17. Fault codes, retarder 133
To the right of the bus instrument cluster there is a green checklamp (5022) for the
retarder function and fault indications. At every voltage inflow the lamp will normally be
lit for five seconds, if the lamp doesn’t go out after five seconds have passed, a fault code
is set in the retarder. The fault codes set in the retarder can be read via blink codes on the
checklamp (5022) which can blink with two different intervals, long blink (2 seconds) to
represent multiples of ten and short blink (0,5 seconds) to represent singular. For instance
a combination of two long and two short blinks represents the number 22. A short look at
the table below shows that 22 means “ABS signal internal control unit error”.
The fault codes set in the retarder can be show by first turning the ignition on and off and
then on again. Then press the lever to the position 1 and immediately back to position 0.
The first fault code will now be displayed as an icon on the control lamp. Repeated
movement of the lever between position 1 and position 0 will display the next fault code
in line, if the same fault code is shown two times in a row there are no more fault codes
set in the retarder.
