Toyota Avensis 1.8 auto 2003 - Remote central locking - BRISTOL

The following failed simultaneously:

Remote central locking, interior lights, radio. satnav screen,"lights on" warning bleeps - ALL FAIL.

Also the trip meter readings revert to zero when engine switched off.

I have removed and re-inserted the black box integration relay and PROBLEM REMAINS.

All interior light bulbs are OK. All fuses are OK.New battery in key fob.

I can centrally lock all doors with key and the car functions correctly in all other respects.

Can you suggest a solution to the problem?

Disconnected the battery, but did not cure the problem.

Thanks for your reply (the solitary response!

Are there any Toyota experts out there with diagnostic skills??

is there a 'plug-in' diagnostic aid that would pinpoint the problem?

As stated, all fuses are OK, as are all light bulbs.

I can use the car except for remote locking, sat-nav . radio and clock.

There must be a simple explanation?

Is there more than one fuse box on this model?Also I have found on many modern car fuseboxes ,a blown fuse can be very difficult to identify without removing the fuse as they are installed very close together.Just a thought.hth

Thanks

I totally agree that the most obvious answer is a problem with a fuse, but all fuses have been declared intact on 3 seperate occassions. There are indeed 2 fuse banks.

Thanks for your input.
