No, you can't clear codes on any vehicle by disconnecting the battery. Thet are stored in the ECM and are still there when you re-connect the battery.
You can if it's not newer then a 1998 model. If it's newer then a 98 then you will need a engine scanner to do that.
Try disconnecting the + battery cable for 5 minutes.
Disconnect the positive battery cable for a couple of minutes.
Remove negative battery cable. Turn on headlights. Wait 15 minutes. Turn off headlights. Replace negative battery cable. Better, go to Autozone, ask them to plug in their OBDII analyzer and hit "Clear". that way you do not clear the corrections the computer has added to the system and will have to relearn if you remove the battery cable. just remove the negative battery cable,wait 5 min,and put it back on,, computer will reprogram all by itself. Pre 1995 vehicles disconnect battery for 10 Minutes minimum Whats with turning on headlights with the battery cable removed? They will not work anyway
NO.
On the vast majrity of 1992 OBD1 vehicles, removing the positive battery cable for 15 minutes will clear all codes.
Remove the negative battery cable for 6 minutes and then replace.
Is there not a reset button on the back? If not, then take out the battery, and the memory. THen out them back in after taking them out for 20 seconds.
In most cases disconecting the Neg. Battery cable will clear a code like this, as long as the gas cap is in good condition.
You clear code 42 just as you clear any other code. Disconnect the battery cable from the battery for 30 seconds, then reconnect. (It's good practice to disconnect the battery cable whenever disconnecting or changing any electrical components.) Afterwards, check the "check engine light" to see if the code 42 is cleared. This answer applies only to '95 and older models (OBD-1).
where can i attach the negative of my cable to jumpstart my battery for 1997 Montana van. Attach the negative cable to any bare metal within the engine itself, be sure to keep the cable clear of any belts or moving parts. There is a bolt in the middle of the engine that I used last week to perform the task.
Disconnect + cable on your battery , go inside vehicle , sit in drivers seat , apply pressure to brake pedal for 5 seconds as if you were making a stop . Reconnect Battery , should be clear .
