Engine diagnosis indicator lamp lights up in instrument cluster and fault code P203B00 is stored in the AdBlue® (SCR) control unit Topic number LI14.40-N-069569 Version 2 Function group 14.40 Exhaust aftertreatment, AdBlue Date 09-09-2019 Validity Model 906 as from 01.07.13 with engine 651 Model 906 as of 01.07.13 with engine 642 Reason for change Remedy added for noticeable problems with the capillary stop connectors of the electric lines between the AdBlue® control unit (SCR) and the AdBlue® tank module (A102). Reason for block Complaint: Engine diagnosis indicator lamp lights up in instrument cluster and fault code P203B00 stored in AdBlue® (SCR) control unit. Cause: • • • Erroneous refueling of AdBlue® tank. Poor contact of AdBlue® fill level sensor on electrical plug of AdBlue® tank module (A102). Temporary resistance in the capillary stop connectors of the electric lines between the AdBlue® control unit (SCR) and the AdBlue® tank module (A102). Remedy: 1. Visually inspect AdBlue® tank for signs of erroneous refueling. Information: To do so, check the AdBlue® concentration level (see AR14.40-D-2041S for model 906). In the event of any erroneous refueling, the repair work must be conducted as per the procedure in the Service Information bulletin SI14.40-S-0014A. 2. _______________________________________________________________________________ Check function of AdBlue® fill level sensor using actual values for fill level of AdBlue® tank (absolute value) in XENTRY Diagnosis. Information: Extract approx. 2-3 liters of AdBlue® from AdBlue® tank (see AR14.40-D-2014-02A and AR14.40D-2014-02S for model 906), the fill level in the AdBlue® tank must change accordingly. If there is no change in the fill level in the AdBlue® tank, research further to determine reason for problem and introduce appropriate repair measures. 3. _______________________________________________________________________________ Check electric lines between AdBlue® (SCR) control unit and AdBlue® fill level sensor in AdBlue® tank module (A102) (see picture 01). 09-09-2019 11:15 PM © Copyright Daimler AG BSTRINE Page 1/6 Information: If there are any noticeable faults with the electric lines between the AdBlue® (SCR) control unit and the AdBlue® fill level sensor in the AdBlue® tank module (A102), appropriate repair measures must be introduced. 4. _______________________________________________________________________________ Replace coupling housing, contact sockets and single conductor seals of electrical plug on the AdBlue® tank module (A102) (pins 3, 4 and 5 (contacting of fill level sensor)) (see picture 01). Information: Conduct only when operation steps 1, 2 and 3 are conducted without any noticeable problems. To repair the electrical plug, please refer to documents AR00.19-D-0100A (model 906), and AR00.19-S-0120E. _______________________________________________________________________________ Note: In the event of noticeable problems with the capillary stop connectors of the electric lines between the AdBlue® control unit (SCR) and the AdBlue® tank module (A102), the capillary stop connectors must be replaced with solder terminal connectors in accordance with the relevant instructions (see AR00.19-P-0100-09A). Info: For the layout of the capillary stop connectors of the electric lines between the AdBlue® control unit (SCR) and the AdBlue® tank module (A102), see picture 03.
