The error 027 occurs due to that the registration period of the unit has been completed and, therefore, you cannot use the diagnosis functionalities until the register of your Jaltest product is being carried out.
Please, close the program and execute it again in order to carry out the registration process correctly.
If the problem persists, contact customer support at (305) 960-7651 or email us at customersupport@jaltest.com.
