Directions for reading codes in dash using an E series JB4

To read codes via the in dash commands select menu 1 option 1 via your steering wheel controls.

1) The blinkers will flash twice and the speedo will move to indicate how many codes are stored.

2) The speedo will return to zero and begin reading out the codes. Each is a 4 digit number. Note the position of the speedo and reference the photo below to convert them to 0-9 and A-F code numbers. Those numbers can then be searched on this forum.

3) Each code will be followed by two flashes of the blinkers.

4) At the conclusion of the reading the blinkers will flash four times.

5) If the blinkers flash twice, then four times, with nothing in between, you have no stored codes.

Alternatively you can also read codes via the JB4 interface which will conveniently list the descriptions as well.
