Yesterday my ABS light came on,

Here's the brief story, cleaned the car yesterday then left to go to work, stuck the new iPhone charger in, started up the car and the abs light went on and has never went out again, now I'm sure the charge is just a coincidence but not 100%?

I have checked the rear lights, all working, the brake fluid level is fine and there are no ecu error codes stored.

Anyone any ideas?

 

Fuse?

Or when you were cleaning it did you manage to damage a sensor at a wheel?? Unlikely, but....

 

try unplugging all sensor leads and re connecting as a slight increase in resistance on a plug due to corrosion could throw the light on, failing that you should be able to test the wheel sensors with a multimeter to see if they are ok. Well you can on ford anyway I presume they will be similar in operation. I would have though that its just connections though

 

Never thought of that but nope unfortunately the fuse is good

 

Hmm now a stupid question for da where are the sensors that all need unplugged?

Thanks

 

Sensors are located on the wheel hubs, jack up remove wheel and look behind hub.

 

Thank you kindly

 

Rear brake sensor failure is fairly common. You need someone to check ABS ECU error codes to determine exact problem.
