On my way to work one morning my 2004 Tacoma’s check engine light came on. No big deal, everything seemed normal. No driveability problems. Assuming that whatever was wrong would still be covered under the 5yr./60,000 drive train warranty I took it back to my dealership. There I was informed that the problem probably would not be a warranty issue and the diagnostic charge would be $120.00 unless the fault was covered by the warranty. At this point I said go ahead and check it out. As it turned out it was a defective ECM (Engine Control Module)and would be replaced under warranty. The dealer ordered the part and a few days later it was replaced. End of story? Not quite. About a week later the check engine light came on again. Now I’m faced with another trip to the dealership and the possibility of spending $120.00 for the diagnostic check.
