SERIAL COMMUNICATION ERROR
The communication between the Central Control Unit (CCU) and the Motor Control Unit (MCU) cannot be sent correctly.


1. Unplug washer or disconnect power.
2. Check wire harness connections to the MCU, the motor, and Central Control Unit (CCU).
Check connections of the CCU board within the housing.
Make sure all grounding switches are engaged.
3. Check the drive system for any worn or failed components.
4. Plug in washer or reconnect power.
5. Verify CCU operation by running a Diagnostic Test or any cycle.
6. Check the MCU by looking for operations of the drive motor.
7. Check the drive motor for powered rotations.
8. Check that the serial harness at the MCU is not mounted upside down. The wires should be to the left when facing the MCU connectors.

hi,
clean your unit first using lacquer thinner,then blow it slightly by hot air...after doing that clean the pin out because if it water damage it must be corroded...what version of jaf you are using?if your version are not updated ,1202 is a sl3 (simlock 3) unit and not supported by lower version of jaf...much better if you use mx key dongle and ufs box as your interface (do not use jaf as your interface because it would be damage) or cyclone....and here is the procedure..
using easy cable ,connect the phone ,open mx key module ,select ufs interface ,dct4 then bus check...if the info of unit is showed ,put CNT ,MCU,PPM ..before flashing back up your phones rpl first ...then flash the phone...after flashing ,there is a possibility that the phones status is contact service ,dont worry just go to service ,imei and security then direct unlock...but be sure that your mx key is activated by dct4 plus unlocker...
in case the phone is not responding after cleaning ,reheat flash ic then repeat the procedure...i hope it will help you ,thanks for trusting fixya..
goodluck..
