Hello to all and thank you to all that reply i have a R A M cat 1 alarm and imobilizer fitted just being out to my car and all my hazard lights are flashing but no horn as i would hear if some one had try to force it, if a take out the fuse under bonnet they stop flashing have replaced with spare fuse but no difference, tried to reset with the little black plug you get still no difference, when the fuse is out the indicators do not work have left fuse out, but what i found strange was that when i locked it the indicators flashed as per normal? have pushed and wiggleled all fuses and relays in fuse box had the engine running and heater on while i did all this, any help or advice and at what cost your actions for me to do thank you all once again.

sounds like ur alarma being triggered off when that fuse is in or possibly wiring issue. am no expert on this but i had a clifford installed on mine and the chap had to call into clifford coz the wirin loom for the altezza was different to the is 200. take it back to the chap that fitted it seems likes its being falsly triggered - either sonic sensors or a wiring issue.
