I had a problem with my Toyota Camry 2000LE tail lights (license plate lights and two second lights) but I found three wires that supply the voltage to these lights disconnected then I fixed the problem and all the tail lights woking properly now but still I can see the tail lights fault indicatior in the dashboard after fixing the problem even after starting the engine how can i reset this tail lights fault indicator in the dashboard, my friend brought his scanner that he used to use with his car HONDA Civic but we could't find any fault code in the scanner how can I solve this problem?
Also I can see the check engine light and the oil light on in the dashboard but before starting the engine and once I start the engine these litghts disappear how can I reset these lights that apprear before starting the engine. Thank you in advance for your help.

Best regards
