2006 Toyota Corolla does not display engine light
Can somebody please help, my Toyota Corolla does
not display engine light when turned on, it doesn’t
have security light and doesn’t have spark. How
can I solve this problem?
Unplug a sensor that uses the 5 volt supply like the tps or map... if u cant find 5 volts your computer is offline... check all the computer fuses..... if all computer fuses are good then get a diagram for the car and unplug every possible sensor that uses your 5 volt supply line one at a time and see if you get it back leaving them unplugged...
You should first replace the bulb to see if its blown but it can mean theres no communication with the way, check all fuses
Sorry i meant no communication with the ecu
