Defect Code 5

Defect Code 5:

Test functions:

Calling the test functions:

To a large extent, the test functions available provide information on the EKM since the calculations for the on-board computer functions are performed in the EKM. Observe following procedure (follow the sequence of operating steps as indicated):

1. Simultaneously press the numerical keys "10" and "1000". The large MID display shows: TEST-NO.:

Since the test functions are interlocked to protect them from unauthorized access, this interlock must first be canceled:

2. With the numerical keys, select the test function "19"; now enter the sum of the month and day numbers of the date set in the MID; e.g. 15.11: Sum = 15 + 11 = 26. The test functions can be accessed after pressing the SIR button. The SIR button must always be pressed after pressing a numerical button.

Attention: The test functions must be interlocked once again on completion of the test

Interlocking the test functions: Select function "19" and press SIR button:

Test functions are interlocked.

The following functions are available:

Enter number "1" : Display test; all elements and LEDs in both displays light up
Enter number "2" : Current consumption 1/100km
Enter number "3" : Current consumption I/h
Enter number "4" : Average consumption; the expected range is calculated with this value
Enter number "5" : Calculate current range
Enter number "6" : Current tank content
Enter number "7" : Average tank content; used to determine the expected range
Enter number "8" : Current speed km/h
Enter number "9" : Operating voltage terminal "15"
Enter number "10": Information relating to the MID: ab cd ef gh ij kl

where:
ab = Generation number
cd = Hardware number
ef = Software number
gh = Test schedule number diagnosis
ij = Calendar week of manufacture
kl = Year of manufacture


Enter number "11" : Country coding;

Attention: The setting must not be changed!

Enter number "12" : Average speed for expected time of arrival
Enter number "13" : Calculate current time of arrival
Enter number "14" : Date ROM of MID
Enter number "15" : Production diagnosis
Enter number "16" : Production diagnosis
Enter number "17" : Horn mode (intermittent/continuous tone)
Enter number "18" : not used
Enter number "19" : Lock/unlock test functions
Enter number "20" : keyboard test; a bar appears in the display equivalent to the point at which a key of the MID is pressed. Attention: The keyboard test is exited by ignition off/on.

After leaving the test functions, activate the interlock (see Point 2)
