Got my daughters 2.2 camry 96 repaired and ready for blue slip.
Out of the blue I noticed that the security light was blinking like an engine check light definatley 3 blinks then a pause and 7 blinks.
Searched for engine codes but they start at 100.

 

Might ask at the Toyotanation website.

If dealer or factor installed the unit would be a RS-3000 system. An internet search will turn up manuals but none have anything about this code.
