OK, ABS fixed.

Windshield replacement (which eliminated water on the cabin floor) did not correct the problem with the ABS, but did stop water from coming in nonetheless.

Wasn't an ABS CM problem either.

Finally took it into our trusted shop and they did diagnostics on the ABS / TCS system and found that only the left front hub bearing was bad and intermittently causing the sensor to throw not a C1242 code, but a C1232 code. Third time the left front hub has been replaced since the van was new. Last hub had 130,000 Kms on it.

Didn't charge me for the diagnostic time, just the flat rate to re and re the left front hub with a new one.

No background on why the code originally appeared as a stray C1242 periodically.

Now I have to pull the interior panels from the right rear and figure out why my power sliding door stopped working. It could actually have been caused by water. Logic controller thinks the door is on the primary latch and buzzes when the van is in gear and sliding door lockout is turned off.

Oh joy!
