I got in my car last night and had the ECC lights flash when I started it.

I checked via the OBD port and got the following error codes.

126
132
151
211
221
231
233
235
311
312
313
314
315
324
325
411
412
415

I thought they would never end.

I cleared them and started the car, ECC worked fine. Next time I started the lights flashed again, but I kept driving thinking I would check them in the morning.

When I started the car this morning the ECC worked fine, and has continued to do so all day.

Reading some old posts it says to check the earthing of the ECC. Where would I find this earth?

Any other ideas?
