Lexus Troubleshooting Questions? Ask a Lexus Expert
The starter does not crank, I have full power however the starter doesnt crank. Also, I can't lock and unlock the car with the remote.
I gave direct current to the purple starter relay with my power probe. The car turns over fast so I know the battery is good. It has a push start ignition.
Just one key.
The light stays green. The engine does not crank over when I push the start button.
This means that either the key immobilizer code is not communicating with the immobilizer ECU or the communication line between the immobilizer ECU and the engine control computer is malfunctioning. The weakest link is normally a bad key fob. The only way to know for certain is to use a Lexus scan tool that will communicate with both of these ECUs on the high-speed can network.
The car was running yesturday without any problems, I changed the battery because a light was on, is there any way to manually program the key?
Yesturday I jumped the car with no problems, for the most part im stuck.
The battery has gone dead before in the recent days and each time it has started with a booster with no problems, only until this morning did the same issue occur and this time I couldn't get the car to do anything.
I definitely beleive that the security system may be shutting the car down. The security light has been flashing, I've tried everything so far.
