My CL started very briefly flashing the red abc warning message and chime, whenever I go over larger bumps in the road . It flashes for literally much less than one second - as soon as I go over the bump everything's fine . Fluid is full.

I assume that the loading / unloading of the suspension when going over the bump is causing some sensor value to trigger an error. Anyone had this issue before ?

Could it be the accumulators ?

I don't have another abc equipped car to compare it to , but my ride has always been pretty stiff (40 series 18 inch tires)

Of course its much stiffer than my s430 with 16 inch 60 series tires, any easy way to diagnose the problem without star das?

Most likely the accumulators. Probably a good ideal to replace both and the pulsation dampener at the same time. Pretty easy job to do.

Isn't there three of them, two up front and one in the rear?

1 accumulator front left wheel well, 1 accumulator rear above passenger exhaust by spare tire, and 1 pulsation dampener on the front right just behind the wheel.
