U1218 Diagnostic Trouble Code (9 interpretations)

The control module detected that the value received for the Fault in the engine oil or intake air temperature information received by the CAN (Engine ECU) over the network was incorrect. Documented for the AM6/AT6 automatic gearbox ECU on Peugeot applications; the same PSA control units are also fitted to Citroën models.

The control module detected that the value received for the Fault in communication with the BSI over the network was incorrect. Documented for the Automated manual gearbox electric control ECU on Peugeot applications; the same PSA control units are also fitted to Citroën models.

The control module detected the fault condition "Data invalid" for the Fault absence of communication with the built-in systems interface. Documented for the Bosch ESP 8.1 stability control ECU on Peugeot applications; the same PSA control units are also fitted to Citroën models.

The control module detected an internal control-unit fault (Absence of frames). Documented for the Bosch MED 17.4.x engine ECU (EP6 THP family) on Peugeot applications; the same PSA control units are also fitted to Citroën models.

The control module detected an internal control-unit fault (One of the parameters present in a datastream sent by the BSI is invalid). 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 an internal control-unit fault (One of the parameters present in a frame emitted by the BSI is invalid). 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 that the value received for the Fault in the information transmitted by the BSI ECU over the network was incorrect. Documented for the MCP 6-speed piloted manual gearbox ECU on Peugeot applications; the same PSA control units are also fitted to Citroën models.

The control module detected that the value received for the Communication with the BSI over the network was incorrect. Documented for the Magneti Marelli MM6KP engine ECU (EW7A/EW10A) on Peugeot applications; the same PSA control units are also fitted to Citroën models.

The control module detected that the value received for the CAN communication over the network was incorrect. 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.
