03 h2 and 1700g

Did a remote start/alarm on an 03 H2 yesterday using the 1700g.  All seemed to be fine.  If you've done one, you know these things aren't difficult at all.  I even drove the vehicle about 5 miles down the road and back.  Just got a call from the customer saying that its shutting off after remote starting and even shut off on him while sitting at a stop light. He also said something about a low battery indicator on the message center.  My first guess is that its something to do with the 1700g.  I, along with a lot of other installers, have had a few problems with these before.  Any sugggestions on what I should look for to find out if it is, in fact, the 1700g?  I hate to replace it with a different module and send him down the road again only to have his problems reoccur.

never used a 1700g and couldnt imagine how it would cause the car to stop while he's driving since the vehicle is running on it's own, not by the power of the remote start. two things i can think of...

1. check if the battery post is loose...generally what causes that problem

2. check the tach wire. if you ground the tach while the vehicle is running, it will shut off. maybe the connection or tape job was bad

the engine shoud idle around 900rpm, 500 is pretty low. try getting the tach from behind the instrument cluster. its not that difficult to get it out and theres only one plug behind it. you want the white wire, theres only one.
