Scope & Scan

  • Our first vehicle is a 1999 Toyota Rav 4 2.0L with an automatic transmission that came in with the customer concerns of running rough, stalling and an illuminated Malfunction Indicator Lamp (MIL). 
  • We had a 2006 Volvo XC 90, 2.5 L 5 cylinder with 128,852 miles on the odometer come in with a complaint of low power, stalling and excessive oil consumption.
  • A 2008 Porsche Boxster with 18,900 miles came in with a TPMS (Tire Pressure Monitoring System) problem.
  • As you are working on today’s vehicles you won’t be able to fix many different vehicle problems unless you are able to reprogram the vehicle. Our case in point is a 2006 Ford Explorer with a 4.6L V8 (Figure 1) that came in the shop with an EVAP circuit and O2 heater circuit problem. 
  • The TST/ATTS training center is also a full-time shop located north of New York City and its keeps me current on the problems my students and readers are facing. Here are a few of the recent challenges we faced.
  • Following a good diagnostic plan can ensure success, no matter what you encounter.
  • Since we are concerned with today’s software reprogramming issues, we will discuss the generic J2534 unit and how and why to use it.
  • With young techs working in my shop, I find myself spending as much time in the bays with them as I do upstairs working on my training materials. While it makes for long hours and hectic days, it also keeps my own diagnostic skills sharp, and I enjoy passing on what I’ve learned to the guys. Toyota EVAP Fault First First up is a Toyota Avalon (even though the Toyota Scan tool ID’d th
  • This problem vehicle was a 2005 Ford Crown Victoria 4.6L V8 with a complaint of sometimes being hard to start. The retired owner of this Ford does not drive it much. In fact, this vehicle only had 25,000 miles on the clock. 
  • First on the list this month is a 2003 Toyota Highlander 3.0L V6 that came in with a few Diagnostic Trouble Codes (DTCs), then comes a Porsche under water. 
  • The customer came in with a complaint that his Check Engine light was on. A quick scan easily showed the reason for the complaint. A P0401 (Exhaust Gas Recirculation (EGR) Insufficient Flow) code was found when I checked using Global OBDII’s Mode $03. 
  • Vacuum leaks and fuel delivery problems are common causes for these common codes, and you might be tempted to focus immediately on these. But there are many other causes that can illuminate the MIL for the P0171 and P0174 DTCs that you also need to consider.
  • The first story shares a lesson on not getting caught with your pants down, the other is a tale of a BMW clutch gone sour, and the third? Well, the third is just for your enjoyment! 
  • New DTCs appearing after a repair is more common than you might think. The reasons why are several, but the most common are a failure to make sure all the OBDII test monitors are Ready, failure to address pending Diagnostic Trouble Codes (DTCs), and not investigating the cause of Mode $06 failed test results.
  • Pre- and post-repair scans are becoming a bigger and bigger part of repairs, and establishing a working relationship with a local mobile diagnostics professional is a great option if one is available in your area.
