The computer in your Dodge truck generates and stores error codes related to critical vehicle component systems. When your Dodge truck generates one of these codes, a Check Engine Light will illuminate on the dash. This light can indicate a variety of problems. Ironically, only several codes pertain to the actual engine in your truck. Many of the codes can indicate a problem with the transmission, emissions control system and even the fuel system. To erase the code and get the light to go off, you will need to reset the computer. This will involve cutting the power to the computer.
Step 1
Open the hood and loosen the retaining nut connected to the battery cable clamp that is attached to the negative battery terminal.
Step 2
Slide the negative battery cable clamp off the battery terminal.
Step 3
Wait five seconds then slide the battery cable clamp back over the negative battery terminal. The Dodges computer will now be reset.
Tighten the retaining nut on the cable clamp to secure the clamp to the battery. On some Dodge trucks, you will need to drive an additional 500 miles from the time you cut power to the computer for the Dodges computer to fully reset.
