Call a Caddy Dealer -they should know how.

Try removing the fuse or relay for the antitheft system.

So does mine, the blower fan will just run till the temperature sensor reaches the set point, usually a few minutes. If it does not stop within 10 minutes you need to have the temperature sensor checked out.

1. Have your battery checked - Load Test 2. Check cable connections at Battery and at Starter solenoid, must be clean and tight. 3. Have the starter motor checked

it will come on if oil is worn out and not making enough pressure to lubricate motor

Fuse, motor, switch, bad wire?

That code should be left rear(Drivers side rear) wheel speed sensor short to ground, Check to see if wiring has worn thru and is contacting metal some place. GM had problems with water getting into wiring harnesses in rear causing shorts.

It is located on the fuel rail in the engine compartment, fuel rails are on top of the lower intake.

Have someone push down on the hood, as you try one last time to release it, from inside the cabin Once open--clean & lube the round part with the spring around it, on the hood & all moving parts of the lower hood latch, where there are levers & pins holding them

check the ground wire on the blower motor ... that usually stops the motor when everything else is ok.

If you mean ECT (Engine coolant temperature) sensor, yes it can. The ECT is responsible for turning on & off the radiator cooling fan. However an ETC (Electronic traction control) sensor typically wouldn't cause the engine to overheat. However if there is a code in the engine computer it can turn off the traction control. So if the ETC is turning off it may be a result rather than a cause. You'll need to check for codes in the engine computer & if there is one for the temperature sensor you most likely will need to replace it but you'll also need to check the coolant level. If it is low you obviously have a leak. FOOT NOTE: This engine is well know for its HEAD GASKETS leaking coolant. If you are having persistent overheating conditions & can't seem to locate the cause ie; water pump, radiator, hose ect. you most likely will need to have the head gaskets replaced... & that isn't cheap. Hope this helps. FarrouT!
