What year is your caddy ? Given the amount of electronics on these vehicles it could be a lot of thing's ! Are there any lights lit on the instrument cluster ? check engine , security etc.. The charging system on your caddy is computer controlled an if it is showing a service battery charging system warning message there are DTC'S stored . This is one your going to need to take to a dealer , do you have Tech 2 scan tool to hook-up to the vehicle ! It could have an ignition switch problem , power mode miss match ! All the modules on this vehicle communicate on a data bus, serial data communication . class 2 ,C.A.N -controller area network ! When you turn that key to start the vehicle ,the ignition switch sends a discrete voltage input to the BCM -body control module ,which in turn energizes relays that powers up systems on the vehicle ! So do yourself a favor before you make it worst !

SOURCE: cadillac escalade ext will not start dic message

A battery can read 12 volts yet be weak in cold cranking amps, try a jumpstart and if that works have your battery load tested. Im betting your gonna find the battery fails the load test, meaning it needs to be replaced..

check your battery make sure it is able to take a charge. ,if the amps are good check your connection, from altenantor to battery. check voltage drops, battery drains. Your problem most likley seems to be
your battery. Your starter might also be draining your battery. You ll find the problem keep looking.

Radio shut off while driving. All lights on radio display not showing up. Also, when using the turn signals, I don't hear them anymore, and when key in ignition, the chime doesn't sound.


Make sure battery and charging system are working properly. If charging system is not effectively charging the battery and the battery runs low on charge, the vehicle will start shutting down different electrical units/modules in order to keep the vehicle running

03 escalade won't start or turn over


Do you have power?
battery might be drained cause your alternator is not charging anymore, 2003, seems about time for a new alternator, those vehicles consume lots of power cause pretty much everything is electric, lots of motors and servos, so they depend a lot on a good power source from the battery. If alternator doesnt charge it, no power...

have power system checked.

Good luck.

2006 cadillac says " service


check out this link. It will help you understand the system. There is a section on this link called "quick fix". It describes a 10 minute trick. Perform this trick 3 times in a row without trying to start the car in between. Turning the key back to the off position after each ten minute cycle. This is a complete passkey reset. After the 3 rd time, turn back the key and then turn it forward and try to start it. The whole process will take around a half hour. If this doesn't work, you'll need to take it to a dealer. Good luck. http://vatspasslockpasskeysecurityhelp.yolasite.com/

My engine won"t turn over on my 97 cadillac


It could be the starter. It could be a bad battery cable connection. Have you tried jump starting the engine. If it starts, then most likely it's to do with the battery or charging system.

Escape doesn't start, battery is ok, 12.6v. starter does turn over, but vehicle doesn't start, what could i look for?


Put a charger on the battery overnight first, yours is a little low. Put the charger on a trickle charge, about 2 amps. A fully charged battery should be at least 13.5 up to 1.2v. It could be that there is enough power to turn it over but not provide power for spark.
If this works, then you need to get your charging system looked at to see why it's not keeping the battery fully charged. The battery may be weak which will show up in a "load test". Your alternator may be starting to wear out or the belt could be stretching and starting to slip or you may have something staying on, when the truck is turned off, that is drawing power. It could also be that the starter is drawing more power because it is starting to wear as well.
Try these and see how it goes. Hope this helps.

When i turn the key the escape wont start it just makes a clicking noise?


That noise is probably the starter solenoid rattling because the battery charge is low. Start out with a jump or make sure the battery is fully charged up.

Car won't start, jump starts ok, battery showing charge, can't turn it over from ignition


If the car jump starts ok then I would suspect that the battery is old or will not take a charge or loose connection at the battery. Replace the battery with the recommended battery (don't get the cheapest replacement). Cadillac's have loads of electrical demands and/also when the car is not running.
