Reset warning light on a2000 jaguar s-type
You can reset the engine warning light by taking the earth lead off the battery and connecting it to the positive lead, then switch on the ignition,. Reconnect the earth lead to the battery and the light will have been reset. What you are doing is discharging the diagnostic chip to earth, which is exactly what the jaguar main dealer equipment does.This works on all cars.
PLEASE NOTE, make sure you disconnect the earth lead from the battery .
Just jumping the battery leads together will not cure the problem, as JPTcat suggests. However if you read my post it says that you have to turn the ignition on whilst the battery leads are together this completes the circuit to earth enabling the capacitors holding the chip voltage to be discharged thus clearing the chip memory. This has worked on my own S type, my wifes huyundia Amica, my sons Citroen Saxo and many of our friends cars. I am an electronics engineer of some 30 years experience and i gaurantee this will work.
I tried this exactly as described and everything reset back to zero(even the clock) EXCEPT the engine light. I am also an electrical engineer and the way this was explained makes complete sense but it DOES NOT reset the engine light.

On all Jaguars, by disconnecting and jumping the battery terminals does not work, the memory still holds the code.
The only way to reset the lights is with a OBDII scanner, you can pick them up for as little as $30.00. But there is a reason why the light is on, so if you do clear it without fixing the problem it will come back on. Also if you are trying to clear it just to get a smog, that won't work either, once the light has been reset, the vehicle must complete a series of readiness test that can take upto a hundred miles to compelte before you can smog the car.
Good luck
Obd scanner is built in it only tells you the code

Just to let you know, my check engine light went on and I searched online for a cause since I didn't believe the codes at the auto store. Turns out the codes telling me vacuum leak were correct but it is a simple fix - new gas cap. I worked. Now I am buying an OBDII tester to be able to turn off the light when necessary to reset.
