He actually read the code on a Cummins M-11 engine, could NOT read the Allison transmission and also the ABS computer. ABS was my biggest interest and I got nothing. The second biggest interest was AT, and there was nothing either. Then I tried a 2006 crossover truck and was amazed that it couldn't find a way to communicate through the OBD-II connection. Since it was only connected in one test, which was my lowest priority, I have other tools that can easily read this. Buy the best tool from someone you trust. I don't trust these sellers. They have delayed the return process and are requiring me to pay for the return postage for the defective item. I figured I could trust Revane with a refund. That does not exist. Find the bestseller.
