Possible Causes
- Purpose of the DTC
- To monitor diesel exhaust fluid tank module - output from the ECM to DEF pump control for open circuit
- Electrical Cause
- Mechanical Cause
- Control Module Signal Name
- Monitor Description
- Diesel exhaust fluid tank module - output from the ECM to DEF pump control open circuit
- Prioritized List of Possible Causes
- The powertrain control module has determined an open circuit via lack of bias voltage, low current flow, no change in the state of an input in response to an output
- Diesel exhaust fluid tank module circuit open circuit, high resistance - output from the ECM to DEF pump control
- Connector is disconnected, connector pin is backed out, connector pin corrosion
