my abs light is on and it showing code 11 and 18. does any one know if this is fixable by just replacing the parts or something? i know code 11 is replacable but i don't know how to fix code 18.. code any one here help me? all this happen when i swap out the front strut and rear shocks, and i also put on some 18s.. thanks

 

oh yea , i have 98 gsr..

 

11 - wheel senor (open/short to body ground/short to power) FR
18 - wheel senor (electrical noise/intermittent interuption) RL

Look for a flaky/dirty/corroded electrical plug in the wiring for the left-rear sensor. The plug might be inside the trunk somewhere under the carpeting.

I don't know what code it would throw if the sensor just got full of crud, especially if you had to saw or drill that one $#&% bolt that's always seized. Steel shavings stick to the magnetic head of the sensor...
