Code Reader Not Connecting To Truck Computer. You can do a quick test to find out. Find out what is causing the engine. With your truck off, put the key in and turn it on (but don't start the truck), then turn it back off. Nothing is tied into the pcm from that switch. You can try scanning the truck with a different scan tool to verify whether it's the scan tool or the truck. If you have the car with key icon when trying to start it mean the chip is not being detected. If it does it on another tool. The oil pressure switch (not a sensor) feeds directly to the instrument cluster (dash) gauge. I asked previously but you didn't. I have a cheapo code reader that will pick up the obd port in this truck just fine, it won't give you more than basic diagnostic and probably won't help with an abs light but it. I have an 04 sierra and the obdii port doesn't want to communicate with the computer when a scanner or programmer is.
