Radio keeps turning on/off, clears out clock,service engine soon
The radio on my car keeps turning on and off, and sometimes, will clear out the time on the car clock. and after a few days, the 'service engine soon' lit up. please help.
the same symptoms happened a month ago. i had it looked at and realized the water pump had to be replaced. i had that fixed and replaced the hosts too. and now the symptoms are happening again. what could be wrong?

have you tried to pull the computer fuse out for a couple of minutes then re-install to see if it cleared. the other thing to try is to disconnect the battery for 5 minutes then re-connect this should clear but keep in mind if you have an anti-theft radio in the car you will need a code to reset the radio for it to work.
I believe you mean resetting the Code. You can go to Autozone, Advance, or Oreilys and then can reset this for you, free. Sometimes you can just disconnect the NEG post of your battery and the computer will clear. But most people do not like resetting their clock or radio when you do this.
it may have nothing to do with it or it might, you will have to let them scan it and see what code pops up and then go from there. maybe something got lefy off or got knocked off during the tune-up.hope this helps.
A scan tool is the only way to reset the SES light. there may be a resean the light is on make sure to record all codes. I would take it back to the tech that serviced the van possibly something was left loose.
If the engine is running fine and you disconnected the battery recently then don't worry about it. To clear the check engine light and the code�s you can do one of two thing�s. One pull the negative battery post off the battery for 30 second�s. This clears the computer codes and the light. However it also clears your radio presets and clock.
Another way is to pull the fuse labeled �Fuel Pump�. This fuse is in a box under the hood behind the battery (See photo to the left), Should be the only yellow 20AMP fuse in there. This fuse also disconnects power to the PCM "computer" as well � Kind of a secret to the general public� Just leave this fuse out for 30seconds or so.
Then replace. This will keep your clock and radio presets.
The engine might be a little hard to start or die the first time since the computer has to relearn everything again
Note the radio anti-theft code & station settings;
BE SURE YOU KNOW HOW TO RESET THE ALARM;
Be willing to reset the clock;
clear the MIL code, then:
remove the negative battery cable for one minute during which time, to clear any capacitor stored elctricity, then re-attach the battery cable and reset the alarm, radio settings and clock.
If that does not solve the problem, replace the fuel injector control module.
You need to have the vehicle scanned or pull the code out with a code reader,and address/fix the code.If you do not repair the problem,you can clear the code,but the service engine light will come right back on.To clear the code,you can disconnect the negative terminal on the battery for at least 20 minutes,then reconnect the battery,but the car is going to be hard to get to idle,because sometimes the computer has to relearn how to idle the engine without stalling.Good luck.
