EOBD Practice Task - Tuesday 25th November 2014

In the Driving Seat with the Goodies!

Today we were given the perfect opportunity to try out the latest diagnostic tool acquired by the College Motor Vehicle Department.  It was a touch screen Autel Scanner and has a very user friendly interface (at least it looked like it was, as I didn't want to cause any damage by wrestling it out of the hands of Isaac)!  We were assigned to 3 different types of vehicles from which to obtain DTCs.  One was the Toyota Auris EEV (Hybrid), another was the Citroen C4 (CI) and the final one was a Toyota Avensis (SI).  Having gathered all of the respective vehicle's information, and researching a little regarding engine Euro Ratings, we then began our task, commencing with the Hybrid.  Immediately noticeable was the speed at which the scanner operated and, with the latest information stored, compatible with the EEV DLC interface.  With all DTCs recorded we then cleared the codes and re-ran the search, which returned no results, so successful.  I sat in the rear of the car in order to: a) Obtain clear view of Isaac operating the scanner, b) Obtain clear view of the scanner operation methods, and c) Sporadically and repeatedly ask Isaac "are we nearly there yet" and "can I have an Ice Cream", "I need a wee"!

Listing of Capabilities

We then proceeded to the Citroen C4 and undertook the same operation, only this time a fault was returned which we could not clear.  It concerned the EGR valve and, due to its' location, was not able to be further tested.  Further investigation required.  At the point of cease works, we were incomplete on the task, requiring to test the Avensis, and in conjunction with the use of a break-out box and Picoscope. A very interesting task which I look forward to resuming on Monday.
