Common symptoms of a faulty engine ECU
- engine does not start or intermittent starting problems;
- no diagnostic communication with the ECU;
- engine stalls while driving or after reaching operating temperature;
- incorrect operation of the ignition system or fuel injectors;
- multiple fault codes relating to circuits controlled by the ECU;
- problems with synchronization between the engine ECU and immobilizer.
Similar symptoms can also be caused by faults in the vehicle wiring, power supply, grounds, fuses or other components. We recommend carrying out a complete vehicle diagnosis before replacing the ECU.
Programming and preparation of the MT35E 2.4 ECU
The ECU is supplied in VIRGIN condition. The immobilizer memory and previously stored Car Pass data are cleared, allowing the module to be programmed to the vehicle in a similar way to a new replacement ECU.
- after installation, programming and immobilizer synchronization are required;
- adaptation can be performed using Tech-2, OP-COM or MDI diagnostic equipment;
- the correct Car Pass for the vehicle may be required to complete the procedure;
- after programming, the variant configuration should be checked and stored fault codes cleared;
- a 1:1 cloning service is available on request if the original ECU can be successfully read and is sent to us.
When cloning is requested, the data from the original ECU are transferred to the replacement module. The possibility of creating a complete clone depends on the condition of the memory and whether communication with the supplied ECU is possible.
