Question: Why do I have no power at the tip when I am pressing the power switch forward but the red LED is on? Answer: The power switch goes through a lot. It is one of the few things that go wrong with the tool. The switch is a consumable that needs to be replaced on occasion. We have made it really simple to not only change it but also buy a new switch. The switch can be snapped out and replaced in seconds. Review: FAST relearn - I work for a dealership. When we replace an OEM sensor, we have to perform a relearn (obviously). That means walking around the shop to locate the diagnostic module (waste of time), connecting it to the vehicle along with a laptop containing specialized software, booting up the software, getting logged in and to the correct screen, then finding yet another tool which activates the sensors (five times each), uploading the sensor codes to the ECM, and finally driving the vehicle a quarter mile which completes the relearn (if you don't drive the vehicle, the Low Tire light will stay on for the customer, and they will think there is a problem and degrade your reputation). Well, I used the TS601 at a different shop and was surprised to find it it costs $350-ish. The other major TPMS relearn tools go are between $1k and $2k, and some you can't update without paying a fee. So this tool, I powered it up, selected the vehicle, scanned each sensor ONCE, uploaded to the ECM, and was DONE. Didn't even have to drive the vehicle. This tool reduced a 10 minute job to less 2 minutes. We are a dealership, so won't be using after-market sensors but I *do* have experience programming after-market sensors with this tool at the other shop and let me tell you, it is just as simple. While one tech was doing the actual replacement of the sensor, I not only programmed the new sensor but also did the relearn - all while the one tire was on the tire machine. Parts availability is solid, you can get the MX sensors for fifty bucks each at one of the major auto parts store, and they also carry just the stems both metal and rubber - these are serviceable, because you're supposed to replaced the stems every time you open the tire. The OBDII diagnostics / codereader is super awesome to have. Compared to other scan tools, this one takes longer to identify which protocol a vehicle uses, but it's still less than 30 seconds. It gives the code and its description. I never opened the manual but I hear it needs a re-write, and the on-screen instructions are not always correct. Review: Finally something that will program my 2013 Civic. - I have had problems with the sensors on my 2013 Honda Civic LX for a long time. Even after having the sensors replaced, the tire shops failed to realize that the sensors need read and then written to the ECM in their specific locations on this particular model. I finally gave up on explaining this and purchase the TS601. Within 20 minutes I had cleared the error codes, read the sensors, and written them to the ECM via the ODBII port. Problem solved. ## Features - 【Upgrade of TS408/TS508】Based on the functions of the TS408/TS508, the TS601 adds a more powerful data stream function, which can observe the dynamic changes of data to help solve difficult problems.Its service function is more helpful to rewrite the tire pressure reference value for GM, Ford, Chrysler, modified wheels. - 【Powerful &Professional】Capable of fully diagnosing TPMS problems as well as activating TPMS sensors and reading/ writing sensor ID to the vehicle ECU with the included body interface.
