No Service Engine Soon Light. Removed Computer to prob CKTs 340, and 439.
Egn on: 340 test light ON.
439, No Light.
The GM manual for the car Shows a ECM fuse, CKT 439, PNK/BLK w/ECM Fuse, and CKT 419 SES Light BRN/WHT w/gage fuse.
I can't seem to find the ECM FUSE, or the Gage fuse to the SES light.
Are they referring to the CCM fuse or Gage fuse in the Fuse Block dash board.
Been struggling of a week now, Please help!!
