  • 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. 
  • Since we are concerned with today’s software reprogramming issues, we will discuss the generic J2534 unit and how and why to use it.
  • 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. 
  • 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!
