Guys,

I'm sure this is one that some of you have experienced before.
My 2000 w 153,000 miles was last run about 2 weeks ago. Started it and let it ideal today. No problems. Went for a ride, put it in reverse and it stalls once I get rolling. It'll start right back up but will stall all over again in R or D once it seems to go above a mile or two. Only things Ive done to the car the last few weeks was change out the main belt tensioner and add a bottle of tech-ron. I'm getting no warning or check engine lights. Idle is smooth and other wise runs fine. Any ideas?

Thanks in advance,
Tim

 

No messages on the DIC.
I'll pull the codes now.

 

Pretty odd. I started it up again and no problem. Drove it around the block and it was fine. No codes are up. Kinda concerned though as this will be my wife summer car. Don't want to leave her stranded somewhere. Just chalk it up to sitting for 2 weeks?

 

Done and Done. I've got the compliance part ordered and on the way, and a battery tender on the car. Thanks.

 

I consider the LMC5 to be the best Column Lock problem permanent fix out there. It also does not require you to “undo” any previous CL attempts to resolve this issue. Their eBay ads have a good video that shows the install at the BCM. It does not cover everything in the written instructions. So, read the instructions and also here is some extra info. In some cases, the BCM timing is off just enough to cause some issues. They make several versions and they can swap out/provide one of these if you have any issues. Their customer support is as good as it gets.

Not uncommon for people to "put the column in a pre-lock condition" and not know it and then start with the install. In other words, they started with the column lock “energized’ even if it was not actually locked yet. If not actually locked yet, it will be as soon as you turn the steering wheel after the LMC5 install. It will then remain in the locked condition until you cause the motor to unlock. It will then remain in the unlocked condition since the motor is then unpowered with the circuits disconnected.

Here is one way to prevent that if your column locks and unlocks normally:

If the CL is functioning normally you don't not need the Unlocker, merely turn the ignition ON, pull fuse #23 in the I/P fuse box, turn ignition OFF, turn the steering wheel (left and right) and verify it is unlocked. Next, disconnect the negative battery terminal, re-insert fuse #23 and continue with the install.

Also the 1999 and later C5's have a column lock relay that can be unplugged or else it will be powered and could fail and drain the battery. The LMC5 written guidance provides this info. This relay is above the BCM.

They also have a great install video in their eBay ads you need to watch.

Mr. Sam

 

Yup! The LMC5 fixed my 2mph cut off

 

Installed the LMC5 today. Took about 25 minutes including watching the video and reading the instructions twice. Also unplugged the lock module thing per the instructions. Started it up 3 times went for 2 20 minute rides around town with no problems. Thanks guys for your assistance

 

Richard made a great product.


Mr. Sam

 

I did the LMC5 and pull relay 2 weeks ago and had to call Richard on a Saturday when I found I could not get to the relay. He guided me to another way of accomplishing the same thing with out major surgery getting to the Relay. They are great to work with and anyone with a C5 should be considering this maintenance.

 

Here is a weird follow up. Went for a quick ride in the car and it did the 1 mph stall thing again. I got the pull key with 10 sec message and then tried a different key and had no further issues. Is it possible that one of my keys (i got 3 with the car) is going bad? Or should I be looking for another issue?

 

Could be the key. Did you do the brown wire Mod when you installed the LMC5. The procedure is in the instructions. This will prevent the pull key wait 10 sec message.

 

So I did the brown wire mod (thanks for the reminder on that). Upon leaving the driveway it stalled out one more time but without the pull key and wait 10 sec display. Restarted the car and it was fine. It is a higher millage car (153K) so maybe its something else?
