7. Troubleshooting
In case of a malfunction of the light an error code
is shown on the display of the key pad, as shown
in the picture on the left.
The error codes consist of four digits.
The error shown on the display is always the error
with the highest priority:
 Errors of the control board are prior to errors of
the cluster boards.
 Clusters with lower adress have higher priority.
 General cluster errors are prior to errors of the
LED channels.
 In case of general cluster errors the lower num-
bers have the higher priority.
Decoding
Digit 1 Digit 2 Digit 3 Digit 4
c 0-7 * *
Cluster errors always begin with the letter 'c';
digit 2 is the cluster adress (0-7)
c 0-7 - -
No contact to the cluster
c 0-7 - *
General cluster error (reported by the cluster); reset by switch-
ing ON and OFF
Digit 4 = Bit-number oft he error (MADA-
TAID_CANPAR_STATUS_xxx)
c 0-7 - 0
WDRESET CPU was reset by WD
c 0-7 - 1
SWRESET SW reset because of fatal error
c 0-7 - 2
FLASHCRC FLASH CRC error
c 0-7 - 3
RAMERR RAM test error
c 0-7 - 4
NOEEDATA no EEPROM data, defaults were
used (SerNum etc. lost)
c 0-7 - 5
EEDEFAULT EEPROM paramater defaults were
set (SerNum etc. preserved)
c 0-7 - 6
EEWRERR EEPROM write error when writing
parameters
c 0-7 - 7
reserved
c 0-7 - 8
UNDERVOLT 24V supply undervoltage
c 0-7 - 9
NOCOMM no data received for too long a time
c 0-7 0-7 *
LED-error; reset by switching ON and OFF
Digit 3 = LED-channel: 0-7 =
CW1,WW1,G1,R1,CW2,WW2,G2,R2
Digit 4 = error code, in case of multiple codes they are added
(MADATAID_CANPAR_STATUS_LED_xxx)
c 0-7 0-7 1
OFFCURR current measured in driver OFF
state
c 0-7 0-7 2
UNDERCURR open circuit / cannot reach target
current
c 0-7 0-7 4
OVERCURR short circuit / measured current is
too high
