Might need to read owners manual and see if these two circuits are on the same fuse, then see what you need to do about resetting alarm. Then report back what you came up

Often when the battery is disconnected or replaced the computer will lose it's learned idle settings. You could try letting the engine idle in park until the engine temperature comes up to normal and leave it like that for a few minutes, then put the Air con on and let it idle again for a few minutes, then switch the air con off and put it into drive. If it does not stall, let it idle in drive for 2 minutes or so, and then do the same with the Air con on. This should relearn the base idle settings and stop it from stalling on you. Before you carry out this procedure you should make sure that when you replaced the battery you didn't remove any other plugs or knocked anything that may be causing the fault. If you try this procedure and it still stall when you select drive, you will need to get a Mechanic to check the vehicle over.

Hope this helps,
Mark.

Have your battery checked to make sure it does not have a bad cell, have your alternator checked to make sure it is putting out a full charge to your battery. Sometimes the ASC light is activated wen there is an engine issue that does not have it's own code.You may also wish to have your parking lamps checked to make sure your lamp connections do not have worn wire covers that may be grounding out.

You can also take a paper clip (can mess things up, but I use it) And have it touch the 7th & 19th pin inside the service port.

more than likely is being caused by a faulty level sensor but first check the connection and fluid level when engine is cold as fluid level will rise when engine warms up
