If the problem persists where you have to fire up the engine again and again and then turn it off to shut the whole thing down, there are a couple of reasons to look at.

Reasons & Solutions Behind Ignition Or Accessory On Message

There are two common reasons why the “Ignition on Accessory On” may appear, and there are easy solutions. 

Reason 1: Faulty M27 Fuse

If the M27 fuse is blown, it can cause the vehicle to lose power, resulting in the “Ignition or accessory on” message appearing on the vehicle’s display. This means the fuse is not working to supply power to the ignition system, which would turn the ignition off.

If the fuse is removed and reinserted without any change, the vehicle must be taken to the dealership for replacement. Excellent and reliable Jeep fuse services are available, but check out how the solution works. 

Solution: Replace The M27 Fuse

Installing a new M27 fuse in a jeep involves a few actions. This is something mechanics do quickly. The process works like this:

  • First, locate the fuse panel and remove the panel cover.
  • Then, locate the old M27 fuse and remove it using a fuse puller or a pair of needle-nose pliers.
  • After that, insert the new fuse into the holder with the metal prongs facing downwards.
  • Ensure the fuse is fully inserted and secure before replacing the panel cover.
  • To finish the replacement process, a significant amount of rotation and unscrewing is required. If you are comfortable with it, you may be able to do it yourself.

Reason 2: Faulty Ignition Switch

The faulty ignition switch can cause the electric system not to be able to send the proper signals to the operating system. The warning message will continue to display because the ignition cannot be switched off due to a fault. 

It is essential to have the problem with the vehicle diagnosed correctly and the necessary repairs done to avoid any more potential issues. An experienced mechanic should inspect the car and complete the required repairs.

When replacing an ignition switch, it is essential to take proper safety precautions and follow the points outlined to ensure that the replacement is done perfectly. 

This is how the process works:

  • Disconnect the negative cable from the battery to avoid any potential electric shock.
  • Remove the upper and lower steering column covers.
  • Remove the mounting screws, and unplug the wiring harness from the ignition switch. And then, pull the ignition switch out of the steering columns.
  • Insert the new ignition switch, and plug the wiring harness back into it.
  • Replace the upper and lower steering column covers, and reconnect the negative cable to the battery.
  • When the whole process is completed, test the new ignition switch to ensure the installation is working correctly.
