Possible Causes
- Purpose of the DTC
- To monitor interdigital electrode post selective catalyst reduction soot sensor, component protection
- Electrical Cause
- Mechanical Cause
- Control Module Signal Name
- Circuit reference CAN_L_3
- Circuit reference CAN_3_H
- Circuit reference SCRMRLY (power feed to post selective catalyst reduction soot sensor)
- Monitor Description
- Functional IDE shunt short circuit error of post selective catalyst reduction soot sensor
- Prioritized List of Possible Causes
- The powertrain control module has received an indication about the component that indicates a failure e.g. an intelligent actuator or sensor is indicating an internal fault
- CAN_L_3 circuit short circuit to ground, open circuit, high resistance
- CAN_3_H circuit short circuit to ground, open circuit, high resistance
- Post selective catalyst reduction soot sensor circuit short circuit to ground, open circuit, high resistance
- Connector is disconnected, connector pin is backed out, connector pin corrosion Inspect connectors for signs of water ingress, and pins for damage and/or corrosion
- Post selective catalyst reduction soot sensor soot deposits on probe
- Post selective catalyst reduction soot sensor water deposits on probe
- Post selective catalyst reduction soot sensor failure
- DPF damage
