well abs lights ussaly come on when a wheel sensor detects a bad caliper Check all your brakes and check the wheel sensors *aka the timing sensor * its attached to the hubs one of them may have gone bad

thanks for your answer.but not the abs light is on all of this is on like EPC,Steering wheel,ABS,PARK brake,alos AC is not working,ESP is not working,auto hold is not working...one of the local mechanic said u must change your abs but same and sair change abs plug and again same ,when i want to connect to computer and click ok on abs it gave me error.what can i do ???


hmm well i would try and have those codes read. The car will give you the codes so grab those and post them here. in the mean time if you have the radio lock code remove your battery cable for 15-30 minutes after geting the codes scanned. also look around the fuse box and any wireing harnesses under the dash for damage this is sounding more like some one broke something or unplugged something


thanks for your answer bro but i want tell you some thing my car has not any problem before but some times all of the lights were on and made a sound like warning sound when i check abs i saw one of the terminals was break but i saw someone before me connected it by small wire,and then i want to change this abs pump i bought from ebay when i install just abs light was on i went to check by computer but it did not connect i exchanged 3-4 times with the oldest one after that all the warning lights were on but also same didn't connect.one of the mechanic said your abs plug deeps was bigger and just because computer can not connect to the abs pump i mean abs plug deeps was bigger then before ok again i bought this plug and i changed but same now i dont now what should i do?is ABS or EPC does not work ever or dose not connect?my ECM or EPC part number is 06F 906 056 GL while i want to buy ECM does it need buy the same number i mean 06F 906 056 GL ??


when i say plug terminals were bigger i mean this. that i show in this picture


i changed both now ABS pump& plug but same


The connector you pointed out is a burnt out socket. At some point in time that specific socket in the wiring harness shorted from a bad connection and has now burned out that socket hole. You will need to replace the entire plug to fix this problem... which involves replacing the entire wiring harness... if your lucky you can get a new plug and just remove and reinstall it.. you can also try bypassing it by cutting out the bad plugs one wire and make a secondary plug for it.

i did it but my issue still continue


new abs


Ok then the next step is to trace the wiring harness Back to its source. This will be the cars ecm (computer) check all and any wireing attached to the one wire you replaced the harness for for signs of burnt or fragle cassings. If a wire heats to a certain point it will make the rubber got brittle and crumbly these are the signs you are looking for. See if a local dealer can provide you with a wireing diagram of your car and use that to trace the wires route. I hate wireing problems because they tend to be hard to find when they are embeded in large clusters of wires. if at best you may find a blown relay for the abs system.


the plug is no longer an issue since the damage is fixed there and jsut for clarity you do infact have the right plug harness instlled now.
