Tango Key Programmer Synchro maker Volvo was introduced in Tango software update 1.95. The main function of this maker is to allow, the users of Tango Key Programmer that purchased it,to synchronize ECU and CEM modules found in Volvo vehicles.

In order to use the software you will need to load a dump file from both ECU and CEM modules in Tango software. In case that one of the modules is broken or the chip contents are replaced a file from a replacement (donor) module can be used.

Currently supported types of ECU and CEM contain the following chips:

CEM: 93C86, 28F400 ECU: 93C56,24C04, 95P08

Any combination of the above mentioned can be synchronized.

The main purpose of this document is to show and explain how to properly use this software.

First Start Tango software and select Dump Editor mode:

After that select Europe -> Volvo- > CEM+ECU

When loaded the software window looks like this:

The Synchronization of the modules begins with loading their dump files in Tango software, in the example used in this document the sync between CEM with 28F400 and ECU with 95P08 will be displayed. It doesn’t matter which file is loaded first

In this guide it will be demonstrated how synchronize the CEM module with the ECU.As a result of the whole procedure a new file for the CEM module will be generated by Tango and this file is synchronized and compatible with the originally loaded ECU file. The reverse operation – creating a new ECU file compatible with the original CEM file can be used instead, the procedure is basically the same.

Synchronization is started with loading the dump file from the CEM module:

Using similar procedure load next the ECU file:

If you press the Check Synchro button now, it will display the following error, because at this point the files of the ECU and CEM are not synchronized. NB: If the files are taken from a working car the error will not appear and will write “SUCCESS” instead.

To actually synchronize the files press the arrows beneath “Make Synchro”. The upper arrow that points left will prompt saving a new CEM dump file that is synchronized with the ECU. The second button which points right may be used to create a new ECU dump file instead. Choosing which function to use (create new CEM file or create new ECU file) is up to users’ personal preferences and basically there is no difference. It may be a good idea to base your decision, which module to synchronize, on the unit where it is easier for you to reprogram. As to our example, rewriting FLASH 28F400 is more difficult than 95P08. Therefore it may be a good choice to generate file for the ECU module and write it back. Click the bottom button “Make Synchro” and save the new ECU file. In any case the newly generated file has to be written back in its corresponding module, which will allow both modules to work together once again.

After the new file is generated it is advised to check the synchronization before applying it to the module. Following the example, Press “Load File” under CEM section within the software and select the newly generated by Tango file, which was created in the step above:

After that press Check Synchro:

Here is the tutorial on programming key for Toyota Previa MPV 8 seater when all smart keys have lost by CnAutotool.com engineer.

If you have original key, you can directly add key with Tango Programmer. But if you lost all your keys,you cannot directly add key.

Toyota straight key all keys lost: need to remove ECU immo box and do initialization data modification to add key.

Toyota smart remote key all keys lost: require not only remove immo box to initialize data but also remove ECU-Smart box to modify data to add key. Program Toyota Previa 2010 smart key all keys lost in 4 steps:

Step 1: Remove ECU immo box and ECU-Smart box

ECU Immo box is in the groove behind the evaporator under the dash. You need to disassemble the full dashboard. (See pic. below)

Toyota Smart box is behind the glove box near the A-pillar (see pic. below)

Step 2:Initialize IMMO data and Smart key box data Open ECU immo box 89784—28011, find out chip 93C46, read 93C46 data with ecu programmer,i.eXprog

Change all data marked blue to 0, these letters stand for key numbers. Initialization make it being key learning status, so it does not have key numbers, we change them to 0. The data marked in red are synchronized with engine computer data, DO NOT change them. Change all the rest data to F.

Open Toyota Denso Smart key box 89990-28131, find chip 93C86. Do not change data marked in red. Change all the rest data to F.

Step 3: Re-install IMMO box and smart box

Re-write data just read back to immo box and smart box. Re-install immo box and smart box to car. Switch ignition on, dashboard indicator turns on, you can connect Obd2 Key Programmer with car to build communication. Step 4: Add smart key Connect key programmer,i.e TM100,Tango with car Select Toyota Select Smart key programming Follow key programmer menu operation until the procedure is done

The new programmed key will start car directly Do not need to synchronize OBD 4-pin to 13-pin.

Note: Better initialize IMMO data with original data, do not use other car’s data to modify . If you initialize original data, the engine computer keeps the same data with immo which will save you 40 minutes to synchronize. It will directly start car.
