Have Toyota Questions? Ask a Mechanic for Answers ASAP
This is normal operation so radio is not able to completely drain the battery leaving you stranded. Let me know if you have more questions or if there is anything else I can do to help. Thanks.
This is considered normal operation. After a preset time the vehicle shuts off power to the radio if vehicle is not running to save battery life. If radio works fine when starting vehicle then everything is working like it should. Let me know if you have more questions, thanks.
Sorry about misunderstanding, give me a couple minutes to pull up wire diagrams. Thanks.
The 15 amp Dome fuse under hood supplies radio battery power and 15 amp ACC fuse left of dash supplies it ignition voltage. Check to see if both fuses are good, if so check to see if both fuses have power. If both are good then your radio has probably failed but to know for sure you will need to verify blue/yellow wire and gray wires have power with key in on position then verify brown wire has good ground. If all 3 are good but radio does not power on then it needs to be replaced. Let me know if you have more questions or if there is anything else I can do to help. Thanks.
