Understanding Vehicle Technical Service Bulletin Process?


What is a Technical Service Bulletin


Where should i go when TSB is issued for my vehicle?

Is it free repair or service at dealer if TSB is released?


Below i will explain you Complete Theory of TSB in Detail :----


A Service Bulletin in the automotive trade is called a Technical Service Bulletin (TSB). TSB's would be better described as a problem/solution bulletin. TSB's can cover a large array of problems.

Let's start with the repair manuals and time guides. It is not uncommon for the diagnostic or repair procedure to be incorrect, just plain wrong, in the repair manual.

Nobody is going to reprint the whole manual, instead TSB's are issued to alert the tech and be used as an insert. TSB's report on updated repair procedures and new parts to replace problem parts.

  • TSB's have fixes for some of the strangest problems like dash itches to providing information on just how a component or system should be operating. 
  • TSB's also report on warranty information and in the event if a warranty is extended due to product problems. On today's high tech vehicle's performing a TSB search is nearly second nature and just part of what an up to date repair facility does for its customers. 
  • One final note, TSB's are not be to confused with safety recalls. The work performed for a Safety Recall is free to the vehicle owner. 
  • TSB's are there to aid in solving problems and providing up to date repair information. Repair is not free unless the vehicle is still under warranty.


Gas Gauge Acts Crazy

Gas Gauge Not Performing right



Jeep Grand Cherokee, Nut'zy Gas Gauge

Q: The gas gauge on 1997 Jeep Grand Cherokee will drop to empty then return to 3/4 to 1/2 tank every so often or until I fill it up or the gauge goes below half tank. The dealer said I need a new pump but there isn't anything else going on. Any suggestions?

A: Your vehicle is notorious for gas gauge problems. In fact, there was a safety recall that affected about 400,000 Jeeps including the Jeep Grand Cherokee built in ‘97. The problem was the gas gauge would report that there was enough fuel when, in reality, there was not enough fuel and the vehicle would be dead on the side of the road. I’m not sure that your Jeep qualifies for this recall but it is worth checking into. Also, you’re not being told the whole story. If your Jeep dealer checks his/her Technical Service Bulletins (TSBs) they will find TSB# 08-19-97 that provides the part number for a replacement fuel sending unit that is sold separately. The TSB goes on to identify which of the 3 possible replacement part numbers that would fit your Jeep. The gas tank still has to be removed to service this part, but it is at a considerable savings to the vehicle owner compared to buying the complete fuel pump module. The fuel pump module is a new fuel pump and sending unit all together and is a bit on the pricey side. One last note, if your fuel pump has 100k and has not be replaced I would suggest installing the complete module. About any fuel pump with that kind of mileage is living on borrowed time.
