DTC P21C7-13: Reductant Control Module Power Relay/Relays Control Circuit/Open - Circuit open: Action
NOTE:
A fault clear is NOT sufficient to clear the vehicle 'inducement' system warnings. The 'inducement' warnings automatically clear ONLY upon confirmation of the repair by the vehicle OBD system. The monitoring MUST be completed. The electrical checks normally occur when ignition is on or after engine start
- Prioritized Checks to Perform
- Refer to the electrical circuit diagrams and check the diesel exhaust fluid tank module circuit for short circuit to ground, short circuit to power, open circuit, high resistance
- Refer to the electrical circuit diagrams and check the diesel exhaust fluid relay circuit for short circuit to ground, short circuit to power, open circuit, high resistance
- Inspect connectors for signs of water ingress, and pins for damage and/or corrosion
- Install a new diesel exhaust fluid relay, only when diagnosed as failed
- Contact retailer technical support
- Vehicle Conditions to Enable DTC Logging Strategy
- Engine running
- On completion of the previous repair actions the following MUST be completed
- Using the Jaguar Land Rover approved diagnostic equipment, clear the Diagnostic Trouble Code(s) and retest
-
NOTE: The engine MIL is OFF (when engine ON)
- Start engine
- The 'inducement' warning clears automatically when the monitoring has completed and passed with no malfunction. This terminates the drive cycle
-
NOTE: If the engine MIL shows during the driving cycle, then the malfunction has re-occurred. Further repair is required
- Using the Jaguar Land Rover approved diagnostic equipment, clear the Diagnostic Trouble Code(s)
-
NOTE: This clears the fault storage from P2BAE/P2BAF
