Diagnose The Problem Causing Limp Mode:
Before you can get your Jeep out of limp Mode, you need to diagnose the problem causing it to enter it. Here are some necessary steps you can take to diagnose the issue:
- Check for diagnostic trouble codes (DTCs): DTCs are codes stored by the vehicle’s computer that indicate the source of the problem. You can retrieve these codes using an OBD-II scanner, which you can purchase at an auto parts store.
- Inspect the engine: Look for signs of damage, such as leaks, and check the oil level.
- Inspect the transmission: Check the transmission fluid level and look for any signs of leaks.
- Inspect the electrical system: Check for damaged wires or loose connections.
How to Fix Limp Mode?
Due to its complexity, the limp Mode can only be resolved using a scanner that scans codes stored in the car’s computer. All fluids must be clean and at the proper level for troubleshooting.
To find out which sensors or parts need to be replaced, use an OBD/OBD2 scanner.
But remember that an item is only sometimes defective just because it reads poorly on a computer. A damaged or broken wire may be the source of a false signal.
Wires from a sensor or other component producing false data can have their conductivity tested using a multimeter. If electricity flows through a portion of the wire but not to the sensor, the wire needs to be changed.
