Dreaded Pull Key Wait 10 seconds AFTER LMC5 install











- Did you follow the written instructions provided TO THE LETTER? There is a youtube video that does not follow all the steps. I have read that there can be some issues after installation if not installed exactly as written.
- Did you do the brown wire install? (as already asked) I did a lot of research before installing mine and read several cases where the fault continued until the brown wire was installed. I decided to go ahead and do the brown wire on my '04Z. No issues since (knock-on-wood!)!!
I have also heard that Richard (owner) at Compliance Parts is a great resource if you are having issues. Their number is (855) 565-8388
Good Luck!!

The previous owner had the issue all the years he had it, not certain how it didn't drive them crazy. I have a new ignition switch I was planning on installing, but figured I would try asking Richard and borrow from all his years of experience, waiting to hear back. Low battery is probably not it as previous owner had replaced battery and it meets the specs Chevy list. I was thinking of having a new key made, but the three I got with the car all have the same issue so it is not likely. Perhaps the BCM is bad? I really don’t want to have to get another one with different keys, not certain if a new/used/replacement BCM can be programmed to work with my current keys?
So I will be watching this thread to see if any useful information that applies to my situation manifest itself.

Definitely search this but there is a data reset operation using the battery terminals. I think you reverse them.






My car is older now, with older electronics, etc, so I decided to "play it safe", and install an LMC5. As "MacA1979" said, in an above post, you HAVE to follow the instructions to the letter. I set out to do the "brown wire mod" right from the start, but didn't fully read that part of the instruction sheet. Yes, I clipped and capped the "brown loop" that comes out of the LMC5 itself, but failed to continue to read the instructions, where it says to connect the LONG brown wire from the LMC5, to the harness, in place of a brown wire that you remove from the harness, and subsequently cap off.
When I had the LMC5 installed incorrectly, I got the "pull key" message, as well as the "service column" error messages, AND the 2MPH fuel cut off. I was initially short on time, and had to back the car into the garage, and with the fuel cut off, it was a bit of a challenge. Later in the day, I went back, re-read ALL of the instructions, found my mistake, fixed it, and now everything is working properly.

I bought my 02 Z06 a few months ago and it already had the LMC5 installed. I have noticed that when I jump in and fire it up, I will get the dreaded message about 20% of the time. If I let the gushes sweep and settle before engaging the starter, I never get the message.
thanks
