As a 2014 Jeep Compass owner, understanding your vehicle’s On-Board Diagnostics II (OBD2) system is crucial for maintaining its health and performance. When that pesky check engine light illuminates on your dashboard, it’s your Jeep’s way of telling you something needs attention. But fear not! This comprehensive guide will empower you to understand and interpret those cryptic OBD2 codes, specifically for your 2014 Jeep Compass.
This article will delve into how to retrieve these codes without a scanner using the “key trick” method, and provide an extensive list of potential OBD2 error codes your 2014 Jeep Compass might display. Remember, this information is intended as a troubleshooting aid and not a substitute for professional diagnosis and repair.
Understanding OBD2 and Your 2014 Jeep Compass
The OBD2 system is standard in all cars manufactured in the USA from 1996 onwards, including your 2014 Jeep Compass. It’s designed to monitor various systems in your vehicle, from the engine and transmission to emissions control. When the system detects an issue, it stores a Diagnostic Trouble Code (DTC) and often illuminates the check engine light.
While a professional mechanic uses sophisticated OBD2 scanners for diagnosis, you can retrieve basic codes yourself using a simple “key trick”. This can give you a preliminary understanding of the problem before seeking expert help.
Retrieving OBD2 Codes on Your 2014 Jeep Compass: The Key Trick Method
For 2014 and newer Jeep Compass models equipped with a digital odometer, you can typically retrieve OBD2 codes directly through the instrument cluster display. Here’s how:
- Start with the ignition off. Ensure your Jeep Compass is turned off completely.
- Push and hold the odometer reset button. Locate the odometer reset button on your instrument panel and press and hold it down.
- Turn the ignition key to the “RUN” position. While still holding the odometer reset button, turn your ignition key to the “RUN” position. This is the position just before you would start the engine. Do not start the engine.
- Release the odometer reset button. After turning the key to “RUN”, release the odometer reset button.
- Observe the odometer display. The odometer will cycle through a series of displays, often showing dashes or numbers (e.g., 111111, 999999), followed by the vehicle’s serial number. After this sequence, any stored OBD2 error codes should be displayed, often starting with a “P” (for Powertrain codes).
If this method doesn’t work for your specific 2014 Jeep Compass, you can also try the OBDI style “key trick” method, although it’s less common for OBD2 vehicles:
- Start with the ignition off.
- Within five seconds, switch the key ON, OFF, ON, OFF, ON. “ON” is the “RUN” position, and “OFF” is not “LOCK” but simply turning the ignition off. Do this sequence relatively quickly.
- Watch the check engine light. The check engine light will begin to flash. Count the flashes. Two flashes, then a pause, then three flashes would indicate code 23. A long pause separates codes if there are multiple. Code 55 indicates the end of the code sequence and is normal.
Important Notes on Code Retrieval:
- Parking Brake: In some instances, you might need to engage the parking brake for the codes to display correctly.
- Code Repetition: Codes are generally not repeated. If you see “55 55” in older models using flashing lights, it’s likely just a single “55” (end of codes).
- Limp Mode: If your 2014 Jeep Compass’s computer detects a major malfunction, it might activate “Limp In” mode. This is a safety feature that allows you to drive the car to a repair shop, often with reduced power and functionality (like losing 3rd or 4th gear in automatic transmissions).
2014 Jeep Compass OBD2 Error Codes: Decoding the Meaning
Once you have retrieved the codes from your 2014 Jeep Compass, you’ll need to understand what they mean. OBD2 codes are standardized across most manufacturers, but this list is particularly relevant to Chrysler vehicles, including Jeeps.
Below is an extensive list of OBD and OBDII codes. Note that some codes may be more relevant to older vehicles (OBDI) or Chrysler vehicles in general. For the most accurate diagnosis for your 2014 Jeep Compass, always consult a professional mechanic and refer to a specific OBD2 code database for your vehicle model.
