Is200 security light flashing.

Postby Edwardo1988 » Thu May 11, 2017 9:54 pm

Hi all so have a 01 is200 sport.
Went to try to start it last night, engine turning over but not firing. Noticed red security light on dash was continuously flashing and would not go out when key was inserted. Have tried disconnecting battery for few hours and reconnected but same problem again.
Anyone ever see this issue before or has anyone any ideas what could be causing it?. I have had the key checked at a locksmiths today and they say key is fine and that there is a signal being sent out so surely must be an issue with transponder or ecu?.
Thanks.

Not sure on this but I presume you havent got a spare key that you can try? Have you looked inside the box where the ECU lives to seen any signs of damage or water etc?
