Will INPA/DIS diagnose EKAT system issue?

[1999750il]

Hi all,
Well its been weeks and I still cant figure out whats causing my CEL.
I recently ordered a INPA/DIS system and hope that there's a way to diagnose the EKAT system and see what causing the CEL. My peake tool scans 2E which is EKAT status 4 Heater disconnection side 2
So far I have verified voltage to EKAT module under pass seat, tested continuity between module and cats..no noise or smell from exhaust..car runs fine.replaced starter/ekat battery. When I probe the wires at the cats with a multimeter..i never get voltage...even though when first started cold there should be up to 30 seconds of voltage to the heaters in the cats. Has anyone ever come across something similiar?

Hi you can read stuff like the voltage of lamda sensors before and after kat and lots more with inpa.This is a bmw tool that bmw use to diagnose their cars.

Hi Rondo,

Thanks for the info. I believe the cats are working fine..theres no rattle noise or smell and the car idles/runs fine. I also replaced all 4 o2 sensors.
I was hoping there was a way to test the EKAT module itself to determine if thats what is causing my CEL. I cant figure out why I cant get a 12 volt signal at the cats when I probe the wires with a voltmeter.
Anyone have a clue about what program would diagnose this 2E error code?
Thanks

are you SURE that you connected the O2s correctly, with the correct cables, after you swapped them out? I have read that they can get easily mixed up. . .

Hi MK

Yeah..I removed and replaced each pre and post sensor one by one. Its weird since the car seems to run just fine...but I get the CEL 2E from my peake tool every so often. The car has new plugs 2 new MAF sensors, the cats seem finetoo. I just cant figure out why I cant get 12 volts at the cat wires under the car. I was hoping someone on this forum had diagnosed these damn EKATs before and had some pointers for me.
Thanks again for your advice.
