  1. Enter the service mode. Select the “ACTIVE ERROR” option on the second line by using the keys for direction.

    Illustration 2 g00687943

  1. The area that is highlighted in the illustration is showing the number of the error out of the total number of errors that are present.

    Illustration 3 g00687952

  1. The left arrow key and the right arrow key is used to display the error codes that are active. These keys are used to scroll through the codes. The illustration above shows the “MID-CID-FMI”. The “69” is the MID. The “1162” is the CID and the “04” is the FMI. The arrow keys are used to scroll through the active diagnostic codes.
