8 manufacturer-specific interpretations across 4 manufacturers in the TuningBot DTC database.
Ford
1 interpretation
Honda
1 interpretationThe control module detected a fault associated with the Charge/discharge balance problem circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by Honda.
Possible causes
- Low 12V battery
- charging system malfunction
- 12V battery
PSA
4 interpretationsThe control module detected the fault condition "Additive system fault" for the Particle filter additive system. Documented for the Bosch EDC16C34 injection ECU (DV6TED4 1.6 HDi) on Peugeot applications; the same PSA control units are also fitted to Citroën models.
The control module detected the fault condition "CAN network fault or pump fault" for the Multiplexed additive pump. Documented for the Continental SID 807 injection ECU (DV6C 1.6 HDi) on Peugeot applications; the same PSA control units are also fitted to Citroën models.
The control module detected the fault condition "Network CAN fault or additive pump fault" for the Multiplexed additive pump. Documented for the Delphi DCM 3.5 injection ECU (DW10C 2.0 HDi) on Peugeot applications; the same PSA control units are also fitted to Citroën models.
The control module detected the fault condition "No communication with additive ECU" for the Additive system. Documented for the Siemens SID 803 injection ECU (DW10BTED4 2.0 HDi) on Peugeot applications; the same PSA control units are also fitted to Citroën models.
VAG
2 interpretationsThe control module detected a short circuit to ground in the Secondary air injection (AIR) pump relay circuit. This is the manufacturer-specific definition used by Audi.
Possible causes
- Wiring short to ground
- AIR pump relay
