Read Diagnostic Trouble Codes

The Innova 3020d enables a user to view DTCs, including the anti-braking system (ABS), when connected to a vehicle. To check the codes, press the functionality you want to check on, for instance, the ABS button. After a few seconds, the scanner will retrieve the diagnostic trouble codes and display them.

The DTCs are usually stored in the controller’s memory. This scanner tool will display all the codes, and if the functionality is not supported by your car, it will show an error message.

Note that this scanner only displays codes found in the vehicle’s computer memory, and if there is no code, “0” will be shown. If there is one or more codes, press and release the button


With Innova 3020d, it is easy to read the diagnostic codes; it takes about 4-5 seconds to retrieve the code from the vehicle’s computer memory.


The Anti-Braking system (ABS) is not by all vehicles. Only Ford, Chrysler, and GM vehicles support this function. Always check the official website to know the list of vehicles covered.

Erases DTCs

Innova 3020d has an erased function that enables you to clear the DTCs from your vehicle’s computer and freeze frame data. In case you want to take your car to a repair later, don’t erase these codes. This is because the mechanic might need this information to understand the problem well.

When you erase the DTCs in your vehicle, the I/M readiness program will reset the entire monitor’s status to flashing condition. To set all the monitors back to normal status, perform the OBDII drive cycle.

When making this operation, liaise with the manufacturer’s manual to check how the OBDII test is performed.


The procedure of clearing the codes is simple. Note that after erasing, you can retrieve the code by pressing the erase button once again.


Erasing the DTC does not solve the problem that caused the code(s). If the necessary repair is not done, the code will reappear again after some time.
