I can send you the diagnostic flow charts and connector end views for the code P1518, but you will need an advanced scan tool and a DMM to follow the steps. Recently in the past couple weeks I have noticed that when I get on the gas and any speed the truck seems to hesitate all the way through accelerating and even at steady speeds on the highway. This serial data circuit is separate from any other serial data circuit on the vehicle. P1114 Engine Coolant Temperature (ECT) Sensor Circuit But, the logic is simple: the ECM commands the starter relay to crank the engine and, with the exception of the voltmeter being sourced from the ignition switch, the operating information displayed on the instrument cluster is relayed to the cluster via a data bus from the ECM. make a purchase, we may earn a small commission.
