Is your remote being triggered by mistake? If not it has something to do with the receiver circuit for those two electronic switches.

you have a problem with the ABS system. the traction control is disabled when the ABS malfunctions. most common problem is a bad speed sensor.

Of course, as you know, the air ride suspension has a problem. Does the vehicle sag on one or more corners if it sits for a day or so. If so, you may have an air leak or a defective leveling sensor. Also check the fuse for the system to make sure it is not blown.

Your computer has detected a problem in your air ride suspension. If is most likely either a height sensor but could be the compressor or air bags.

Does the system drain down overnight? That could mean a valve or a small tear in the air bag or even an air line. If the compressor brings it back up when you start the vehicle that would tell you the compressor is good, or at least not the problem.

Hello,

this is more or less a weak battery. This is common when the battery of the vehicle is weak.... I think the battery is weak such that it cannot start the vehicle.

Borrow a batter from a neighbor, family or friend. See if the car would start.

Please let me have a feedback.

Bye for now.

The most common overheating problem with the Northstar engine is a blocked purge line. It's job is to purge air out of the cooling system.
There is a small diameter hose coming from near the top of the coolant tank,this is the purge line.
With the engine idling,pull the purge line from the tank,if there is no coolant flow from this small hose,it is blocked and this will cause overheating.If the hose is clear, check for blockage at the nipple on the tank.

Your passkey security system is activated. The key has a transponder chip in it, if the ignition doesnt read that signal correctly, your anti theft will kick in to stop a potential car theif. Try turning the key forward like you are trying to start it. 2 clicks forward, for 10 minutes. Then turn it back and forward again and try to start. This may reset your system. If not, Its probably DEALERSHIP time.

it mean that one of the electronic load leveling sensor is not reading. that sensor tells the air pump to fill up that air shock or air bag. the sensors maybe reasonable price wise but if the sensor is reading that an air shock is not holding air pressure and an air shock is not cheap.

could very well be starter, battery should read 12.45 or so,,,does the car try and turn over or just nothing?Did you try jump starting it? when you turn key to on position is check engine lite on?

Look in your trunk. Pull down or away the carpeted lining which covers the rear seat back wall. You will find a fuse box panel on the left passenger side when you do this.

The only effected way is to replace the oil pan.Oil pans are available at the wreckers all day long. This is aluminum right? Whats the problem with the pan.
