Sytem error 23

The method of deactivation depends upon which of two different alarm systems is in your vehicle. Each system requires a different method. The two systems: enhanced and basic. If the car will not crank while the alarm is going off, you are dealing with the enhanced system. A small red LED is on the left side of the dash. Hold it down (depresses only slightly) while turning the ignition key to the start position. The starter should engage. Relese the key.

With the basic system, the car cranks but the alarm continues. use the key to unlock the dirver's door, or both doors, or both doors and the tail gate.

The immobilizer system has become "confused" by the disconnection. If one of these two methods above has worked, you need read no further.

Probably one of the following procedures actually "confused" the system: https://www.wikihow.com/Reset-a-Factory-Car-Alarm. That falls under no good deed goes unpunished.

There are also other methods sometimes attempted: https://www.wikihow.com/Reset-a-Factory-Car-Alarm.

The sad reality is that different brands have different deactivation methods: https://www.2carpros.com/articles/how-to-reset-a-security-system

But back to YOUR vehicle, You would think your user manual would give you some guidance regarding the immobilizer.

If you have a keyless fob, it can be used to disarm either system by pushing the unlock button on it while the alarm is going off.

Could be problem with ground maybe they both are using same ground wire and it is loose or broken somewhere.

Most all aftermarket radios have their own fuse next to the wiring harness plug. Depending on the brand, it may only take a few minutes to pull the radio out of it's sleeve to check for the fuse. Usually, you can pop off the trim ring to see what you are working with.

This is a wild guess, but disconnect the positive terminal from your battery. Touch the cable (that went to the positive) to the negative, to drain out any capacitor in the system that is holding charge. I think you have to short it that way for about 10 seconds. Reconnect cable to positive and start car.

That will reset your computer and should reset the alarm as well.

Find your alarm module, it is a black, rectangular box with an antenna wire on one end. Remove any ties or fasteners holding the alarm in place and take it out from under the dash.
All you need to do is simply remove the two connected wires to the ignition switch, and connect it with the car side of the two together. This enables the ignition switch and that enhances the control over the starter again, without hindrance.

Besides the obvious jokes about gas in the bathroom, I would advise you move it out of the bath room. It is being affected by excessive moisture causing errors in the sensors. The same can happen for smoke alarms with condensation or other moisture sources. It should be located relatively close to a possible source of problem, but not right on top of it.

Is the shower in use at around 7 am every AM?

put key in door lock,unlock/hold key over windows will go down....then lock/hold key over,windows will go up,press and hold unlock button on remote for 30 secs,you have just reset the alarm/immobiliser.

Opening the trunk with the key (not the valet key) will shut off the alarm.

Can't offer help on permanently disabling the alarm.

Is it an aftermarket alarm/starting system? If so it may be burnt out. Without the right bosch relays to hold the locks down for 3 seconds the sytem will burn out trying to lock and unlock due to the air pump sytem. They might have also messed with the stock alarm system if you have it on your model which would compound the problem. If the car starts at all I would look at replacing the coil and coil wires as they are some of the biggest contributors to poorly running MB's. Then I would check the fuel pressure, maybe replace the fuel filter and check valve as they can keep fuel pressure low. After that might be a bad ignition switch which I doubt but anything is possible. If you also have an aftermarket radio it is tied into the stock alarm and that may not help your issues either. Hope I have given you a good place to start.
