brakes got done but now my abs light is on brakes work fine and don lock up so what wrong with it

What has been done to them,

What Model Car

Could be

Dirty Sensor ring, Clean Sensor rings,
And the Pick up as they are magnets any metal meterial will stick to them, and give false readings,

its a 93 ed fairmont pads changed and were is the sensers and stuff

The sensors are behind the Brake Rotor,

The main ring is fitted to the brake rotor, the sensor is bolted to the stub axel,

Fault Codes

The 2 digit Fault Codes are read as flashes of the ABS Warning Lamp.
Example: Fault code 17 = One flash followed by a pause, followed by seven flashes.


Codes may also be extracted from the Diagnostic Connector.
Connect a Voltmeter or LED test lamp to the Diagnostic Connector ABS/STO terminal.

Fault Code Erasure
1. Connect a jumper wire between the Diagnostic Connector terminal ABS STI and Ground.
2. Switch ignition ON.
3. After 10 seconds approx. the ABS Warning Lamp will begin to flash codes.
4. As the fault codes are being outputted to the ABS warning lamp, remove the jumper wire.
5. After a minimum of 5 seconds, switch the ignition to OFF.
6. Carry out Fault Code Extraction to ensure correct erasure.
7. The ECM should flash "System Pass" code. (Code 11)

Fault Code Extraction



When the ignition is switched on, the ABS ECM performs a self test.
The absence of a correct Ground strap will cause permanent failure of the ECM.
Ensure that the battery Ground strap is fitted correctly before switching the ignition to ON.



1. Connect a jumper wire between the Diagnostic Connector terminal ABS STI and Ground.
2. Switch ignition ON.
3. After approximately 10 seconds the ABS Warning Lamp will begin to flash codes as follows:
The ECM module identification code = 9 flashes (Code 90)
Any current fault codes. (These will be repeated twice)
Separator code - 1 flash which will separate current fault codes from previous fault codes.
Any previous fault codes from fault code history.

(history fault codes erase after 50 ignition starts - Memory roll over = 50)

Hope this help a bit

Scotty2611

hmm yer thanks for that with all the info i might b better letting a auo elec look at it cheers

It really is not that hard mate,

Would pay to spend some time and have a go

ok kool i dont have the gear but if im up ur way and i give ya some notice and cash could ya do it and show me at the same time

Did you get ABS compatible pads? They are different I am led to believe.

duno was done just befor i bought the car

There is no difference in the brake pads, just the rotors

Scotty

Ok cool, I know the Mitsi Magna/Diamante ones are different, was assuming these would be too.

Cheers Scotty!! You’re a legend mate. Can see you put time into this so thank you.
