It can be alarming when something lights up on your dash, especially if it looks like a warning sign or symbol.
If you see the red warning bolt on your Jeep dashboard, it usually indicates that there is a problem or fault with the ETC (Electronic Throttle Control).
In this guide, I am going to discuss what steps you should take if you see this symbol and what you can do to fix the problem.
Let’s take a look.
What is The Red Lightning Bolt Warning?
A sensor kicks in when the throttle is opened, which measures the pressure. The clever technology sends a signal from the pedal to the engine throttle via a motor.
If the red lightning bolt is appearing on your dashboard, chances are, there’s a communication error.
However, don’t panic too much. If the warning light appears while driving, you do not need to pull over immediately. However, it’s best to get your car to a mechanic at the next available opportunity, where they can correctly identify the problem.
Resetting The Red Lightning Bolt Warning Sign
In some cases, the red lightning bolt might be because of a potential fault rather than a current one. For instance, if the pedal position has altered. If this is the case, there are steps you can take to perform a reset to get rid of the lightning bolt.
- Turn on the ignition (but do not start the car).
- Slowly put pressure on the gas pedal before returning it to the resting position.
- Start the vehicle.
- Try pressing the gas again to see if the lightning bolt goes off.
What Causes The ETC to Malfunction and How To Fix?
The ETC might have malfunctioned due to a fault with the electrical circuit. If this is the case, it’s a pretty easy fix as long as you know what you’re doing and if you have a multimeter.
However, if you’re unsure, it is best to be looked at by a trained mechanic to ensure you don’t cause further damage.
If you are handy in this area, you can follow the steps below to repair the issue.
- Locate and examine the fuse box.
- From here, you’ll need to use your multimeter to check for any loose connections.
- When the meter reads zero, you’ve found your loose connection.
- At this point, you’ll need to replace the Jeep’s dashboard and rewire all the connectors.
