riwyle Posted February 6, 2015 Posted February 6, 2015 2006 RX400h Check engine light came on. Read codes $7EA and $7E8. I have never seen these codes or this code format before and cannot find their meaning.. I was able to clear them with my scan tool. Have not again appeared. My scan tool instruction book mentions numbers of similar format, $01 through $09 defining a mode for diagnostic requests, with 7 being a particular data byte 7, and response data being at 7 plus 64 (thus 71 for this mode). Can anyone with OBDII knowlege tell me what these codes mean and/or what is meant by Mode? Help appreciated. RI Wyle
