How To Check Check Engine Light Codes Without A Code Reader
If your 2015 Ram 1500’s check engine light comes on, try checking for codes without a code reader. Start by turning the battery off and then reconnecting the negative cable. This simple step may help you identify and address the issue causing the check engine light to illuminate.
Disconnect The Negative Cable
When your check engine light comes on in your 2015 Ram 1500, it’s important to diagnose the issue as soon as possible. But what if you don’t have a code reader? Don’t worry, there is still a way to check the check engine light codes without a code reader. One simple step is to disconnect the negative cable from your car’s battery.
Here’s how you can do it:
- Pop open the hood of your truck and locate the battery. It’s usually located near the front of the engine compartment.
- Identify the negative terminal, which is marked with a “-” sign. It’s usually connected to a black cable.
- Loosen the nut or bolt that secures the negative cable to the battery terminal.
- Once the nut or bolt is loosened, carefully remove the negative cable from the battery terminal. Keep in mind that you should only be disconnecting the negative cable, not the positive cable.
Reconnect The Negative Cable
After disconnecting the negative cable, you’ll want to reconnect it to the battery terminal. This step is crucial for resetting the check engine light codes.
- Hold the negative cable near the battery terminal and align the connector to the terminal.
- Tighten the nut or bolt that secures the negative cable to the battery terminal. Ensure it is secure but not overly tightened.
