines: mounted to a bracket bolted to the air injection pump (AIR pump) mounting bracket. Fig. 2: Ignition coil mounting-all 1989-92 models Fig. 3: Ignition coil wiring and mounting hardware-1993- 96 2.5L engine 1. Inspect the ignition coil for arcing while the engine is running. If the engine will not start, this can be performed while the engine is cranked by either an assistant or a remote starter. Look at the coil in dim or low light to aid visibility of any arcing. Fig. 4: Ignition coil mounting-1993-96 3.9L and 5.2L/5.9L LDC engines 2. Arcing at the tower will carbonize the wire boot, which, if it is connected to a new ignition coil, will cause the coil to fail. In such cases, clean all the carbonization away or replace the components as necessary. Fig. 5: Ignition coil mounting-1993-96 5.9L HDC engine 3. Using a coil tester or ohmmeter according to the manufacturer’s instructions, test the primary and secondary resistance. Replace any coil that does not meet the specifications indicated in the accompanying chart. 4. Inspect the secondary coil wire for any sign of damage. Replace if any damage is found. Carbon tracking on the old wire can cause arcing and the failure of a new ignition coil. REMOVAL & INSTALLATION 1989-92 Models See Figures 6 and 7 1. Disconnect the negative battery cable. 2. Disconnect the three wires from the coil. Mark them to identify for installation. Fig. 6: Remove the coil bracket bolt at the cowl Fig. 7: Unscrew the coil mounting hardware, then remove the coil from the vehicle 3. Unplug the condenser suppressor connector from the coil, if equipped. 4. Unbolt and remove the coil. To install: 5. Bolt down the coil with old bolts. 6. Connect wires to coil making sure that the proper wires are connected where they should be. 7. Connect the condenser suppressor, if equipped. 8. Connect the battery negative cable Removal and Installation V6 AND V8 ENGINES 1. Disconnect the negative battery cable. 2. Disconnect the primary wiring from the ignition coil. 3. Disconnect the secondary spark plug wire from the coil. 4. Remove the two bolts and withdraw the coil from its mounting bracket. To install:
5. Position the coil on its bracket and install the two bolts. Tighten them to 100 inch lbs. (11 Nm). If the bracket has been tapped for coil mounting bolts, these fasteners require less torque, so tighten them to 50 inch lbs. (5 Nm). 6. Connect all wiring to the ignition coil. TESTING See Figure 1 The only test you can perform without a DRBII scan tool, or equivalent, is a basic check of the sensor only.

Various Concerns With Shifter and/or Ignition Key (Replace Shifter Assembly/Shifter Components or Ignition Lock Cylinder )
