What is the radio code for a 2002 Hyundai Accent. The battery was disconnected! its a hyundai radio (factory)

P1586 HYUNDAI - MT/AT Encoding Signal Malfunction https://www.autocodes.com/p1586_hyundai.html

What your car is shouting at you is that there is a low power problem. This may be simply a battery cable or a corroded connection but the systems are not able to get the power they need. I would take the vehicle to a AutoZone (or competitor) as they have free diagnostics for the battery, alternator and etc. They can also read the codes in the OBC module.

If it is saying code 2, thats not a code to input anything. Its a error code for a hardware malfunction.

you'll have to go to the dealer

if you sweet talk the service writer you might get the code for free...make sure you tell them how much you love the car and the factory radio and would hate to have to buy an aftermarket radio

However, more often than not you'll have to pay for service and at $90/hour it might just be cheaper to get an aftermarket radio

if you pull out the radio from the dash, it will either have a serial number on it, or if your lucky will have the code written on the radio.
if you just have the serial number, then let me know and i will supply your code if you provide me the serial number.

if you follow the positive+++ lead from battery it will lead you to starter located at back of engine nearest the bulhead make sure you remove/disconnect the battery earth lead 1ST b4 you commence work also if radio is code type ensure you have code for rest after work done out of curiosity?? what are you needing starter location for ? we may be able to help you with problem ? b4 you start or renew starter unnecessarily ? just a thought ??

ask the dealer
