Intermittent SES - ZR-1 Net Registry Forums

c4zr1 · 03-05-2012

I have the same problem with my 92. The SES light comes on intermittent. I drove it to a Make A Wish car show last Friday. (I do have a Haibeck chip that has my power key on all the time.) No SES light on and my power key light was on when I first left to drive to the show. By the time I drove down to the show about 10 miles the power key light went out and the SES light came on. I thought the chip would keep the power light on all of the time, but no.

When the show was over yesterday afternoon I drove the vehicle home the long way around hoping the SES light would go off. I drove it about 10 miles with the SES on and still no power. I got 2 blocks from home and the SES light went out and I had good power so I took it out for another 6 miles and the SES light never come back on.
Last year I did have my ECM rebuilt. I am thinking about taking out the chip and going back to the stock chip to see if that clears it up.
My next task will be to try and do the paper clip jumper and see what codes I get.
