We just bought a 2006, used IS-250. It has 30k miles and is in beautiful shape. It came with "
Auto Mate" which is an OEM add-on for additional security. We're not sure Auto Mate is causing the issue below, or if it is the standard security system.
Issue: With the engine running, I push the ignition switch to turn off the engine. Here is the sequence/duration of horn beeps:
-one short
-pause
-two short
-pause
-one extended (about 2-3 seconds)
This must be an error/problem, since I see no way anyone would program a system to do that after a normal engine stop. I've read the small "Auto Mate" manual and it does not mention any beeping after ignition stop. I also looked through the regular Lexus manual and have found nothing related to this.
Please help. Any clues will go towards solving this issue.
Thank you.
