The AC drain on my 2004 Montero Limited backed up, causing water to drip into the passenger footwell. Shortly after this, the traction control and ABS lights turned on. I'm thinking a module shorted out? Everything else works, the car drives fine and the 4wd engages in all modes. Is the traction control built into the PCM/ECU or is it a separate module I can replace/repair? Any input is greatly appreciated. This Montero is new to me, in great condition otherwise so I am assuming the water ingress and sudden disabled traction control are NOT a coincidence.



I fixed the AC drain issue, so I'm comfortable replacing any electronics in the cabin at this point.
