10 years ago I put a 1-4 skip shift bypass on my car. Has worked flawlessly until last week. Without touching the bypass , the amber light now seems to be functioning as originally intended.
Just prior (1 week), I had replaced the PCM and all was well. Now my engine is running great and I am yet again, annoyed.
Any thoughts?
It was just a little plastic plug in CAG shift bypass module. Nothing done to PCM. From the moment I placed the CAG bypass the light on the IPC disappeared (as intended). Has been that way until last week. Following a new PCM It began. But I placed that module in the back near tranny myself. Never touched the PCM. Odd. But then again considering all of the recent gremlins in my car, who knows?
I do have the PCM tuned and you may have hit the nail on the head. The tuner may have tuned the light out and I just never realized it at the time, now with the new PCM (not fully tuned yet) it's likely back. So thanks for the bump to get the gray matter working.

Reason: Additional info
When you just had the light illuminated were you able to shift to 2nd?? If so the bypass module is working as it should.
I have never heard or seen of a case where the light goes out with just the CAGS Bypass. Shifting to 2nd is allowed but light remains illuminated......
Same here. I have the CAGS by-pass installed on my car, did it 11 years ago, but the dash light still comes on, if I'm accelerating slowly.
i got my 1 to 4 shift light switched to a shift indicator light by my tuner. don't really use it much, but an interesting feature to have if you get it tuned.

I like that idea! might have to do that to mine... Factory shift light
Does it only work when in 1st gear? or can you program it to any gear?
