CEL appear 3 months after I changed catless DP

[baobao]

Hi, yesterday I just find the CEL appeared in my dashboard. But when I would like to check the reason of CEL in the system, the system didn't show anything about the CEL. In vehicle status/ check control, I can't find CEL there.

The only thing I think may cause my CEL may be the catless DP. But I change to catless on June. And I run catless for half months, no CEL. Then I received my PSU and I did a BM3 stage 2 tuning. Since I didn't see the CEL for the half month, I didn't choose the 'clear CEL' function when tuning. And I run for about 2 months without CEL until yesterday.

So can someone tell me what is causing my CEL? Anyone run catless can you please tell me, are your CEL looks like mine? Only in the dashboard but no CEL in the check control/system? Thank you!

Did u try reading the code with BM3 Diagnostic ?
That's a good starting point

I used the bm3 Diegnostic, and read two error codes:
180001 Catalyst: Efficiency Below Threshold
180101 Catalyst 2: Efficiency Below Threshold

I googled them but find a lot information about "P0432 code". They seems to related to DP but I am not 100% sure.

Can anyone help me confirm the cause is hatless DP? And is there any documentation about the bm3 fault codes? Thank you!

If serious, there is a [Config] option towards the upper right hand corner of each BM3 OTS map.

Select the [OFF] value under the Catalytic Monitors (CEL).

Save Changes then re-flash the map.

Thank you! I have done this and the CEL was cleared. So I am assuming this function will only clear the codes related to catless DP, if any other part has an issue, the CEL light will still work and appear in the dashboard to warn me. Correct me if I am wrong.

You deleted your Cats when you went catless and cleared the CEL so you should be good to go mate!
