THIS IS FOR THE ABS HIGH PRESSURE CKT. THE FLUID LEVEL FOR THE ABS MODULATOR IS LOW, ADVISE TO REPLACE THE ABS MODULATOR AND ACCUMULATOR AND BLEED SYSTEM...REPAIR=$1432.01
It started a couple of years ago and no mechanic could figure it out. Yesterday a different mechanic found the hydraulic leak problem. Now I know why the light is on. Currently 268,891 miles.
71,000 abs modulator and accumulator unit replaced at cost of almost $2000, including parts and labor at dealer. Modulator remanufactured only and comes with 12 months or 36,000 mile warranty. Then again at 104,000 miles it is leaking again, and needs to be replaced at an even bigger expense. Choices are to repair car or buy another car! Seems like it should be a recall item since it is dangerous impacting ability to have braking power.
AbS light on and not working
the leak is a minor one caused by failure of an O ring on bottom of ABS unit. the fluid leaks from high pressure side of system back to low pressure side, so there is no loss of fluid from the system, but the booster pump will run continually until O ring replaced.
abs light comes on when placed in1st gear and goes out until restartes will not come on in reverse
