Lights flash, keypad works and the remote works but no siren. Anyone know how to solve this? Sometimes if the vehicle's battery is run flat the alarm ECU and siren can go out of sync. as the siren has its own power supply. This leads to the sympton you describe of no sound at all, although everything else works fine. The siren is unlikely to have been disconnected. The problem can be easily fixed by discharging the siren's internal battery. To do this: - Locate the alarm ECU (you should be able to hear the relays clicking if you trigger it with no siren!) - Remove the alarm ECU from its security case (this requires the use of anti-tamper bits). - Remove the white 4-pole connector from the alarm unit (this is essential - do not attempt to procede without removing this connector, otherwise the Red wire in pin 1 will be 12v permanent live) - At the 4-pole connector running to the siren (NOT THE ECU CONNECTOR) short accross the Red wire in Pin 1 and the Black wire in pin 3 for several seconds using a short length of wire. - Reconnect the 4-pole connector to the alarm ECU The siren should now operate normally, although will take several hours to fully re-charge the back-up battery. Best of luck SS |
This souds like it coud be the problem as it as been in a bodyshop and also had the battery replaced, but for the life of me I cant find the ECU. The only place I can think to look now is behind the centre console but its to dark to see now so I will have another go tomorrow. Indicators dont help whilst tracing the clicking relays, so idea remove the inicator fuse.

The alarm enclosure is gold in colour and about 5" x 5" and 1" deep. You will need anti-tamper torx bits to remove the unit. Best of luck, SS |
SS you are genious spent the last hour fiddling around trying to get the ECU in and out but it was well worth it, alarm system now fully working :D
