Ensure that the correct troubleshooting steps are followed. To test for contamination of the DEF tank, refer to Systems Operation Testing and Adjusting, Diesel Exhaust Fluid Quality - Test.If the DEF is contaminated, Caterpillar recommends that the DEF tank is flushed. Refer to Systems Operation Testing and Adjusting, Diesel Exhaust Fluid Tank - Flush for the correct procedure.
