뭐가 문제인지 도와주세요

 

All doors, including the trunk, cannot be opened with the remote control.
The trunk switch inside the car and the lock button on the center console also do not work.
I checked all the SLCM/security fuse/driver wire door actuators and also replaced the remote control battery, but there is no signal.
Only the Reader / Exciter ecu cannot be checked. I can't find where the ECU is. Not found.
Are there any models without an ECU?

Please help me what is wrong

 

The security lock control module is located fwd of the trunk car's left hinge a little inboard of the fuel fill cap

You will have to remove the fwd facing trunk panel

The SLCM will be mounted at a slight angle with 4 connectors that are grouped to look like 1 long one

Do not remove connectors without removing positive battery cable

Had any heavy rain lately as there is a drain that cloggs and the SLCM connectors may have got wet

There are a few TSBs to see starting with section 18

315 or 433 hz ?

Fuse # 4 trunk fuse box

Are 2 different FOBs doing the same thing , if so points away from being a FOB issue

 

I would ask "does the car lock and unlock manually, each door and trunk, using only the key?"

I'm not intimately familiar with the x300, but can you perform an "all doors lock" using the key? I'd ask if that is working as well...withOUT using the FOB.

I would start by unplugging and replugging back in the door lock relay, IF the x300 has one similar to the XJS. The XJS uses DAC4862 and is problematic on both my 96 cars. Unplugging it and plugging it back in always restores it.

If not, the Security ECU (which I know the x300 does have) might be damaged? I haven't read about that being a common problem though.

Lastly, the remote locking feature getting wonky is usually indicative of a failing battery for the XJS I have owned. How old is the battery?

 

The Fob batteries can easily be put in backwards and best to use a high quality brand battery

Vee is mentioning the main car battery wich is important also in the security system

With a 315 hz system you have many external to the security lock control moule relays located is this pic

With the later 433 system you don't have these relays

See page 28 , left heelboard relay area
