I have 2009, 2011 & 2014 GM products. I typically use the release and raise air pressure method to excite the sensors. I have a TPMS tool to excite the sensors. The problem is, the sensors are a PITA to excite. Sometimes it takes 2 minutes to excite just 1 sensor. Sometimes they will excite really fast.

Is there a powerful tool that works well? or is it just a lazy sensor that doesn't want to excite ?

There must be an easier way like waving a wand over it, to excite it immediately.

Any recommendations ?

What tool do you have? There are professional ones. I have a $200 one that's a lot better than the $60 I originally had.

Which $200 tool do you have ??

I have one of these, and never have trouble triggering sensors anymore. I had a cheaper tool once before and had to beg and plead to get tpms to trigger... this is 2-3 seconds max...

I use a rubber hammer on the sidewall couple of knocks and it wakes up

CUB Programmable Universal Replacement TPMS Scan Tool.
Got one from Tirerack earlier in the year for $20.00

That is the tool I am having problems with. Sometimes it takes forever to excite the sensors. Like 30 seconds to 2 minutes...

I had similar problems the 1st time I used the Cub. I believe it was because it was not sufficiently charged. I recharged it the full 6 hours and it worked without delay.

I tried with the unit connected to an extension cord.
I tried putting in 6 Fresh AA batteries.

Same problem.

I can't imagine using the 6 rechargeable batteries fully charged would be any better than if it was plugged in.

Tend to agree but give it a shot. If it doesn't work then its likely the unit is defective.

This is what I have personally, it works but it is slow. The GM tool we use at work isn't always a lot faster but usually 10 seconds or so a wheel. However it's around $1k, so I'd be happy you don't have to break out the air compressor.

Mine likes a fresh set of AA's each time.

I use a Bosch EL-50448/OEC-T5 tool I got off the A site for $70 and it works great. Many guys on the Silverado forum recommend it and they were right.
