Important note on DA-VINA 2534 upgrade

Dear customer,

Maybe you have heard that DA-VINA 2534 Jaguar Land Rover J2534 Pass-Thru Interface hardware has been updated to the newest V4.4. The new hardware is claimed to support 2014 Land Rover vehicles. But we are sorry to tell you that the DA-VINA 2534 you bought from us should not be upgraded.

One of our customers had tried to update his DA-VINA 2534, but only got his device locked. This is why we suggest you not to try the latest DA-VINA 2534 hardware but just use the V4.0 one. However, although the hardware is not available, the latest DA-VINA 2534 software is totally safe to install.

We are very sorry for the inconvenience and will let you know once the new hardware is safe to use. If you have any friends that purchased DA-VINA 2534 from China, you can also remind them not to try the new hardware at present; otherwise, their tool may be locked as well.

How to fix Buick GL8 acceleration problem?

I repaired a Buick GL8 that could not accelerate while driving last week. According to the car owner, the Buick was equipped with a 3.0 engine and a 4T65E automatic transmission, with 120,000 km on it.

The owner told me that it could not speed up when he was driving the car, which made it extremely difficult to climb up a slope. Every time he came to an upslope, he had to press the accelerator pedal all the way to push the car up the slope.

After I received the car, I first started to diagnose the problem by using GM Tech 2 diagnostic tool. Test result from the OBD2 tool showed that ther automatic transmission of the car was broken, so that the vehicle could not go faster than 130km/h.

Then I troubleshot the automatic transmission control system with the GM Tech 2 again, and pulled two error codes: P0756 and P0758. The former means 2-3 shift solenoid B circuit fault, while the latter means 2-3 shift solenoid B electrical fault.

After troubshooting the problem, I went a test drive and checked the data flow while driving. Then I pulled out the plug connecting the automative transmission, and tested the resistance of 2-3 shift solenoid valve, which turned out to be infinite. When I tested the resistance with other solenoid valves, their numbers were normal.
