Inertia Switch

[ducmed]

Hi there,

I am working with a 2000 Land Rover Discovery II with 118k miles. I have been having issues with.. what I am thinking is my inertia switch. The vehicle will turn over and everything has power. It just will not start. It doesnt even want to start after attempting to reset the inertia switch. I am just wondering if anyone has had this problem before or if they know if just bypassing the inertia switch is a possibility for a temporary solution.
Thanks

Crankshaft Position Sensor. (CKP) Oh yes. That is it. Check out my earlier thread and good luck...

I don't know how to post a link to my thread but it sure worked out for me.

I forgot to mention that the four ways are constantly on ( I removed the fuse to prevent the draining of the battery) and when I attempt to start the truck the horn honks and when I turn the key to off the horn honks. Would this still be the Crankshaft Position Sensor! Please say yes! This would make my life a thousand times easier.

Security system, is your red light on the dash flickering?

[ducmed]

I have never seen the light flicker on the dash. My truck has an aftermarket alarm with remote start installed. I never got the original key or key fob with it. I also have never been able to use the power locks. The lock switch on the dash does not work. I can here it clicking, like a relay somewherem but it doesnt actually lock the doors.

I went through the exact scenario on my wife's 1999 Disco II...

Regarding the single horn honk and subsequent 4-Way flashing, that is indeed caused by the IFS being triggered. Hers did the same thing. I thought my IFS switch was bad. I bought an in-line spade fuse holder and "Jumpered" the IFS. What I discovered was, there was nothing wrong with my IFS. When I pushed the reset button on top of IFS the 4-ways stopped flashing and no more horn honk.

I installed the new CKP (Actually my mechanic Brian did for $65.00 labor) and it cured all of the starting problems. Disco fired up as new!

It was hard for me to believe that such an insignificant little part could cause such a calamity but........ it did.

Good luck on yours.

I just went to Autozone and ordered the Crankshaft position sensor today. I am really hoping this works, I wanted to take the truck on my small vacation this weekend. Any other helpful hints regarding this problem... I have read quite a bit about the CkPS and it does sound a lot like the symptoms I have been having... i.e. dying randomly and being able to start it randomly. Just the last time it died, it wouldn't start back up at all. Fingers are crossed that this works!!!!!! I miss my Land Rover

Ducmed,

I think you will be happily surprised. If you are doing it yourself you need a 7mm and an 8mm box wrench, long as possible...

Good luck.

UPDATE:

I replaced the Crankshaft position sensor. The old one I pulled out, the metal part that is inserted inside was bent. I am also trying to get the serpentine belt replaced with no luck. The belt just seems way to small. I do have the ACE and I got the belt for ACE. After replacing the CKPS I tried to start and still nothing. I tried with my old inertia switch and with just crossing the wires for that switch. I just read my codes...

P1884 CAN message WFPDK (DKI) Invalid (FFH)

P0560 Generic System Voltage

P1536 Land Rover - Air Conditioning Compressor power stage fault drive cycle A:Signal Missing

P1668 Land Rover - Anti Theft Alarm Serial Link fault drive cycle A: Signal out of range above maximum

I'm bumping this old thread in hopes to fix my 02 Disco II. I had these exact same codes & problem, bought it from a friend this way. CKPS & inertia switch have been replaced along with fuel pump. I then suspected the battery, had it tested (good) and fully charged, cleared the codes, still nothing. Checked the codes again, now I'm down to only P0560 & P1536 with no start. I know we can't be the only people in the world that have had this problem. I pm'd ducmed a couple weeks ago but he has not responded. Someone PLEASE help!
Fuel, Spark, Air...
I know it's not getting spark because not even a hint of crank after spraying starter fluid into the throttle body.

somebody help me out here..
disco mike?

The P1884 has 8 different possibilities. needs to be read by the dealer for accuracy.

the p1668 will most likely by a dealer thing also (security system issue).

thats all i got. good luck

P1536 Land Rover - Air Conditioning Compressor power stage fault drive cycle A:Signal Missing


Any help with these 2 codes is appreciated.
