George wrote in to discuss the topic of fixing check engine lights with online service manuals and inexpensive scan tools. Here’s what he said: Thanks for the response about online auto repair manuals. I understand what you mean about All-Data and Michell’s in reference to their auto repair information quality. I had looked at the two, and tried the “demo” on All-Data which actually let me view (as you know) actual info like I would get in a subscription to a particular vehicle.
The one downside I [thought] was when I looked up DTC’s and test procedures for them it always referred to the Manufacturer or Dealer type scan tool. Even though it listed, in one place, a choice of tools (manufacturer/dealer, other, etc) to view this info for, it said that info was not available for any except the Manufacturer diagnostic tool?
I got to this by clicking on the Honda demonstration vehicle since my daughter has a Honda (older than the demo, but I was looking to see what all it included). I then clicked on Power-train Management and then Computers and Control Systems all these along the left column. Then I clicked on Reading and Clearing Diagnostic Trouble Codes under “Testing and Inspection” in the right column.
This brought me to a page which had links to With Manufacturers Scan Tool, With Generic Scan Tool, Without Scan Tool and “Clearing Diagnostic Trouble Codes”. If I click on Using Generic Scan Tool, I get the page saying the Manufacturer doesn’t provide auto repair information for this. While it may be painfully obvious to most, I wasn’t sure the info would all work with a tool like the Actron CP9180 or the Auto-Xray AX6000 or such.
