Default Ign Switch Question

Can a ign switch cause a C1277/U1040 code?

In my honest opinion,, I would have to say NO.. Is it a History code or Current code? Try clearing it and see if it pops back up.

I do not understand how remove panel to ck ground G108/G201.

G-108 is on the passengers side frame rail inboard of the battery. Follow the the small battery ground wire down to the frame. You will find a stud with a 10mm nut. G108 is the small wire under that larger ground wire. Spray with PC Blaster and remove the nut. Clean the frame, the eyelets and the nut. Retighten

G-201 is under the passengers side door sill cover. Pop it up and off and its in the triangle at the door A pillar.

Bill,


Thanks,I was looking in the wrong spot. Will ck and clean.

The reason i asked about the ign switch is from a thread. One member had the same two codes. He cleaned his ign switch per your thread. No more codes. Another thread same codes,ABS the problem.

In your expert opinion,if all grounds,fuses,were ok.Would you repair or replace the EBCM?

Since the ABS wth code C1277 is not repairable.I can purchase a rebuild unit from ABS fixer.


Thanks

Wahoo
