I've got an LPG converted Accord 2.4 Exec 2004. I recently had a 10 mile an hour front end shunt. So insurance company took the the car away to the repairers put a new bumper on it and what not. So the car gets dropped off by a tow truck, I look round the car all looks good, sign the two truck drivers sheet and he leaves. I jump in the car a take it for drive, immediately the amber warning triangle pops up and then about 100 meters down the line the VSA light comes. Never had the issue ever before, not even after the crash. So I call the repairers, they say they'll take it away to check. So a few days later they pick it up and keep it a couple of days. I get it back the VSA issue is still there. The accident repair centre say their own auto electricians checked it over and couldn't find a fault, so they sent it Colliers Honda. From the receipt they gave me from CH which totalled about £40, it looks like CH only spent about half an hour on the car. This is what they concluded :- "ABS WARNING LIGHT ON CHECKED WITH HDS NO DTC'S STORE BUT VSA LIGHT ON DAS AS NO DTCs STORED & CAR HAS GAS CONVERSION WHICH IN TURN PUTS THIS WARNING LIG POSS FAULT DUE TO GAS CONVERSION INSTALLATION" The LPG conversion was done back in 2008 using a top notch BRC LPG system and is running real sweet. As someone who has done many LPG conversions (although not this one on my own Accord as I bought it like this), I say what Collier's concluded is total bull crap. So now accident repair people are saying its not their fault I'm left with a VSA issue to sort out. Can anybody give me any pointers in diagnosing this issue ? Are there any commonly failing components on the VSA system ?
