Two months ago my starter motor didn’t work so I used push start to start my car after several attempts suddenly abs,tc,hill decent warning lights came on.I fixed the starter motor but lights keep illuminating I checked everything
Abs sensors using multimeter
And abs sensor voltage by turning wheel they all ok
Relucter rings are in good condition
This is a real pain
Can someone help please
I have freelander 2000
2.0 diesel

You say you checked everything, but no mention of the ABS pump/modulator, gearbox switches, ABS ECU, brake/throttle switches, fuses, wiring looms etc.

You need to take the car to a garage to get the diagnostics read for the ABS system to find out what's wrong.

The only thing I can think of that might be related to the other issues you had are electrical spikes caused by the failing starter motor. They can kill electrical components - such as the electronics in the ABS ECU and modulator. You need the codes read to find out what is wrong.

Can u please tell me more about electric spikes thing

Not really as I'm not an electrician.

But surges of electrical current through the car's systems can damage (burn) the car's electronic components and corrupt the computers.

A low battery can cause an erroneous code to be generated, which can put the lights on. You need to get the codes read, and cleared, to see if the fault is genuine.

today i went to a mechanic and scanned the car and remove all fault codes then warning lights switched off
But after driving 200m lights came back

I did
It was saying that left fronts sensor output is too low
Is that mean I need to replace the sensor?
My mechanic knows nothing about English vehicles

I would imagine that is the sensor then - but there may be an issue with the wiring to it.

You could try swapping the front sensors over and see if the fault moves to the other wheel before buying any parts. However, only try that if you can get the sensors out without to much difficulty. I can remove the sensors on my car OK, but they can rust into the hub and become a right PITA to change. Obviously, you don't want to damage anything and end up having to buy 2 sensors.

As you suggested I swaped the sensors and scanned again still it shows that front left sensors electrical failure massege.what should I do?

You'll probably need someone with a bit more experience to give you a more reliable answer, but it if the code didn't change then the sensor is OK - so it must either be the wiring between the ABS ECU and the sensor or the ring on the drive shaft - actually, I'd think it more likely the ring.

I believe both wires for the sensor go to the ABS ECU which is located under the drivers seat (I believe you have a Rover L Series Freelander). You can download the Rave Workshop Manual which has a full description of how the ABS system works and full electrical circuit diagrams. There's info on downloading it here...

https://www.landyzone.co.uk/land-rover/rave-disk-maintenance-manual.260227/

You can maybe check the continuity of the wiring between the ABS ECU plug and the sensor connector.

I believe the reluctor rings usually split due to a build up of rust underneath them - not sure if this is likely in Sri Lanka. You may be able to check them through the sensor opening by feel/sight rather than having to take the whole drive shaft off - not sure, maybe someone can offer help.

Good luck.
