Adjusting info display after battery disconnect

rds means radio data system. most modern stereos will need a security code when battery disconnected or drained so much there wasn't sufficient voltage to hold memory.if its a vw stereo and u ent got the code a vw main dealer should help u out

as long as the oil change has been done turn ignition on dont start engine just so all lights on and hold down the accelerator and brake down at the same time for 3 to 5 seconds or when the oil info goes out. its reset then.

Water got into the electronics, where is any ones guess, let it dry out for a week and see if the issues clear.

I need more info on this, but if your given an error coad from something your on the right track to fixing it?
What's displaying the error? Any information on what caused the problem? Year? Model No? Size?
Disconnect the battery and have another go.

1st mistake: you didn't get an H1 lol
2: Most modern cars have an anti-theft device installed in the radio. That means if the battery becomes disconnected for ANY reason your radio won't work without a special code being entered. Your local Hummer dealership should be able to provide you with a code. The code is NOT the same for every vehicle.

Hello Eric,

No such thing as "no reason" I am afraid...!

Possible causes are: things being forced under the seats, esp when the seats are moved. Someone adjusting the drivers, or passenger seat to it maximum limit (either way). There are often wires under the seats/in the seat belt stalks that can get pulled causing the AB light to come on. You can check to make sure any under seat wires have not been disconnected, with the ignition OFF.

If nothing obvious get someone to read the codes out from the control unit, high resistance is a common problem. However, and this is VERY important, you SHOULD NOT attempt and work on any SRS/AB system unless you are qualified to do so and/or have the battery disconnected. EVEN WITH the battery disconnected, if you use a multimeter on ohms setting, you can trigger the SRS/AB and they are deployed with HUGE force, enough to kill or cause serious injury. Please DO NOT risk working on this system unless you are trained to do so.

This problem generally occurs when the battery has been disconnected. What you will have to do is go into your owner's manual and call Honda USA for the program code. What you will need at the time of the call is vehicle's registration. The information you seek is in the owner's manual and don't forget to write the code down, just in case.

If you really plan on chasing this one down as a DIY project, you will need electrical diagrams from your car. You can find these and a whole lot of other information here:

Even if you don't care to do your own maintenance, you can get an idea of the potential cost of a repair by looking into the complexity of it before committing to a sky-high repair bill.
We have a Haynes in each of three vehicles and they have saved us time and money.

Did you take out the battery or disconnect it for whatever reason? if yes you will need to call your dealer and request for the radio code.

Disconnect the battery before starting the job! Your power cable from the alternator will be disconnected and could potentially ground out if your battery is not disconnected!
