I was wondering what the best scan tool would be for an LS1 powered Holden Commodore ,meaning best value for money? delivered cars but I disagree with that,what I mean is that people have been saying they're OBD1.5 when in fact they have been confused by the Buick V6 powered Holden Commodores which have been OBD1.5 from 1993 up until 2004 in Australia when they ceased fitting the Buick engine into a Holden. People have been saying in Australia that the LS1 powered cars are different from the U.S. That's meaning they don't read codes from my Commodore due to a hardware problem within the scan tool itself,all I get is live data on both scan tools but no fault code retrieval. I was wondering if there is a chance both scan tools could be faulty? In this case I get a pending P0113 code on both scan tools as shown here :. Note my car uses pin 2 for the signal wire on the OBDII port, now my fathers 2014 model Holden Colorado uses the ISO 15765 or CAN BUS OBDII system which Holden has used since 2006 in all of their cars in Australia,this car uses pins 6 & 14 for the signal wires, I switched on a code by disconnecting the MAF meter as shown in this photo:. Note I don't expect there to be any stored trouble codes which don't necessarily trigger a check engine light,etc but I am getting no pending codes displayed either :.
I bought it on Ebay after a seller had used it once on a Mitsubishi, I can't be specific on which models it covers but they don't use the same system as General motors,same problem next photo with the stored trouble codes :. This OBDII scanner which is also supposed to read a GM car such as mine isn't recognizing the fault,the only time it has worked for me is in 2012 when I had an air leak in the evaporative emission control system,it recorded a stored trouble code then never worked again,all I have been able to retrieve is live engine data,now to try another scan tool :. The engine symbol with the lightning bolt through it is telling me the car has a problem with the EFI system,but here's where I fall short :. I have a 2002 model Holden VY SS Commodore which runs the Chevrolet LS1 engine,so is SAE J1850 VPW protocol because it's the earlier OBDII type, well, I've got this problem :.
