davis36 Posted September 27, 2008 Posted September 27, 2008 Hey guys need some help...need to know how to reset ECM (ELECTRONIC CONTROL MODULE) on a 98' Lexus ES300. Appreciate any help. THANKS!
1990LS400 Posted September 27, 2008 Posted September 27, 2008 My understanding is that doing a proper restore of the main ECU requires the hand held scan tool (Lexus Diagnostic Test Kit, Part number 01001270) and the appropriate program card for a 98 ES300 (6.0a Diagnostic Software Card, Part number 01001895-005). I checked a few years ago and found that the total cost of these tools was over $1,000. I do not know if there are less expensive alternatives. Also, questions about the ES should be posted in the ES forum instead of the LS forum.

THANKS! disconnect the negative cable to your battery for about 10 minutes. This will reset your ECU to the default factory settings. All "learned" attributes will be lost as well as your radio presets and memory seat positions. steviej
