We know that when the stepper motor is not moving in the dashboard, it could be caused by the bad chip driver or that motor itself. Most time, it's not easy to find out which part is really broken. Normally we just buy a new stepper motor to install or a new chip to solder. If not lucky, you maybe have to buy twice!  It's really cost time and money. Comparing soldering chip, to remove stepper motor is much more easier. Why not to make a tester which can check the motor itself? Then we are able to locate the problem faster. That's how the KR60048 comes out.  This device can test most all kinds of stepper motors. Also we are proud of that it not only solve our problems but also make little help to rebuilders from Europe & USA.

We met a lot of transmission plate problems when repair Mercedes Benz. Most time, the broken part is only the speed sensor in the plate. To exchange a new transmission plate is quite expensive, but to replace theses speed sensors, is not only cheap but also a fast solving method. How to replace the speed sensor? Step 1, Confirm the broken unit is the speed sensor. The diagnostic result will show: the turbo speed sensor no signals or fault... Step 2, Remove the broken speed sensor from the plate. That's the hardest part we will face, as the speed sensor stay too tight. Here we normally use two ways to remove it, A,  Tools you need, a electric drill, a screwdriver and a hammer， below is the removing process B. Tools you need: a speed sensor removal bar, a hammer In both ways, please note that DO NOT break the yellow film, or any other part, especially using hammer. Step 3, Glue the hole( not too much), and insert a new speed senso

When your BMW's headlight, steering light or window lifter out of control, it may caused by the broken of headlight, steering light, lifter itself, but in most case, these malfunctions should be caused by a faulty FRM. To locate the problem is always the most important as well as the first step you need to do. Then customer can use our KR60022 testing fixture together with programmer VVDI, XP or CG100 to check whether the problem  happens at FRM or not in a fast way. How to do, 1, Connect KR60022 with programmer VVDI, XP or CG100 to check the MCU (MC9S12XEQ384). If the MCU is empty or losing date, congratulation, you get it. If the MCU is good, then you have to check headlight, steering light or others one by one. 2, To replace a new FRM is quite expensive.  But according to our experience, the only part you need to exchange is the MCU on it. So to buy a new MCU(MC9S12XEQ384), use the X431pro、Autel 908、Golo to program it with full data, soldering the new MCU back and t
