TSB EG-0127T-1014 (SW update to avoid cylinderhead gasket failure)

Techstream ($10,000 plus subscription fees) falls into my definition of a fancy OBD scanner. I've got a $40 bluetooth adapter, and an Android phone with a couple of free apps.

That's what I thought about the "shop supplies". Maybe it's what they used to do their inspection I never asked for. Maybe it was the lubricated condom so I didn't feel it when they screwed me.

I guess I'll fire up my adapter, and see what comes out of the phone when I look at it.

 

I found a free OBD2 app that works to get the CALID parameter out of the ECU. I wish I would have done this before scheduling an appointment. I would have been better positioned to know whether I needed this before spending the money, what was available, and whether they actually did the upgrade.

 

The Car Scanner app reads calibration ids for the ecu, bcm and immobilizer. For the rest of the systems it provides a four digit “part number”.



The European tsb adds credence to the thermal cycling and pinging when carboned issues, both easily demonstrated.

 

You must be looking at the full bundle that includes the ruggedized laptop and $500 dongle.

Most people other than a real-busy shop are going to pick up their own beater Windows laptop to download the software on, buy a decent dongle, and just pay a short-term subscription as needed. No need to scare 'em off with a wackadoodle price for something else.

 

There are options to have a full Techstream with online library and ecu reprogramming

1. Toyota sells a Techstream Lite package for $1645 which is a discounted bundle of the Mongoose dongle ($545) and a year of Professional ($1360) level software. You supply a Win 10 laptop.

Professional Diagnostic level is required to access and program the ecu file which is the center of this thread’s discussion.

2. One might think the $545 dongle alone or equivalent and a $70 two day subscription could work.

3. You have the dongle and buy the $70 subscription.

The question then becomes do you want to risk bricking the ecu versus letting a dealer do it for $150 or perhaps finding an independent Toyota shop who has the access and equipment.

 

I don't think I'd be worried about bricking anything just by doing a query for what calibration ID is already in there.

I'd worry more about using the setup to actually try flashing the update. But I didn't think that was the question.

I definitely go to the dealer when I want an update flashed, just so they can be the ones who get to worry about that.

 

Posts 82 and 83 already provided low cost apps for reading the calibration id.
