Warning light comes on and stalls put in to neutrel starts ok .brake then light comes on stalls start goes in to limp mode ive got 1997 xj6 4l sov lwb thanks andy .turn off start up light gone out ok

The only thing these components have in common is the ground wires. There are many grounds on a vehicle. But the main three are the battery to body, battery to engine and engine to body. These are fairly large wires/cables. They should be checked with an ohm meter. I replace or repair any wires that have more than 5.0 ohms of resistance.

washer jets could be blocked try a drawing pin to clean them. As for limp mode you should have engine management light on if you do use obd scanner for fault code.

i had a problem with all my lights coming on in my 2006 explore took it to dealer to find out that the battery was dying replaced it and they went away

It sounds like it could be an ignition problem. Them can go out anytime with out warning.

check the brake fluid level, if its low, it may be time to check the brakes for wear. As your brakes are used up, the fluid goes down and turns the light on.

WHEN THE ENGINE MANAGEMENT LIGHT COMES ON YOUR MANUAL NORMALLY SAYS TAKE IT TO THE DEALER, AND THE STALLING IS PROBABLY A LIMP HOME MODE

well here's a start towards ur problem, due to the auto circuits u have an open return to the negative side of the battery. Have you done anything with the vehicle's systems before this started? the reason fo the strange lighting is that a positive voltage is being applied to what normally would be return side. You will need to get an electrical diagram if possible to pin point area if as previously asked didn't occur.

look at your wheel speed sensors in the back ( this is where I would start)

This great car does not have speed limiter, as you said the limiter is starting because the ECU detects a problem and put the car in limp mode, starting the Rev limiter.

The only way to know the problem is by connecting the car ECU to a code reader, and interpreting codes.

If the car goes in limp mode when you press the brake pedal can be a brakes related problem or even a contact on the brake light wirings, check if the lights are are working.

Ask your mechanic to scan the ECU, this will tell you what the problem is.

Code 24 is a vehicle speed signal sensor fault, the sensor most likely does not provide a useable signal until about 25 MPH, when the computer doesn't see any signal after that speed it turns on the light. Make sense?
