SYMPTOM	POSSIBLE CAUSES	ACTION
Engine malfunction lamp illuminated	Selective catalyst reduction system failure Diesel exhaust fluid level too low Power or ground failure Diesel exhaust fluid pressure too low Diesel exhaust fluid pressure too high Diesel exhaust fluid injection pump Diesel exhaust fluid injector Diesel exhaust fluid relay Diesel exhaust fluid heater control unit Pre selective catalytic reduction NOx sensor Pre selective catalyst reduction Nox sensor module Post selective catalyst reduction NOx sensor Post selective catalyst reduction Nox sensor module Post selective catalyst reduction soot sensor Post selective catalyst reduction soot sensor module Diesel sub net CAN communication bus	Using the manufacturer approved diagnostic system check engine control module for related DTCs and refer to relevant DTC index Check and correct the diesel exhaust fluid level Refer to the appropriate SYSTEM WIRING DIAGRAMS information and check connections are secure and wiring integrity Refer to the service information and the battery care manual, inspect the vehicle battery and ensure it is fully charged and serviceable before performing further tests Inspect connectors for signs of water ingress, and pins for damage and/or corrosion Refer to the appropriate SYSTEM WIRING DIAGRAMS information and check sensor, relays/fuses and control module power feeds and grounds Check system for correct installation of components Check system mechanical and fluid integrity Check system for mechanical integrity Check system for leakage Check system for blockage
Engine will not crank	Vehicle battery failure Diesel exhaust fluid level too low Harness failure - Wiring integrity	Refer to the service information and the battery care manual, inspect the vehicle battery and ensure it is fully charged and serviceable before performing further tests Inspect connectors for signs of water ingress, and pins for damage and/or corrosion Check and correct the diesel exhaust fluid level Using the manufacturer approved diagnostic system carry out any required routines
Message warning	Selective catalyst reduction system failure A monitor of the historical diesel exhaust fluid consumption rate, allied with a direct reading of the diesel exhaust fluid level in the tank, predicts that the distance to emptying the tank is less than 2400km	Using the manufacturer approved diagnostic system check engine control module for related DTCs and refer to relevant DTC index Check and correct the diesel exhaust fluid level
