Mitsubishi FTO & EVO ECU Diagnosis Codes

Extracting Diagnosis Codes from the Engine ECU

The FTO’s engine ECU monitors everything from sensors to injectors, solenoid valves to ignition. If it notices a problem, it records this in the form of a diagnostic code. A Mitsubishi dealer equipped with the right MUT-II diagnostic setup is apparently capable of accessing these Mitsubishi FTO & EVO ECU Diagnosis Codes. The FTO Workshop manuals do not provide any alternative method for extracting diagnostic codes.

But did you know you can do this yourself, without needing anything other than this cheap-as-chips FTO & EVO OBD readout tool? (picture on the left side) It was created in 2017 and as a limited offer, we have only 10 pieces for sale. It is simple but it does the job! (SOLD OUT)

Just hit the contact form if you want one. Add your address details and you’ll receive a payment request via Paypal in return (you’ll need a valid PayPal e-mail account). When payment fulfilled, the tool will be sent to the address provided.

How to connect the Mitsubishi FTO & EVO ECU OBD readout tool

The first step is to remove the panel underneath the steering wheel. This simply requires the removal of four screws. Note that the bonnet release cable and lever will still be connected to this panel – just drop the panel down and keep it out of the way. Now if you crawl under there, you will notice an interface socket on the left hand side, about level with the bottom left screw you removed a moment ago. This is the location of the OBD diagnosis connector.

The second image to the left was taken with the camera facing directly up. All we have to do now is connect the OBD readout tool. With the engine ignition switch on, the computer will flash the engine warning light to indicate any stored diagnostic code(s).

Mitsubishi FTO & EVO ECU Diagnosis Codes

So what do Mitsubishi FTO & EVO ECU Diagnosis Codes look like when it is displayed? Check out below image!

This is blinking out diagnostic code 31. It does so by blinking the engine warning light for 3 long flashes and 1 short flash.

  • If no codes are currently stored, it will simply flash continually, once per second.
  • If more than one code is stored, it will display each one in a repeating sequence, eg. 31, 52, 64, 31, 52, 64…
  • To clear the codes, simply disconnect the car battery for 20 seconds or so.
