Message.
Timeout error of CAN-Receive-Frame

DEF dosing valve is blocked with
crystallized urea or other deposits.
SECTION 3 - CHASSIS & TURNTABLE
Possible Cause
Time out of Check CANBUS EAT Control
Receive
Message, PGN65348.
The message is not received.
If the frame CM1 message is not transmitted
successfully
Timeout Error (Missing CAN Bus message)
Timeout Error (Missing CAN Bus message)
While SCR system is starting up and fter urea
pressure reaches 10000 hPa, the DEF
dosing module is tested. Expectation is that
urea pressure drops below 1500 hPa if
injector works properly. The test is repeated
up
to 3 times before an error is set.
SCRSysPresMon_stPresDropDet_mp = 0
while SCRCo_stStatus_mp = 16.
Suspected component:
wiring harness
DEF dosing valve
The error is stored into the EEPROM of the ECU
and status at ECU shut down is regained at
ignition on.
Action
Threshold for error detection is an internal ECU
threshold.
Check CANBUS EAT Control Receive Message,
PGN65348.
CM1 Module Customer Receive Message.
Check CAN Bus cabling (Bus scheduling,
polarity, short circuit, power interrupt), test
protocol of receiver, check CAN functional
range.
Check CAN Bus cabling (Bus scheduling,
polarity, short circuit, power interrupt), test
protocol of receiver, check CAN functional
range.
Check CAN Bus cabling (Bus scheduling,
polarity, short circuit, power interrupt), test
protocol of receiver, check CAN functional
range.
Check electrical connection of urea injector:
- wiring harness
- connector
Conduct SERDIA use-case "injection test". If it
is faulty:
- remove urea injector from exhaust line:
- check for crystallisation direct on injector
noz- zle / plate
- rinse it thoroughly in water
- remount urea injector and conduct SERDIA
use-case "injection test"
If the error is still active, then exchange urea
injector.
