1996 Chevrolet Chevy K Pickup Ignition Coil Control Circuit High Voltage

Filed Under (Chevrolet (Chevy)) by admin on 21-12-2013

Download 1996 Chevrolet Chevy K Pickup – 4WD | Chevy Pickup, GMC Pickup, Suburban, Tahoe, Yukon (VIN C/K) Service Manual DTC P1351 Ignition Coil Control Circuit High Voltage. Circuit Description The enhanced ignition system uses the crank sensor in order to provide the timing input to the VCM. The VCM uses this reference pulse in order to determine the individual ignition spark timing for each cylinder. Once the VCM calculates the ignition timing, the ignition coil module on the IC circuit receives the timing signal. Each timing pulse received by the ignition coil module on the IC circuit triggers the coil module in order to operate the ignition coil. The secondary ignition voltage is induced, and then the secondary ignition voltage is sent to the distributor for distribution to each spark plug. This DTC is a type A DTC. The IC signal voltage ranges from about 0.5 volt to 4.5 volts.… Read More

Seville/STS/DeVille Any other GM Vehicles with the VATS or PASSKey II system (If your ignition key looks like the one pictured below.) 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.… Read More
