Default wtf??

alright so i go to check the ECM for error codes. i connect pins A and B, being the two rightmost pins on the top row of the Assembly Line Data Link, expecting the "check engine soon" light to start flashing. but instead, the radiator comes on. :skep: :confused:

No A-B top 2 right should be shorted prior to key-on possition is correct. Then turn on key and it should start flashing codes. Do not short A-G. The fan will come on. It does on mine at least.

The fan should come on and then your SES light should blink code 12, trouble codes, code 12. The 12 just means "entering diagnostic" and "exiting diagnostic".
