IMPORTANT

•

If the control module part number is 55354002 for B202E/L or 55354562 for B207R, the module should be updated to the latest software since these parts can incorrectly generate a DTC. If the part number is later than the numbers indicated, perform the normal fault diagnosis. The DTC can remain after SPS programming if the fault is genuine.
